Nursing Elites

1. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

2. A client with hyperkalemia is receiving insulin and glucose. Which laboratory value should the nurse monitor closely?

• A. Monitor the client's blood glucose level.
• B. Monitor the client's sodium level.
• C. Monitor the client's calcium level.
• D. Monitor the client's potassium level.

Correct answer: D

Rationale: The correct answer is to monitor the client's potassium level. When administering insulin and glucose in hyperkalemia, the aim is to shift potassium from the bloodstream into the cells, lowering elevated levels. Therefore, monitoring potassium levels closely is essential to prevent hypokalemia or further complications. Monitoring blood glucose levels (Choice A) is important but not the priority in this scenario. Monitoring sodium (Choice B) and calcium levels (Choice C) is not directly related to the treatment of hyperkalemia with insulin and glucose.

3. A client with cirrhosis and ascites asks about fluid restriction. What is the nurse’s best response?

• A. Increase the client's fluid intake gradually.
• B. Restrict oral fluids to 1500 ml per day.
• C. Explain the importance of following a low-sodium diet.
• D. Increase dietary protein to reduce fluid retention.

Correct answer: B

Rationale: The correct answer is B: 'Restrict oral fluids to 1500 ml per day.' In clients with cirrhosis and ascites, fluid restriction is essential to prevent fluid overload, which can worsen symptoms of liver failure. Option A is incorrect because increasing fluid intake would exacerbate the issue of fluid overload. Option C, while important, is not the best initial response to the client's question about fluid restriction. Option D is incorrect as increasing dietary protein does not directly address fluid restriction in clients with cirrhosis and ascites.

4. A client is receiving IV antibiotic therapy for sepsis. Which assessment finding indicates that the client's condition is improving?

• A. Urine output increases to 25 mL/hour
• B. Client reports feeling less fatigued
• C. Heart rate decreases from 120 to 110 beats per minute
• D. White blood cell count decreases from 15,000 to 9,000/mm3

Correct answer: D

Rationale: The correct answer is D. A decrease in white blood cell count indicates that the infection is responding to treatment, making this the most objective indicator of improvement in a client with sepsis. Choices A, B, and C are subjective indicators and may not always directly correlate with the resolution of the underlying infection. While an increase in urine output, a client reporting feeling less fatigued, and a decrease in heart rate are positive signs, they are not as specific or directly related to the resolution of the infection as a decrease in white blood cell count.

5. When taking a health history, which information collected by the nurse correlates most directly to a diagnosis of chronic peripheral arterial insufficiency?

• A. Reports of leg cramping at rest
• B. Family history of heart disease
• C. Current use of beta-blockers
• D. History of intermittent claudication

Correct answer: D

Rationale: Corrected Rationale: Intermittent claudication, or pain in the legs while walking that is relieved by rest, is a classic symptom of peripheral arterial insufficiency. Other factors such as a family history or medication use may contribute to cardiovascular health, but claudication is the most specific indicator. Leg cramping at rest is more indicative of conditions like peripheral neuropathy or deep vein thrombosis. Family history of heart disease and current use of beta-blockers are relevant to overall cardiovascular health, but they are not as directly related to chronic peripheral arterial insufficiency as intermittent claudication.
