Health Insurance Case Scenarios

(Health Insurance Case Scenarios)

Health Insurance Basic Questions

1. Mrs. Washington was involved in a traffic accident. She saw Dr. Grace because of pain in her right knee. She explained that this pain was the result of her knee hitting the dashboard on impact. Mrs. Washington has a history of arthritis in both of her knees. Dr. Grace listed her diagnosis from this visit as bilateral degenerative joint disease. What are the consequences of this diagnosis on Mrs. Washington’s case?

2. Anthony is 17 years of age and attending college in Maine. One day while skiing, he broke his leg and was taken to the emergency room of the local hospital. When filling out the necessary paperwork, whom should Anthony name as the party responsible for the charges incurred?

3. Mrs. Cassidy called her physician’s office complaining that her insurance company was billed twice for her office visit on November 19. Carole pulled Mrs. Cassidy’s file and verified that this was true. She apologized for the error and assured Mrs. Cassidy that she would correct this error. What steps should be taken to avoid duplicate billing

4. Mrs. Ellison called her doctor’s office and spoke with Lorraine about a bill from her recent visit. Mrs. Ellison has been Dr. Johnson’s patient for many years, although prior to her recent visit it had been some time since she saw Dr. Johnson. Mrs. Ellison was sure that there was a billing error because she was billed for a new patient visit. How should Lorraine handle this patient’s inquiry

5. Allison was working at the reception desk during a department staff meeting. She normally worked in medical records and therefore had an understanding of the importance of patient confidentiality. When a caseworker from a workers’ compensation case arrived and asked to discuss a patient’s case with the physician, Allison explained that she would need a signed release form from the patient before that was possible. Did Allison handle this situation correctly?

6. Jamie is reviewing Mr. Murphy’s medical file to process his insurance claim. She has difficulty reading the doctor’s notes, but rather than flag the file to check with the doctor, Jamie makes an educated guess and completes the insurance form. What are some possible consequences of Jamie’s actions?

HEALTHCARE ETHICS

ASSIGNMENT 2

HA570-1: Critique the need for and role of ethics in the American healthcare environment.

Instructions:

As you have learned, differences exist between morality, ethics, and the law. Morality refers to an individual‘s moral compass or belief system based on their individual perspective. Ethics refers to the standard of action that should be performed, irregardless of an individual‘s perspective, opinion, or ideology. Law simply refers to any legal requirements involved.

In an ethical dilemma, varying perspectives exist. Oftentimes, these perspectives include the patient, provider, caregiver, family member, or staff member. Every person has a unique perspective and it is these unique experiences that form our belief system. As a future leader in healthcare administration, it is important to identify and understand how these varying perspectives act as a foundation for individual morality and influence our decisions. Likewise, it is also important to understand that despite personal morality, providers are required to abide by the ethical standards present in the field.

In this unit, you will explore the differences between morality and ethics by examining a scenario and its implications from varying perspectives. By the end of this unit, you will be able to proficiently discuss the need for and role of ethics in the American healthcare environment.

To begin, select one (1) of the following stories from your textbook from which to address the assignment requirements:

· The Story of the Harvey Family and the Interprofessional Care Team (p. 3)

· The Story of Pat Jackson, the Interprofessional Care Team, and Mr. Sanchez (p. 29)

HA570-2: Assess national regulations regarding confidentiality and ethical considerations of confidentiality laws.

Instructions:

As you have learned, regulations and laws exist to protect patient privacy and uphold confidentiality. Especially in a technological advanced setting, such as healthcare, maintaining these standards can prove challenging as a result of new, ethical issues not previously experienced. As a future leader in healthcare administration, it is important to understand national regulations relative to confidentiality, privacy, and informed consent.

In this unit, you will compare ethical issues of confidentiality by examining a scenario and its implications of various regulations and laws. By the end of this unit, you will be able to assess national regulations regarding confidentiality and ethical considerations of confidentiality laws.

To begin, select one (1) of the following stories from your textbook from which to address the assignment requirements:

· The Story of Twyla Roberts and Mary Louis (p. 203)

4: Analyze the effect ethics has on day-to-day operations as well as long-term policy and procedure in a healthcare environment.

Instructions:

As you have learned, the population segment aged 65 and older is rapidly aging in the United States. As a result, new ethical challenges are emerging in the field, specifically in long-term care (i.e. skilled nursing facilities including those with post-surgical short-term rehabilitation services).

One area of concern is the challenge of providing adequate healthcare services to a growing (and aging) population with limited resources. This dilemma is expected to increase as the population continues to increase. As a result, the demand for medical services increases; however, with finite healthcare resources, providing services to everyone who requires care is not possible.

This will present a unique challenge for nursing home administrators because they are responsible to ensure that resident needs (including receiving healthcare services) are being met. Determining who should receive the necessary care that is available will be an interdisciplinary challenge indeed.

Scholars have posited a variety of allocation methods; however, these principles have not been without controversy. One of the most recent principles introduced is the Complete Lives System. This method is unique, because unlike its predecessors that relied on a unilateral perspective, the Complete Lives Systems takes a multi-allocation system approach.

In this unit, you will combine your previous knowledge obtained throughout the course and apply clinical reasoning to evaluate moral action and its relevance to ethical-decision making in long-term care. Using ethical decision-making, you will determine the best method of allocating limited medical resources to a growing and aging population. By the end of this unit, you will be able to analyze the effect ethics has on day-to-day operations as well as long-term policy and procedure in a healthcare environment.

Please review the following resources and using specific information from these resources, your course materials, and additional research, address the tasks posed below.

Three individuals in town require a hip surgery, followed by extensive rehabilitative therapy. Physical and occupational therapy will be provided at the skilled nursing facility where the individual will reside until able to return home. Below are details of each individual.

· Donna Mueller is a 58-year old disabled widow with no children. She spent her career as a homemaker and taking care of her husband. Donna requires surgery after falling at home while washing windows. Prior to the accident, Donna was relatively independent, although a stroke a few years prior left her partially paralyzed. She lives alone and has minimal company over.

· Steve McDonald is 40-year old unemployed musician. He has a teenage son who lives with the son’s mother in a neighboring town. At the age of 19, Steve left college to pursue a career as a drummer. For the past two decades, Steve has worked odd jobs while pursuing his dream. Although his perseverance has not landed him national attention, he has performed with a few, known bands in the area. Recently, while exiting stage left from a nightclub performance, Steve tripped over the dark stairs and fractured his hip, ultimately leaving him unemployed as he is currently unable to perform.

· Chris Snider is a 73-year old entrepreneur and business owner. Never married, Chris spent his career in the fast-pace, produce or perish industry of nanotechnology where he employs over 5,000 workers ranging from maintenance technicians to senior research engineers. Chris requires surgery after being innocently hit with a runaway golf cart on the back 9 with his visiting, foreign affiliates. Chris was completely independent prior to the accident. He lives alone; however, his business requires travel.

In a 6-8 page paper (excluding title page and reference list), address the following:

· Considering the aging population and existing challenges, discuss the potential role of allocation principles in the American healthcare system.

· Discuss the potential implications these principles have on the aging population (consider potential violations of federal antidiscrimination laws and ethical principles about fair treatment).

· Based on the Complete Lives System, discuss which individual would most likely receive the surgery.

· Based on your moral compass, ethical standards, and healthcare laws, discuss which individual you would recommend for surgery.

· Recommend the one allocation principle you would prefer as the primary medical intervention for a growing (and aging) population.

Report your findings noting the following standards:

· Current APA formatting (e.g. title page, citations, conclusion, reference page, etc.) should be used.

· Proper grammar, spelling, and punctuation are expected.

· Plagiarism, self-plagiarism, unoriginal work, and unattributed content is not permitted and will result in action pursuant to the University’s Plagiarism Policy and Procedures.

ICD-PCS Coding

M132 Module 02 Coding Assignment

Find the correct code and explain your rationale for each case study below.

1. Case Study:

PREOPERATIVE DIAGNOSIS:

1. Gangrene right foot.

POSTOPERATIVE DIAGNOSIS:

1. Gangrene right foot.

OPERATION:

1. Right below the knee amputation.

ANESTHESIA: General LMA.

PROCEDURE: The patient was brought to the operative suite where a general LMA anesthesia was induced.

A Foley catheter was inserted. The right foot was s secluded in an isolation bag and the right lower extremity circumferentially prepped and draped in its entirety. Beginning on the right side the skin was marked with a marking pen 4 fingerbreadths below the tibial tuberosity anteriorly with a long posterior flap. The skin was incised circumferentially and the anterior musculature sharply divided exposing the tibia The tibia was cleaned with a periosteal elevator and then transected with the Stryker saw. The fibula was exposed and transected with the bone cutter and the amputation completed by sharply incising the posterior musculature. Bleeding vessels were ligated with 2-0 silk Ligature. There appeared to be adequate bleeding at this level for primary healing. The tibia was then cleaned with a bone rasp and the fibula with a rongeur. The wound was irrigated and ultimately closed without significant tension utilizing interrupted 2-0 vicryl sutures for reapproximation of the fascia and skin staples for reapproximation of the skin.

The right side was dressed with sterile gauze fluff dressings and a Kerlix roll. Estimated blood loss throughout the procedure was approximately 150 mL. The patient received one unit intraoperatively of packed cells because of preoperative anemia. She was transported in stable condition to the recovery room.

2. Case Study:(Clinical Procedure Coding Practice)

PROCEDURE: Open reduction and internal fixation of bilateral tibial plateau fractures.

INDICATIONS: This 23-year old was involved in a serious accident and sustained bilateral tibial plateau fractures

DESCRIPTION OF OPERATION: The patient was brought to the operating room and placed on the operating room table in the supine position. General anesthesia was induced, and after this both lower extremities were prepped and draped in the usual sterile fashion. Attention was first directed towards the left tibial plateau. A standard lateral procedure to reduce the lateral tibial plateau fracture was performed. After a submeniscal arthrotomy was performed, the joint was visualized via the lateral approach. The posterolateral fragments were reduced and the lateral tibial plateau was elevated, restoring the articular surface. K-wires were placed to provisionally hold this reduction. C-arm fluoroscopy was used to confirm good reduction of the joint surface. Next, a 6-hole lateral plateau locking plate from the Stryker sets was selected. This locking plate was advanced down the tibial shaft. Screws were placed to secre the plate to the bone. Four screws were placed in the distal shaft fragments and 4 locking screws in the proximal fragment. A kickstand screw was also placed in the locking mode. After all screws were placed, x-rays exhibited good reduction of the fracture, as well as good placement of all hardware. Next, the wound was thoroughly irrigated with normal saline. The meniscal arthrotomy was closed with the 0 PDS suture, including the capsule. Next, the IT band was closed with 0 Vicryl suture, followed by 2-0 Vicryl sutures for the skin and staples. Attention was then directed toward the right tibial plateau. A similar procedure was performed on the right side. Then, the lateral approach to the lateral tibial plateau was performed, exposing the fracture. The incision was approximately 4 cm on the right side. A 6-hole LISS plate was advanced down the tibial shaft. Four screws were placed in the distal fragments followed by four screws in the locking mode and proximal metaphyseal fragment. Excellent fixation was obtained. The C-arm fluoroscopy was used to confirm excellent reduction of the fracture on both the AP and lateral fluoroscopic images. Next, the wound was thoroughly irrigated and closed in layers. Sterile dressings were applied All wounds were dressed with sterile dressing and the patient was placed into knee immobilizers. The patient was then awakened from anesthesia, and transferred to recovery. The patient will be nonweightbearing for approximately three months on bilateral lower extremities. The patient will receive DVT prophylaxis during this time.

3. Case Study:(Clinical Procedure Coding Practice)

PREOPERATIVE DIAGNOSES:

1. Pelvic pain.

2. History of previous pelvic surgery and ovarian cyst.

POSTOPERATIVE DIAGNOSES:

1. Pelvic pain.

2. History of previous pelvic surgery and ovarian cyst.

OPERATION PERFORMED: Laparoscopic adhesiolysis.

SURGEON: Susan Smith, MD

ANESTHESIA: General endotracheal.

ESTIMATED BLOOD LOSS: Less than 10 mL.

URINE OUTPUT: 70 mL.

IV FLUIDS: 750 mL.

DESCRIPTION OF OPERATION: After informed consent was obtained, the patient was taken to the operating room. She was placed in the dorsal supine position and general anesthesia was induced and prepped and draped in the usual sterile fashion. A Foley catheter was placed to gravity and speculum was placed in the posterior and anterior vagina and the cervix was grasped with a single-toothed tenaculum. A Hulka clamp was then inserted through the cervix into the uterus for uterine manipulations and the tenaculum was removed and attention was then turned to the abdomen.

A supraumbilical incision was made with a scalpel and elevated up with towel clamps. A long Veress needle was then placed and CO2 gas was used to insufflate the abdomen and pelvis. A 10-12 trocar and sleeve were then placed and confirmed via the laparoscope. The dense greater omental adhesions to the anterior abdominal wall were noted immediately. At this time, we were not able to see into the pelvic region. A second 5 mm trocar and sleeve were placed in the left mid quadrant under direct visualization. The ligature device was then placed developing a plane between the omentum and the anterior abdominal wall.

The adhesiolysis took place and it took approximately 25 minutes to release all of the omental adhesions from the anterior abdominal wall. We were then able to visualize the pelvis and a blunt probe was placed through the port. The ovary was visualized and photos were taken with no evidence of any ovarian cyst or ovarian pathology or of pelvic endometriosis. The uterus also appeared normal and the left tube and ovary were surgically absent. The appendix was easily visualized and noted to be noninflamed, normal in appearance, and there were no adhesions in the right lower quadrant. The upper abdominal exam was unremarkable. The procedure was terminated at this time. The ports were removed. CO2 gas was allowed to escape. The incisions were closed with 4-0 Vicryl suture. The Hulka clamp was removed. The vagina was noted to be hemostatic. The patient’s anesthesia was awakened from anesthesia, the Foley catheter was removed, and she was taken in stable condition to the recovery room.

Part A: STANDING WAVES ON A STRING Using PhET simulation

(Part A: STANDING WAVES ON A STRING Using PhET simulation) 12/27/2019

OBJECTIVE

To study standing waves on a string and see the effects of changing the tension in the string,

EQUIPMENT

PhET Simulation Wave on a String: https://phet.colorado.edu/en/simulation/wave-on-a-string

You can also reach this simulation by going to PhET, and looking for Wave on a String.

 

Theory: Standing Waves in Strings

For any wave with wavelength λ and frequency f, the speed, v, is

v = λf (1)

The speed of a wave on a string is also related to the tension in the string, T, and the linear density (=mass/length), μ, by

v2 = T/μ = λ2f2 (2)

L is the length of the string and n is the number of segments, antinodes, or harmonics. Since a segment is 1/2 wavelength then

λ = 2L/n where n = 1, 2, 3, … (3)

Solving Equation 2 for the tension yields:

T = μλ2f2 (4)

Which can also be written as:

(5)

PROCEDURE

Constant Tension

1. Open the software. Select: Oscillate, Amplitude = 0.10 cm, Damping = 0, Tension = Lowest, Fixed End.

2. Turn on the oscillator by pressing the large blue button with the arrow. You will see the wave going from left to right, hit the fixed end and reflect. The reflected waves will interfere with the waves going to the right.

3. Now adjust the frequency in the Signal Generator until you get a standing wave in one segment (i.e. the first harmonic). Note this frequency, and measure the wavelength by using the ruler tool. (Part A: STANDING WAVES ON A STRING Using PhET simulation)

4. Increase the frequency gradually until you obtain a standing wave in the 2nd, 3rd, 4th, and 5th harmonic. Record each frequency and wavelength.

5. Calculate the wavelength by using equation (3).

6. Calculate the velocity of the waves by using equation (1)

7. Change the oscillator to Pulse. Keep the pulse width small. Measure the time taken by the pulse to travel from the left to the right ends, and hence calculate the velocity of the pulse in the string. Repeat three times and take the average. Use this value as a second value of the speed of the wave.

8. Calculate the percent difference between the two speeds.

Part B E-39-0 Electric Charges and Electric Fields ONLINE

6-21-2020 Adapted from manual from Dr. Kam Chu

 

Objective

To study the electric field and electric potential around different charges.

 

Equipment

PhET Simulation:

https://phet.colorado.edu/sims/html/charges-and-fields/latest/charges-and-fields_en.html

 

Theory

There is an electric field surrounding a charge, in which another charge would experience an electric force. The strength of the electric field at a distance from a point charge is given by:

(1)

Where is the Coulomb Constant, q is the charge, and r is the distance from the charge. The unit vector points away from a positive charge, and towards a negative charge. (Part A: STANDING WAVES ON A STRING Using PhET simulation)

 

The electric potential due to a point charge is given by the equation:

(2)

Where is the electric potential (in volts), and is a scalar quantity.

 

In this Lab, we will use a PhET simulation to study the electric field and electric potential surrounding single and multiple point charges.

 

Procedure

Play with the simulation (Charges and Fields) and get oriented with all the different options. This should help you understand the lab better. Note that you have positive and negative point charges, an electric field sensor (yellow circle), a tape measure and a voltmeter, that also makes the equipotential lines. For each case, take a screenshot and attach with your report. You may alsoturn on ‘gridlines’ if desired. Each small square of the grid is 10 cm wide and high. (Part A: STANDING WAVES ON A STRING Using PhET simulation)

 

Activity 1: Electric Field Lines and Equipotential Lines

1: Have one positive and one negative charge placed symmetrically in the field. Get the Electric field lines. Use the voltmeter to draw about ten equipotential lines (Figure 1 shows a related situation with a few equipotential lines)

2: Repeat with both charges being negative.

3: Repeat with both charges being positive.

4. Repeat with 4 positive charges (on top of each other, to create 4q) and one negative charge.

5. Parallel Plates: Put a large number of positive charges in a straight row (to look like a solid line). Make a negative line in the same way (parallel to the first). As an example, see figure 2. Get the electric field lines and Equipotential Lines between and surrounding the parallel plates.

6. Attach screenshot of the simulations in your report. Figure – 1

Figure-1: Parallel “plates”. 

 

 

 

 

 

 

ACTIVITY 2

1) Turn on ‘gridlines’.

2) Select positive point charge of any magnitude (you do this by placing the point charges on top of each other). Place the charge at the intersection of two thick gridlines, somewhere in the left half of the screen.

3) Use the tape measure and Voltmeter to find the voltage at different locations along the horizontal line on which the charge is placed. Enter values in Table 1.

4) Plot a graph in Excel between the voltage (y-axis) and the distance (x-axis).

5) Use Excel to determine the value of the Coulomb Constant (see eqn. (2). Find the percent error between the calculated and accepted values.

6) Use the tape measure and the yellow Electric Field sensor to measure the electric field at different distances in the horizontal direction from the charge. Enter the data in Table 2.

7) Plot a graph in Excel between the Electric Field (on y-axis) and distance (on x-axis)

8) Use Excel to determine the value of the Coulomb Constant (see eqn. (1)). Find the percent error between the calculated and accepted values.

9) Attach the screenshots, graphs and calculations to your report. (Part A: STANDING WAVES ON A STRING Using PhET simulation)

1. Open the simulation by ctrl+click the link, or copy paste the link to the browser. The simulation should look like that shown in Fig.6

2. Since this simulation is in java (and not web based as some of the others), you may have to download the simulation. If you cannot run the simulation, you may need to follow the following PhET help guidelines: https://phet.colorado.edu/en/help-center/running-sims

Then click “Why can Irun some of the simulations but not all?”

3. Run the simulation, and you will see a page like that shown in Fig.7.

4. You would not set up the circuit. For assistance in setting up the circuit, see the manual: 00PhET Simulation Tool Instructions for Electric Circuits Labs.

5. This experiment requires you to measure the voltage as a function of time. The timer can be easily controlled by using the Pause/Play button (►) and/or the step button (|►) (these are at the bottom of the page).

 

 

 

 

 

 

 

 

Figure 6. Figure 7.

Case-A: charging the capacitor.

1. Set up the circuit as shown in figure 8. Once set up, it should look something like that shown in figure 9.

2. Set the resistance to 100 Ω, capacitance to 0.05 F, and Battery to 10.0 V.

3. Before charging the capacitor, make sure that it has no charge (the voltmeter reads zero). Otherwise you need to discharge the capacitor first until the voltage across the capacitor becomes zero. (Part A: STANDING WAVES ON A STRING Using PhET simulation)

4. Put switch S1 in the ON state and switch S2 to the OFF state.

5. Set the Pause/Play button (►) to pause and the timer to zero. Before 5 seconds, use the step button (|►) to increase time by 0.5 second intervals and record the voltage values in Table I. After 5 seconds, use the Pause/Play button (►/||) to record the voltage at around 7.00, 10.0, 15.0, 20.0, and 25.0 seconds.

6. Using equation (5), obtain the charge at each time, and enter in Table 1.

7. Draw a graph between charge on y-axis and time on x-axis. It should look like Fig. 3.

8. Use the known values of resistance and capacitance to calculate the time constant and the maximum charge by using eqn. (2) and eqn. (3), and enter in Table 2.

9. Calculate the charges equal to one time constant, two time constants, and five time constants and enter in Table 2. Compare these with the experimental values using % error. Put your calculation in the table II.

Case-B: Discharging capacitor

1. Set up the circuit as shown in figure 8.

2. Set the resistance to 100 Ω, capacitance to 0.05 F, and Battery to 10.0 V.

3. Before discharging the capacitor, make sure the capacitor has been fully charged (the voltmeter reading is very close to 10.0 V).

4. Set switch to off and switch to on.

5. Set the Pause/Play button (►) to pause, and the stopwatch to zero. For time less than 5 seconds, use the step button (|►) to increase time by 0.5 second intervals. Record the voltage values in Table 3. After 5 seconds, use the Pause/Play button (►/||) to record the voltage at about 10.0, 15.0, 20.0, and 25.0 seconds.

6. Using equation (5), obtain the charge at each time, and enter in Table 3.

7. Draw a graph between charge on y-axis and time on x-axis. It should look like Fig. 5.

8. Use the known values of resistance and capacitance to calculate the time constant and the maximum charge by using eqn. (2) and eqn. (3), and enter in Table 4.

9. Calculate the charges equal to one time constant, two time constants, and five time constants and enter in Table 4. Compare these with the experimental values using % error. Put your calculation in the table II.

Case-C: Capacitors in Series.

1. Set up the circuit as shown in figure 10.

2. Set the resistance to 100 Ω, each capacitance to 0.05 F, and Battery to 10.0 V.

3. Before charging the capacitor, make sure that it has no charge (the voltmeter reads zero). Otherwise you need to discharge the capacitor first until the voltage across the capacitor becomes zero.

4. Put switch S1 in the ON state and switch S2 to the OFF state.

5. Now calculate the value of the time constant by using the equation for sum of capacitors in series.

6. Start charging the capacitors and note the voltage difference across both capacitors. Note the time it takes for the voltage to reach 63.2 % of Vmax. This is the measured value of time constant. Note this in Table 5.

7. Now charge the capacitors to full charge, and by using proper switching, measure the time for the voltage across them to fall BY 63.2% of Vmax. This is the measured time constant for discharging the capacitors.

8. Compare the measured and calculated values of the time constant for capacitors in series. (Part A: STANDING WAVES ON A STRING Using PhET simulation)

Procedures

1. Build the circuit as shown in Figure 1 using the PhET Simulation Tool.

2. Set the DC Power Source to 12.0 V.

3. Create three resistors 10.0 Ω, 20.0 Ω, and 30.0 Ω. Putting each resistor into the circuit one at a time, measure voltage using the voltmeter and record the values on Table 1. Note that the volt-meter should be parallel with the resistor.

4. With the power source still set at 12.0 V, measure the current of each resistor and record the values on Table 1. The ammeter should be in series with the resistor. You must first cut the circuit and open it with two disconnected ends and then plug in the ammeter. Please refer to “PhET Simulation Tool Instructions for Electric Circuits Labs” for how to measure current.

5. Avoid the common mistake of connecting the ammeter directly to the power supply’s two terminals.

6. Compare the calculated and measured currents in Table 1 and find the percentage difference.

7. Put the 10.0 Ω resistor in the circuit and increase the voltage of the power supply from to using increments. Using the method outlined in step 4, measure the current at each step. Record the voltage and current values in Table 2.

8. Plot the voltage-current curve and find the slope of the line. The slope of the line will be the resistance.

9. Compare the measured with the known values of the resistance values and find the percentage error.

Part G E-34-O KIRCHHOFF’S RULES ONLINE LAB

7/01/2020

 

OBJECTIVE

The purpose of this lab will be to experimentally demonstrate Kirchhoff’s Rules for electrical circuits.

 

EQUIPMENT

PhET interactive simulation tool (Circuit Construction Kit: DC – Virtual Lab):

https://phet.colorado.edu/en/simulation/circuit-construction-kit-dc-virtual-lab

For an introduction on using the PhET Circuit Construction simulation, see: 00-PhET Simulation Tool instructions for Electric Circuits Labs.

 

THEORY (Part A: STANDING WAVES ON A STRING Using PhET simulation)

Electronic circuits that cannot be reduced to simple series of parallel circuits can be analyzed by different methods. As an example, consider the circuit of figure 1. The currents and voltage drops across the resistances cannot be found by a simple application of Ohm’s Law. In this circuit, points A and D are called Junctions, since more than two wires connect there. A closed loop is any path that starts at some point in the circuit, passes through the elements of the circuit, and arrives back at the same point, without passing through any element more than once. There are three such closed loops in the circuit of Figure 1. These are Loop 1: A-B-C-D-A, Loop 2: A-D-E-F-G-A, and Loop 3: B-C-D-E-F-G-A-B. The junctions and loops are used in two Kirchhoff’s rules to analyze the circuit.

KCR- Kirchhoff’s Current Rule: The sum of the currents entering a junction = sum of currents leaving a junction. Or equivalently: the net current entering a junction is zero.

KVR-Kirchhoff’s Voltage Rule: The algebraic sum of the voltage changes around any closed loop is zero.

We would usually know the values of the battery voltages and resistances. As a first step, we label and assign directions (arbitrarily) to the currents in each section of the circuit (i.e. between each junction). We then write the junction equation (assuming a current entering the junction is positive, and leaving the junction is negative) at node D as:

i1 + i3 – i2 = 0 (1)

We now traverse the closed loops in any direction (clockwise or counter-clockwise, the resulting equations are equivalent) and add up all the changes in the voltages and set them to zero, i.e.

ΣΔV = 0 (2)

The voltage change across a resistor is found by Ohm’s Law as

ΔV = I R (3)

The sign of ΔV is positive if we are crossing the resistance in a direction that is against the direction of the current in that resistor, and it is negative if we go across the resistor in the same direction as the current. The ΔV across the battery is positive if we cross it from its negative to its positive side. With these, the equations for the three loops become:

Loop 1 (starting at the point A and going clockwise):

V1 – i1*R1 – i1*R2 + i3*R3 = 0.0 (4)

 

Loop 2 (starting at A and going clockwise):

-i3*R3 – i2*R4 + V2 – i2*R5 = 0.0 (5)

Loop 3 (starting at A, and going clockwise):

+V1 – i1*R1 – i1*R2 – i2*R4 + V2 – i2*R5 = 0.0 (6)

Note that equation (6) is simply the sum of equations (4) and (5), and is therefore not an independent equation. The same would apply to the junction rule applied at node A. So the useful (or independent) number of Junction equations that we can use are one less than the number of junctions, and the Loop equations are one less than the number of loops.

We then simultaneously solve equation (1) and any two out of equations (4), (5) and (6) to obtain the values of the currents i1, i2 and i3. In case any of the currents comes out to be negative, it simply means that we had choses then wrong direction for that current.

 

 

 

 

 

 

 

 

 

 

PROCEDURE (Part A: STANDING WAVES ON A STRING Using PhET simulation)

1 Select five resistors and measure and note their resistances. Label them as R1, R2, … , R5. Select resistors that are in the range of 10.0 Ω to 100.0 Ω.

2 Connect the resistors on the PhET simulation to make the circuit as shown in Figure 1. Attach the two batteries to appropriate points on the circuit. Set their voltages between 6.0 to 10.0 volts each. (The two voltages may or may not be the same). Note the positions of the resistors R1, R2, … R5. Measure the voltages across the batteries and note these as V1 and V2 in the Data Sheet.

3 Using the values of the resistances and battery voltages, calculate the currents i1, i2 and i3 by using the two Kirchhoff’s Rules. Use the same notation and directions of the currents as used in Figure 1. Use the calculated currents to calculate the potential difference across each resistor by using Ohm’s Law.

4 Once the calculations are done, you have an idea of what values to expect. First measure the voltages across each of the resistors and note it.

5 Now measure the currents i1, i2 and i3. For this you would need to break the circuit and insert the ammeter in series with the wires to complete the loop.

6 Calculate the percent errors in the calculated and measured values of the currents and voltages. Check to see if the Kirchhoff’s Junction rule and Loop Rules are verified.

You can also get to the simulations by entering in your browser: Phet, then select Physics. Then select Bending Light, and Geometric Optics simulations.

 

PROCEDURE (Part A: STANDING WAVES ON A STRING Using PhET simulation)

The procedure for all experiments will be to track a laser beam as it reflects or refracts. In the simulations that we will use, we have a laser that can be turned on or off by clicking the red button on it. It can also be moved and rotated. The laser will give a narrow ray of light which we will follow as it reflects or refracts. This can be done for several points in the beam’s path.

 

In most cases, you would need to measure the angle, which is done from the normal to the surface. You can turn on the normal by selecting it in one of the menu boxes on the page. You can measure the angle by using the protractor tool. Complete the Results section at the end.

 

CASE A: Reflection from a Plane Mirror (see figure 1)

1. After opening the simulation, select “INTRO”.

2. Select the material where the laser is as “AIR”, and that on the lower side as “WATER”.

3. Set the laser to any arbitrary angle. Turn on the laser.

4. Use the Protractor to measure the angle of the incident ray and angle of the reflected ray (this is dimmer than the incident ray). (ignore the ray going into the water). Repeat for different angles.

5. Repeat for AIR and GLASS as the materials.

6. Enter the results in Table A, and verify that the angle of incidence = angle of reflection.

CASE B: Refraction (see figure 2)

1. After opening the simulation, select “INTRO”.

2. Select the material where the laser is as “AIR”, and that on the lower side as “WATER”.

3. Set the laser to any arbitrary angle. Turn on the laser.

4. Use the Protractor to measure the angle of the incident ray and angle of the refracted ray (i.e. the one entering the water). (ignore the reflected ray). Repeat for different angles.

5. Repeat for AIR and GLASS as the materials.

6. Repeat with AIR and MYSTERY A as the two materials.

7. Enter the results in Table B, and calculate the refractive indices of water, glass and Mystery A by using equation 1.

 

CASE C: Refraction Again (see figure 7)

1. After opening the simulation, select “PRISM”.

2. From the bottom panel, select the Square. Set Reflections Off. Turn on Normal.

3. Select the Environment as AIR. Select Objects as GLASS.

4. Set the laser to any arbitrary angle, pointing to the square. Turn on the laser.

5. Use the Protractor to measure the angle of the incident ray and angle of the refracted ray (i.e. the one entering and inside the square). Make sure that the ray inside the square does not reflect form the side surface.

6. Use these angles to calculate the refractive index of the material by using equation 1. Repeat with different angles.

7. Repeat for MYSTERY B as the material of the square.

8. Enter the results in Table C.

CASE D: Total Internal Reflection (Part A: STANDING WAVES ON A STRING Using PhET simulation)

1. After opening the simulation, select “INTRO”.

2. Select the material where the laser is as “WATER”, and that on the lower side as “AIR” (i.e. the laser beam is going from water into air)

3. Set the laser to a small angle (i.e. close to the normal). Turn on the laser.

4. Increase the angle slowly and observe the refracted ray. At some angle, the refracted ray will become parallel to the water-air surface. Beyond this point, when the angle is further increased, there is no refracted ray, only a reflected ray. This is Total Internal Reflection. The angle that the incident ray makes at the point at which the refracted ray becomes parallel to the glass surface (i.e. angle of refraction = 90), is called the Critical Angle. Use the Protractor to measure the angle of incidence at this point. Use equation 3 to compare the calculated and measured values of the Critical Angle.

5. Repeat to find the critical angle for the GLASS – AIR interface.

6. Enter the results in Table D.

 

CASE E: Total Internal Reflection Again (see figure 6)

1. After opening the simulation, select “PRISM”.

2. Select the semi-circular object, and bring it to the middle of the screen. Its straight side should be vertical.

3. Select the Environment as Air, and semi-circular object as Glass. Turn on Normal. Turn off Reflections.

4. Turn on the laser. Set the laser to an angle about 40° with the horizontal.

5. Now place the cursor in the object, with left click hold the object and move it (it should not rotate) to a position so that the laser beam entering it is at zero degrees to the surface. This is when the beam is directly over (i.e. parallel to) the normal. It will now be exiting the object from center of the flat side, which is also the center of the circle forming the curved side. Now rotate the Object by holding it from the little thing at its bottom. The object must not move, only rotate. This will rotate it about its center so that the beam is always exiting from the center of the flat side.

6. Keep rotating the object slowly, until the exiting beam is parallel to the flat surface. If you turn it a bit more, the beam will have Total Internal Reflection. Use the protractor to measure the angle on incidence inside the object at the flat surface at the point of Total Internal Reflection. The angle of refraction should be 90°. Use equation 3 to compare the calculated and measured values of the Critical Angle.

7. Repeat for Mystery A. Use the refractive Index found in Case B for calculating the percent error.

8. Enter the results in Table E.

 

CASE F: Refraction Light Ray Shift (see figure 7)

1. After opening the simulation, select “PRISM”.

2. From the bottom panel, select the Square. Set Reflections Off. Turn on Normal.

3. Select the Environment as Air. Select Objects as Glass.

4. Set the laser to any arbitrary angle, pointing to the square. Turn on the laser. The laser beam should come out from the back side.

5. Note (figure out how), the position of the refracted ray coming out of the glass on the other side.

6. Change the material of the Object to “Air”. This will cause the ray to go straight (since refractive indices of environment and square are the same). Note the position of this ray.

7. Measure the distance that the ray shifts when the Object is Air and when it is Glass (figure out how to do this). Enter the results in Table 6.

8. Measure the thickness of the square. Enter all data in Table F.

9. Use equation 6 to calculate the shift, and compare with your measured value.

CASE G: Deviation of light by a prism (see figure 3)

1. After opening the simulation, select “PRISM”.

2. From the bottom panel, select the Triangle (prism). Set Reflections Off. Turn on Normal.

3. Select the Environment as Air. Select Objects as Glass.

4. Set the laser to any arbitrary angle, pointing to the prism. Turn on the laser. The laser beam should come out from the other side.

5. Use the protractor to measure the angle of incidence θi , angle of refraction θr, angle of the prism A , and angle of Deviation δ, and record them in Table G.

6. Calculate the angle of deviation by using equation (4), and compare with measured value. Use the refractive index of glass found in Case C.

 

CASE H: Focal Length of a Convex Lens (see figure 4) (Part A: STANDING WAVES ON A STRING Using PhET simulation)

1. Open the simulation: Geometric Optics.

2. Select Principal Rays and Screen. Select some values of Curvature, Refractive Index and Diameter of the lens.

3. Place the lamp al some position on the principal Axis (the horizontal line passing through the center of the lens).

4. Move the screen until the image becomes a small dot. The image of the object is now in focus on the screen.

5. Select the Ruler, and measure the distance from the center of the lens to the light source. (Measure to the point where the rays join together). This is the Object distance ‘p’. Now measure the image distance ‘q’ from the lens to the screen (to the point where the rays join). You may have to select a pencil or an arrow as the object to do this.

6. Note the data in Table H, and calculate the focal length, ‘f’, of the lens.

7. Repeat for several different positions of the object. Have at least one position where you get a virtual image (i.e. when object is between lens and the focal length).

8. Measure the focal length (this is the distance from lens to the ‘X’ on the Principal Axis.

RESULTS

All values are measured values unless mentioned. Attach at least one image of each case with your report.

Ethical Conduct

(Ethical Conduct) Discuss nursing ethics based on the case study.

Ethical Conduct

Nursing Ethics in the Context of a Case Study

Nursing ethics is crucial in ensuring that patient care aligns with moral principles. A recent case study highlights the importance of ethical considerations in nursing. In this case, a nurse faced a dilemma when a terminally ill patient requested assistance in ending their life. This situation presents various ethical challenges, requiring a thorough understanding of nursing ethics to navigate effectively.

Respect for Autonomy

Firstly, respect for autonomy is a fundamental ethical principle in nursing. Autonomy refers to the patient’s right to make decisions about their own health care. In the case study, the patient expressed a clear desire to end their suffering through euthanasia. Therefore, the nurse must respect this wish while considering legal and professional boundaries. To support the patient’s autonomy, the nurse should ensure the patient fully understands their options and the potential consequences of their decision. (Ethical Conduct)

Beneficence and Non-Maleficence

Beneficence and non-maleficence are also critical in nursing ethics. Beneficence involves promoting the patient’s well-being, while non-maleficence means avoiding harm. In the case study, the nurse faces a conflict between these principles. Assisting the patient in ending their life may be seen as promoting well-being by alleviating suffering. However, it also involves causing harm. The nurse must carefully weigh these principles to determine the best course of action.

Legal and Professional Considerations

Legal and professional considerations also play a significant role in nursing ethics. The nurse must adhere to the laws and regulations governing their practice. In many jurisdictions, euthanasia is illegal, and assisting a patient in ending their life could result in severe legal consequences. Moreover, professional codes of ethics, such as the American Nurses Association’s Code of Ethics, provide guidelines for nurses. These codes often emphasize the importance of preserving life and prohibit actions that intentionally cause death. Thus, the nurse must balance ethical principles with legal and professional obligations. (Ethical Conduct)

Communication and Compassion

Effective communication and compassion are essential in addressing ethical dilemmas. The nurse should engage in open, honest conversations with the patient and their family. This approach helps to understand their perspectives and provide emotional support. By listening to the patient’s concerns and explaining the ethical and legal constraints, the nurse can build trust and provide compassionate care. Additionally, involving other healthcare professionals, such as physicians and ethicists, can offer valuable insights and support in decision-making.

Ethical Decision-Making Frameworks

Applying ethical decision-making frameworks can guide nurses in resolving complex ethical dilemmas. One such framework is the Four-Box Method, which considers medical indications, patient preferences, quality of life, and contextual features. By systematically evaluating these factors, the nurse can make a well-informed decision. In the case study, this approach could help balance the patient’s desire for euthanasia with the ethical, legal, and professional considerations involved.

Conclusion

Nursing ethics require a careful balance of respecting patient autonomy, promoting well-being, avoiding harm, and adhering to legal and professional standards. In the presented case study, the nurse faces a challenging ethical dilemma when a terminally ill patient requests assistance in ending their life. By applying ethical principles, effective communication, and decision-making frameworks, the nurse can navigate this complex situation. This approach ensures that patient care remains compassionate, ethical, and legally compliant.

Engineering Industrial Waste Solutions

(Engineering Industrial Waste Solutions)
Industrial & Hazardous Waste Management
This unit has assessed engineering principles applicable to industrial and hazardous waste management. Steps were evaluated for an adsorption system design using engineering principles and presenting engineering calculations for waste treatment.

The steps in the lesson were accomplished by the required reading of an article describing laboratory adsorption tests for lead and zinc removal. The lesson used the article’s data combined with engineering principles to design a prototype lead treatment system, and a required article presented a novel method for reducing leather tanning waste.

For this assignment, prepare a PowerPoint presentation that assesses engineering principles applicable to industrial and hazardous waste management by evaluating steps for an adsorption system design using engineering principles and presenting engineering calculations for waste treatment.

Specifically address the following items in your PowerPoint presentation.

  • Provide a title and introduction.
  • Summarize the Durga, Ramesh, Rose, and Muralidharan Required Unit Resources article.
  • List the steps required for design of a prototype adsorption system.
  • From Required Unit Resources, use the Yusuff and Olateju article’s equation (7) for the Radke-Prausnitz isotherm to evaluate qe for a Ce lead concentration of 10 mg/L. Show your calculation.
  • Explain how your value of qe determined from the equation compares to the value in Yusuff and Olateju’s article exhibit 10a. Do you think there is an error in the equation? Explain.
  • In the unit lesson, if the prototype’s wastewater flow is 500 gpd instead of 100 gpd and the influent lead concentration is still 10 mg/L, what would be the lead inflow rate in units of grams per day? Show your calculation.
  • Provide a summary of your PowerPoint information.

Your PowerPoint presentation must be at least 15 slides in length with a title slide and reference slide (title and reference slides do not count toward the minimum slide count). You should utilize at least the two Required Unit Resources: the Durga et al. and the Yusuff and Olateju articles. Ensure you refer to the unit lesson as you are creating your PowerPoint presentation.

Please adhere to APA Style when creating citations and references for this assignment. Do not include slide notes in your presentation. Be sure to use fonts that are large enough to view from a distance. This includes any fonts within images that you use. Be sure to cite and reference all information and images.

Reading Assignment OSHA’s Field Operations Manual (FOM): Chapter 7: Post-Citation Procedures and Abatement Verification Occupational Safety and Health Administration. (2011). Field Operations Manual. Retrieved from

https://www.osha.gov/OshDoc/Directive_pdf/CPL_02-00-159.pdf

Unit Lesson When an Occupational Safety and Health Administration (OSHA) inspection results in citations and penalties, employers can react in many different ways, including disbelief, anger, and confusion about what is required. However, there are some specific requirements that all employers must follow, and some options that are available under the Act. Employees also have some rights after the inspection is complete and citations and penalties have been issued. Many discussions about what can be done after an inspection has been completed are limited to employers, and the rights of employees are not considered.

The OSHA inspection process is supposed to be transparent to employees. This means that the employer has to post any citations that were issued by OSHA. The citations must be posted in the location where the violation(s) occurred, or nearby, and must remain posted for at least 3 days or until the violation(s) have been abated, whichever is longer. Some employers mistakenly believe that they do not have to post the citation notice if they are going to contest the citations. This belief is incorrect. The citation notice must be posted whether the employer is going to contest the citations or not. These posting requirements are specified in 29 CFR 1903.16. Employers can be further cited and penalized if they fail to post a copy of the original citations. Additionally, any abatement certification documents, abatement plans, progress reports, and a notice of informal conference made by the employer to OSHA

concerning the citations must be posted so employees can see the responses. The Act provides both employers and employees with certain rights after the completion of an inspection. These rights are designed to ensure that both the employer and employee have the ability to contest citations and penalties that they believe are unfair. There are several processes available ranging from informal discussions to formal legal proceedings. The employer may decide to simply accept and abate all the citations and pay the proposed penalties. If the

UNIT IV STUDY GUIDE

(OSHA Inspection Legal Procedures)

Employer Rights and Responsibilities after an OSHA Inspection

(US Dept. of Labor, 2011)

Employer chooses this option, they must complete the abatement prior to the abatement date specified in the Notice of Citations and Penalties and pay the penalty(ies). 29 CFR 1903.20 provides a process for both employers and employees (or their representative) to request an informal conference with the area director, or their representative. An employee may desire to have an informal conference because they believe their safety or health concerns were not adequately addressed by the OSHA inspection. An employer may desire the informal conference because they believe the citations and penalties were too harsh, because they do not understand some part of the citation or penalty, or to highlight some additional information about their health and safety program(s) to the area director that they believe may mitigate the severity of the citations and penalties. In some cases, the area director may agree to reduce the severity and/or amount of the penalty(ies). If this occurs, an informal settlement agreement may be reached and further litigation avoided.​

It should be noted that employees, or their representatives have the right to participate in any informal conference. This is the reason a notice of an informal conference must be posted in or near the area where citations occurred. Many health and safety experts recommend that an employer always request an informal conference after citations and penalties are issued. Employers must remember that the informal conference does not delay the 15 working days that the employer has to file a notice of contest. Therefore, the employer must schedule the informal conference early enough to allow time to file a Notice of Contest, if necessary. If the employer does not file a Notice to Contest within 15 working days, the citation becomes a final order. This means that the area director can no longer change the seriousness of citations or the penalties because they have become final orders.​

The ability of the employer or employee to formally contest citations, penalties, and abatement dates is extremely important for ensuring due process is provided. The contest process means the employer or employee does not have to accept the views of the compliance officer(s) and the area director without any ability to defend themselves or challenge what is perceived as an inadequate or over reactive response to an employee complaint. An employer or employee does not have to contest every citation and penalty. In fact, in most cases, only a portion of the citations and penalties are challenged. Once a formal notice to contest is filed, the case is in litigation and the area director cannot take any additional actions until the case is heard by an administrative law judge (ALJ) assigned to the case.​

There are many federal agencies that use ALJs. The ALJs that hear contested OSHA citations are from the Occupational Safety and Health Review Commission (OSHRC). The OSHRC was created along with OSHA after the Act was passed. It should be noted that the OSHRC is an independent organization, separate from OSHA and the Department of Labor. This separation was by design to make sure there is no undue influence over the OSHRC. This helps ensure the hearings are impartial. We will study the OSHRC and ALJs in more detail in Units VI and VII.​

The Citation and Notification of Penalty document will specify state abatement dates for each citation. The dates are set by the compliance officer performing the inspection based on his/her best estimate of the time required to complete the abatement. Employers have the right to formally petition for an extended abatement date if they believe they will not be able to meet the original date. 29CFR 1903.1 contains specific requirements for filing a Petition for Modification of Abatement Date (PMA).​

The final document OSHA requires for citations is abatement certification. Abatement certification is required for all citations that have become final orders, except “quick-fix” items that were corrected during the inspection. 29CFR 1903.19 contains specific requirements for abatement certifications. The regulation includes some more extensive documentation for more serious violations. The Citation and Notification of Penalty will typically specify which violations require additional certification. The area director may require an abatement plan to be submitted for some violations, especially if the abatement is complicated or may take an extended period of time. The area director may also require the abatement plan to include interim measures to protect employees during the extended abatement process. If an abatement plan is required, the employer may be required to periodically submit progress reports.
