Nursing Elites

1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

• A. International Normalized Ratio (INR)
• B. Prothrombin time (PT)
• C. Serum sodium level
• D. Hemoglobin level of 12 g/dl

Correct answer: A

Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client receiving warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range to prevent both bleeding and clotting events. Choices B, C, and D are incorrect because while PT is used to monitor warfarin therapy, INR is a more precise indicator of therapeutic levels. Serum sodium level and hemoglobin level are not directly related to monitoring warfarin therapy.

2. A client with chronic obstructive pulmonary disease (COPD) is experiencing shortness of breath and has a prescription for oxygen therapy. What is the maximum amount of oxygen the nurse should administer without a healthcare provider's order?

• A. 2 liters per minute
• B. 4 liters per minute
• C. 6 liters per minute
• D. 8 liters per minute

Correct answer: B

Rationale: The correct answer is 4 liters per minute. Without a healthcare provider's order, the nurse should administer a maximum of 4 liters per minute of oxygen to prevent carbon dioxide retention in COPD clients. Higher flow rates can lead to oxygen toxicity and worsen the client's condition. Choices A, C, and D exceed the safe limit for oxygen administration without a healthcare provider's order.

3. A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which laboratory value requires immediate intervention?

• A. Serum potassium of 6.5 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 2.0 mg/dL
• D. Blood glucose of 150 mg/dL

Correct answer: A

Rationale: A serum potassium level of 6.5 mEq/L is most concerning in a client with CKD as it indicates severe hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias. Serum sodium levels within the normal range (135 mEq/L) are not immediately concerning. Serum creatinine of 2.0 mg/dL may indicate impaired kidney function but does not require immediate intervention for hyperkalemia. Blood glucose of 150 mg/dL is within normal limits and does not directly correlate with hyperkalemia in this scenario.

4. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which finding indicates the need for immediate intervention?

• A. Use of accessory muscles
• B. Oxygen saturation of 94%
• C. Carbon dioxide level of 45 mmHg
• D. Respiratory rate of 20 breaths per minute

Correct answer: C

Rationale: A carbon dioxide level of 45 mmHg is concerning in a client with COPD receiving supplemental oxygen, as it may indicate carbon dioxide retention and requires immediate intervention. Options A, B, and D are not the priority findings in this scenario. While the use of accessory muscles, an oxygen saturation of 94%, and a respiratory rate of 20 breaths per minute are important to monitor in a client with COPD, they do not indicate an immediate need for intervention like an elevated carbon dioxide level does.

5. During a clinic visit, a client with a kidney transplant asks, 'What will happen if chronic rejection develops?' Which response is best for the nurse to provide?

• A. Dialysis would need to be resumed if chronic rejection becomes a reality.
• B. Immunosuppressive therapy would be intensified.
• C. A second transplant would be scheduled immediately.
• D. We would monitor your kidney function closely.

Correct answer: A

Rationale: The best response for the nurse to provide is that dialysis would need to be resumed if chronic rejection becomes a reality. Chronic rejection of a transplanted kidney can lead to kidney failure, necessitating the need for dialysis until another transplant is possible. Choice B is incorrect because although immunosuppressive therapy may be adjusted, the immediate concern is the potential need for dialysis. Choice C is incorrect because scheduling a second transplant immediately is not typically the first step following chronic rejection. Choice D is also incorrect as close monitoring of kidney function is essential but does not address the immediate need for dialysis if chronic rejection occurs.
