Nursing Elites

1. A nurse reviews laboratory results for a client with glomerulonephritis. The client’s glomerular filtration rate (GFR) is 40 mL/min as measured by a 24-hour creatinine clearance. How should the nurse interpret this finding? (Select all that apply.)

• A. Excessive GFR
• B. Reduced GFR
• C. Fluid retention and risks for hypertension
• D. Pulmonary edema

Correct answer: B

Rationale: A GFR of 40 mL/min indicates a reduced glomerular filtration rate. In a healthy adult, the normal GFR ranges between 100 and 120 mL/min. A GFR of 40 mL/min signifies a significant reduction, leading to fluid retention and risks for hypertension and pulmonary edema due to excess vascular fluid. Choices A, C, and D are incorrect. Choice A is incorrect as a GFR of 40 mL/min is not excessive but rather reduced. Choices C and D do not directly address the interpretation of GFR but instead describe potential consequences of a reduced GFR.

2. The client with chronic renal failure is being taught about the importance of fluid restrictions. Which of the following statements by the client indicates that the teaching has been effective?

• A. I can drink as much fluid as I want, as long as I take my medication.
• B. I will need to limit my fluid intake to prevent fluid overload.
• C. I can drink as much water as I want, as long as I limit other fluids.
• D. I will need to drink only when I am thirsty.

Correct answer: B

Rationale: The correct answer is B: 'I will need to limit my fluid intake to prevent fluid overload.' In chronic renal failure, fluid restrictions are crucial to prevent fluid overload and further damage to the kidneys. Option A is incorrect as unrestricted fluid intake can worsen the condition. Option C is also incorrect as total fluid intake needs to be restricted, not just other fluids. Option D is not ideal because thirst may not accurately reflect the body's fluid needs in chronic renal failure.

3. A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 62, PaCO2 59, and HCO3. Which statement describes the most likely cause of the simultaneous increase in both the PaO2 and the PaCO2?

• A. The hypercapnia resulted from the rapid respirations.
• B. The hypoxic drive was reduced by the oxygen therapy.
• C. The client had a pneumothorax which restricted ventilation.
• D. The client had a pulmonary embolism that reduced perfusion.

Correct answer: B

Rationale: In patients with COPD, oxygen therapy can reduce the hypoxic drive, which is the primary stimulus for breathing in these individuals. By providing supplemental oxygen, the hypoxic drive is diminished, resulting in decreased respiratory effort. As a consequence, the PaO2 may increase due to the supplemental oxygen, but this can lead to a decrease in the respiratory drive and subsequent retention of carbon dioxide, causing an increase in PaCO2 levels. Option A is incorrect because rapid respirations would typically lower PaCO2 levels. Option C is incorrect as a pneumothorax would lead to impaired gas exchange and decreased PaO2 levels without necessarily affecting PaCO2 levels. Option D is incorrect as a pulmonary embolism would typically result in ventilation-perfusion mismatch and decreased PaO2 levels without directly impacting PaCO2 levels.

4. The best indicator that the client has learned how to give an insulin self-injection correctly is when the client can:

• A. Perform the procedure safely and correctly.
• B. Critique the nurse's performance of the procedure.
• C. Explain all steps of the procedure correctly.
• D. Correctly answer a post-test about the procedure.

Correct answer: A

Rationale: The best indicator of learning is the ability to perform the procedure safely and correctly, demonstrating skill acquisition. Choice A is correct because the client's ability to perform the insulin self-injection safely and correctly shows practical understanding and application of the skill. Choice B is incorrect because critiquing the nurse's performance does not necessarily demonstrate the client's ability to carry out the procedure themselves. Choice C is incorrect as merely explaining the steps verbally does not confirm the client's practical execution of the task. Choice D is also incorrect as answering a post-test does not directly assess the client's ability to physically perform the insulin self-injection.

5. A nurse teaches a client who is recovering from a nephrectomy secondary to kidney trauma. Which statement should the nurse include in this client’s teaching?

• A. Since you only have one kidney, a salt and fluid restriction is required.
• B. Your therapy will include hemodialysis while you recover.
• C. Medication will be prescribed to control your high blood pressure.
• D. You need to avoid participating in contact sports like football.

Correct answer: D

Rationale: Clients with one kidney need to avoid contact sports because the kidneys are easily injured. The client will not be required to restrict salt and fluids, end up on dialysis, or have new hypertension because of the nephrectomy.
