Nursing Elites

1. The nurse is teaching the main principles of hemodialysis to a client with chronic kidney disease. Which statement by the client indicates a need for further teaching by the nurse?

• A. My sodium level changes due to the movement from the blood into the dialysate.
• B. Dialysis works by the movement of wastes from higher to lower concentration.
• C. Extra fluid can be pulled from the blood by osmosis.
• D. The dialysate is similar to blood but without any toxins.

Correct answer: B

Rationale: The correct answer is B because dialysis works by the movement of solutes from an area of higher concentration to an area of lower concentration, which is known as diffusion. The other statements are accurate: A correctly describes the movement of sodium during hemodialysis, C explains the removal of excess fluid by osmosis, and D highlights the purpose of the dialysate in removing toxins from the blood.

2. A patient has a serum potassium level of 2.7 mEq/L. The patient’s provider has determined that the patient will need 200 mEq of potassium to replace serum losses. How will the nurse caring for this patient expect to administer the potassium?

• A. As a single-dose 200 mEq oral tablet
• B. As an intravenous bolus over 15 to 20 minutes
• C. In an intravenous solution at a rate of 10 mEq/hour
• D. In an intravenous solution at a rate of 45 mEq/hour

Correct answer: C

Rationale: For a patient with severe hypokalemia with a serum potassium level of 2.7 mEq/L requiring 200 mEq of potassium replacement, the appropriate route of administration would be intravenous. Potassium chloride should be administered slowly to prevent adverse effects; therefore, the correct option is to administer the potassium in an intravenous solution at a rate of 10 mEq/hour. Choices A and B are incorrect because potassium should not be given as a single-dose oral tablet or as an intravenous bolus over a short period of time due to the risk of adverse effects. Choice D is also incorrect as the rate of 45 mEq/hour exceeds the recommended maximum infusion rate for adults with a serum potassium level greater than 2.5 mEq/L, which is 10 mEq/hour.

3. A client in a physician’s office has just made an appointment for an exercise stress test. The client should be instructed to:

• A. Wear sweatpants and a heavy sweatshirt
• B. Eat a small meal just before the procedure
• C. Wear comfortable rubber-soled shoes such as sneakers
• D. Avoid consuming caffeine for 30 minutes before the procedure

Correct answer: C

Rationale: The client should wear comfortable rubber-soled shoes, such as sneakers, for the exercise stress test. This choice ensures safety and stability during the procedure. Wearing sweatpants and a heavy sweatshirt (Choice A) would not be appropriate as the client needs to wear light, loose, comfortable clothing. Eating a small meal just before the procedure (Choice B) could lead to discomfort during the test. Avoiding caffeine for 30 minutes before the procedure (Choice D) is not a specific instruction related to the attire or preparation for the test.

4. The healthcare provider is unable to palpate the client's left pedal pulses. Which of the following actions should the healthcare provider take next?

• A. Auscultate the pulses with a stethoscope.
• B. Call the physician.
• C. Use a Doppler ultrasound device.
• D. Inspect the lower left extremity.

Correct answer: C

Rationale: When pedal pulses are not palpable, using a Doppler ultrasound device is the appropriate next step to locate the pulse. Auscultating the pulses with a stethoscope (Choice A) is used for assessing blood flow in arteries above the clavicle, not for pedal pulses. Calling the physician (Choice B) may be necessary at a later stage, but initially, using a Doppler ultrasound device to locate the pulse is more appropriate. Inspecting the lower left extremity (Choice D) can provide visual information but will not help in locating the pedal pulses, making it a less suitable option.

5. During an interview with a client planning elective surgery, the client asks the nurse, 'What is the advantage of having a preferred provider organization insurance plan?' Which response is best for the nurse to provide?

• A. Neither plan allows the selection of healthcare providers or hospitals.
• B. There are fewer healthcare providers to choose from than in an HMO plan.
• C. An individual may select healthcare providers from outside of the PPO network.
• D. An individual can become a member of a PPO without belonging to a group.

Correct answer: C

Rationale: The best response for the nurse to provide is option C, as it highlights a key advantage of a preferred provider organization (PPO) insurance plan. By stating that an individual may select healthcare providers from outside of the PPO network, the nurse emphasizes the flexibility and freedom of choice that PPO plans offer. This feature allows individuals to seek care from providers who are not part of the PPO network, albeit at a higher cost. Option A is incorrect because both PPO and HMO plans allow the selection of healthcare providers, although with different restrictions. Option B is incorrect as PPO plans typically offer a larger selection of healthcare providers compared to HMO plans. Option D is incorrect as membership in a PPO usually requires affiliation with a group, such as through employment or membership in an organization.
