Nursing Elites

1. A client with chronic kidney disease (CKD) is scheduled for a hemodialysis session. Which laboratory value should the nurse report to the healthcare provider before the procedure?

• A. Serum potassium of 5.5 mEq/L
• B. Blood urea nitrogen (BUN) of 40 mg/dl
• C. Serum potassium of 6.0 mEq/L
• D. Serum creatinine of 2.5 mg/dl

Correct answer: C

Rationale: A serum potassium level of 6.0 mEq/L is dangerously high for a client with chronic kidney disease (CKD) scheduled for hemodialysis. High potassium levels can lead to cardiac complications such as arrhythmias. Therefore, it is crucial to report this value to the healthcare provider before the procedure to prevent any potential serious complications. Choices A, B, and D are not as critical in the context of preparing for a hemodialysis session. Serum potassium levels above 6.0 mEq/L require immediate attention to ensure patient safety.

2. Which nursing intervention is most important when caring for a client with myasthenia gravis?

• A. Encourage the client to rest frequently.
• B. Administer medication 30 minutes before meals.
• C. Maintain a patent airway.
• D. Monitor for signs of respiratory infection.

Correct answer: C

Rationale: Maintaining a patent airway is crucial for clients with myasthenia gravis because muscle weakness can affect the muscles responsible for breathing, potentially leading to respiratory compromise. Encouraging rest, administering medication, and monitoring for respiratory infections are important aspects of care but do not take precedence over ensuring a patent airway for adequate oxygenation.

3. A client with chronic kidney disease (CKD) is scheduled for a renal biopsy. Which laboratory value is most concerning?

• A. Serum potassium of 5.5 mEq/L
• B. Serum creatinine of 1.5 mg/dl
• C. Serum creatinine of 2.5 mg/dl
• D. White blood cell count of 8,000/mm3

Correct answer: C

Rationale: A serum creatinine level of 2.5 mg/dl is the most concerning laboratory value in a client with chronic kidney disease scheduled for a renal biopsy. An elevated serum creatinine level indicates impaired kidney function, which is critical information before performing a renal biopsy. Option A (Serum potassium of 5.5 mEq/L) may be concerning for hyperkalemia but is not directly related to the renal biopsy procedure. Option B (Serum creatinine of 1.5 mg/dl) is within normal limits, suggesting relatively normal kidney function. Option D (White blood cell count of 8,000/mm3) is within the normal range and not directly related to the renal biopsy procedure or CKD management.

4. A client with a history of chronic heart failure is admitted with shortness of breath. Which laboratory value should be closely monitored?

• A. Serum sodium level
• B. Serum potassium level
• C. Serum creatinine level
• D. Hemoglobin level

Correct answer: B

Rationale: Corrected Rationale: In a client with chronic heart failure, serum potassium levels should be closely monitored to assess for hyperkalemia, which can worsen heart failure. Monitoring serum sodium levels is not the priority in this case. Serum creatinine level monitoring is more related to kidney function than heart failure. Hemoglobin levels are important but not the primary concern when assessing heart failure exacerbation.

5. A client with cirrhosis is admitted with hepatic encephalopathy. Which laboratory value is most concerning?

• A. Serum ammonia level of 100 mcg/dl
• B. Bilirubin level of 3.0 mg/dl
• C. Prothrombin time of 18 seconds
• D. Serum sodium level of 135 mEq/L

Correct answer: A

Rationale: A serum ammonia level of 100 mcg/dl is most concerning in a client with hepatic encephalopathy. Elevated serum ammonia levels indicate significant liver dysfunction and an increased risk of worsening encephalopathy. Bilirubin level and prothrombin time are important in assessing liver function, but in the context of hepatic encephalopathy, elevated ammonia levels take precedence as they directly contribute to neurological symptoms. Serum sodium level, though important, is not the primary concern when managing hepatic encephalopathy.
