Nursing Elites

1. A client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which laboratory value should the nurse report to the healthcare provider immediately?

• A. Serum potassium of 5.5 mEq/L
• B. Serum calcium of 8 mg/dL
• C. Serum creatinine of 2.0 mg/dL
• D. White blood cell count of 10,000/mm³

Correct answer: A

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to serious cardiac arrhythmias, especially during hemodialysis. Serum calcium, serum creatinine, and white blood cell count, while important, do not pose immediate life-threatening risks like hyperkalemia.

2. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be closely monitored?

• A. Serum potassium level
• B. Hemoglobin level
• C. White blood cell count
• D. Serum calcium level

Correct answer: A

Rationale: The correct answer is A: Serum potassium level. When a client with chronic kidney disease is receiving erythropoietin therapy, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant in assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical in this scenario.

3. While removing staples from a male client's postoperative wound site, the nurse observes that the client's eyes are closed and his face and hands are clenched. The client states, 'I just hate having staples removed.' After acknowledging the client's anxiety, what action should the nurse implement?

• A. Attempt to distract the client with general conversation
• B. Administer a pain medication
• C. Continue with the procedure while reassuring the client
• D. Stop the procedure and notify the healthcare provider

Correct answer: A

Rationale: In this situation, the nurse should attempt to distract the client with general conversation. Distracting the client can help reduce anxiety and make the procedure less stressful. Administering pain medication (choice B) is not appropriate as the client's discomfort is related to anxiety, not physical pain. Continuing with the procedure while reassuring the client (choice C) may not address the client's anxiety effectively. Stopping the procedure and notifying the healthcare provider (choice D) is not necessary at this point since the client's anxiety can be managed by attempting to distract him.

4. A client with a history of chronic kidney disease (CKD) is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?

• A. Serum potassium level
• B. White blood cell count
• C. Hemoglobin level
• D. Serum calcium level

Correct answer: A

Rationale: The correct answer is A: Serum potassium level. In a client receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of hyperkalemia. Erythropoietin can stimulate red blood cell production, leading to an increased demand for potassium. Monitoring potassium levels helps prevent complications associated with hyperkalemia. Choices B, C, and D are incorrect because erythropoietin therapy specifically impacts potassium levels, not white blood cell count, hemoglobin level, or serum calcium level.

5. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?

• A. Low bioavailability
• B. Rapid onset of action
• C. Short half-life
• D. Narrow therapeutic index

Correct answer: D

Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.
