Nursing Elites

1. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?

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

Correct answer: A

Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, the nurse should closely monitor the serum potassium level. Erythropoietin therapy can increase red blood cell production, leading to a higher demand for potassium. Monitoring potassium levels is crucial to prevent hyperkalemia, a potential risk associated with this therapy. Hemoglobin level (Choice B) is important to assess the effectiveness of erythropoietin therapy, but monitoring potassium levels takes precedence due to the risk of hyperkalemia. White blood cell count (Choice C) and serum calcium level (Choice D) are not directly affected by erythropoietin therapy in the context of chronic kidney disease.

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

• A. Prothrombin time (PT)
• B. Hemoglobin level
• C. International Normalized Ratio (INR)
• D. Serum sodium level

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). The INR should be closely monitored in a client prescribed warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range for anticoagulation, reducing the risk of bleeding or clotting complications. Prothrombin time (A) is used to calculate the INR and monitor the effectiveness of warfarin therapy. Hemoglobin level (B) is important but not the primary lab value to monitor when a client is on warfarin. Serum sodium level (D) is not directly related to monitoring warfarin therapy.

3. The nurse is caring for a client with a history of atrial fibrillation who is receiving warfarin (Coumadin). Which laboratory value should be closely monitored?

• A. Serum potassium level
• B. Prothrombin time (PT)
• C. International Normalized Ratio (INR)
• D. Serum sodium level

Correct answer: C

Rationale: The correct answer is C, 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 for anticoagulation to prevent complications such as bleeding or clotting. Choices A, B, and D are incorrect. While monitoring electrolyte levels like serum potassium and sodium is important in overall client care, they are not specific to monitoring the effects of warfarin therapy. Prothrombin time (PT) is a component of INR and helps in monitoring warfarin therapy, but INR gives a standardized result that is independent of the laboratory method used, making it the preferred choice for monitoring warfarin therapy.

4. A client with cirrhosis is admitted with jaundice and ascites. Which assessment finding requires immediate intervention?

• A. Peripheral edema
• B. Confusion and altered mental status
• C. Yellowing of the skin
• D. Increased abdominal girth

Correct answer: B

Rationale: Confusion and altered mental status are the most critical assessment findings in a client with cirrhosis. These symptoms may indicate hepatic encephalopathy, a serious complication that requires immediate intervention. Yellowing of the skin (jaundice) is a common manifestation of cirrhosis and does not necessitate immediate intervention. Peripheral edema and increased abdominal girth are associated with fluid retention in cirrhosis but are not as urgent as addressing altered mental status and confusion.

5. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which assessment finding is most concerning?

• A. INR of 3.5
• B. Prothrombin time (PT) of 15 seconds
• C. Headache
• D. Blood pressure of 140/90 mmHg

Correct answer: C

Rationale: The correct answer is C. A headache in a client with a history of atrial fibrillation receiving warfarin (Coumadin) is concerning as it may indicate bleeding, which requires immediate assessment and intervention. Headaches can be a symptom of increased intracranial pressure due to bleeding, especially in patients on anticoagulants. Options A and B are within acceptable ranges for a client on warfarin therapy, indicating that the medication is effectively managing the clotting times. Option D, a blood pressure of 140/90 mmHg, while elevated, is not directly related to the client's condition of atrial fibrillation and warfarin therapy.
