Nursing Elites

1. 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.

2. A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which laboratory value is most concerning?

• 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 concerning in a client with CKD as it indicates hyperkalemia, which requires immediate intervention to prevent cardiac complications. Hyperkalemia can lead to life-threatening arrhythmias, particularly in patients with impaired kidney function. Serum sodium, creatinine, and blood glucose levels, while important, are not as acutely dangerous as severe hyperkalemia in this context.

3. The nurse is caring for a client with a chest tube in place following a pneumothorax. Which finding requires immediate intervention?

• A. Oxygen saturation of 95%
• B. Crepitus around the insertion site
• C. Subcutaneous emphysema
• D. Drainage of 50 ml per hour

Correct answer: C

Rationale: Subcutaneous emphysema requires immediate intervention in a client with a chest tube following a pneumothorax as it can indicate a pneumothorax recurrence or air leak. Oxygen saturation of 95% is within the normal range and does not require immediate intervention. Crepitus around the insertion site can be expected post-procedure and may not necessitate immediate action. Drainage of 50 ml per hour is a normal finding and does not raise immediate concerns.

4. When planning care for a 10-year-old child with pneumonia receiving oxygen at 5l/min per nasal cannula, what principle of oxygen administration should the nurse consider?

• A. Avoid administration of oxygen at high levels for extended periods.
• B. Increase oxygen flow rate if the child is still tachypneic.
• C. Reduce oxygen levels gradually after symptoms improve.
• D. Humidify the oxygen to prevent drying of mucous membranes.

Correct answer: A

Rationale: The correct principle of oxygen administration to consider is to avoid administering oxygen at high levels for extended periods. High levels of oxygen for prolonged periods can lead to oxygen toxicity, especially in pediatric patients. Increasing the oxygen flow rate based on tachypnea may not be necessary and can potentially lead to oxygen toxicity. Gradually reducing oxygen levels after symptoms improve may compromise the child's oxygenation. While humidifying oxygen is important to prevent drying of mucous membranes, the primary concern in this case is to avoid high oxygen levels for an extended duration to prevent oxygen toxicity.

5. A client with hypertension receives a prescription for enalapril, an angiotensin-converting enzyme inhibitor. What instruction should the nurse include in the medication teaching plan?

• A. Increase intake of potassium-rich foods
• B. Report increased bruising or bleeding
• C. Stop medication if a cough develops
• D. Limit intake of leafy green vegetables

Correct answer: B

Rationale: The correct answer is B: 'Report increased bruising or bleeding.' Enalapril, an ACE inhibitor, can lead to thrombocytopenia, a condition characterized by a low platelet count, which increases the risk of bruising and bleeding. Instructing the client to report any signs of increased bruising or bleeding is crucial for monitoring and managing this potential side effect. Choices A, C, and D are incorrect: A - Increasing potassium-rich foods is not directly related to the side effects of enalapril. C - Developing a cough is a common side effect of ACE inhibitors, but it does not warrant stopping the medication unless advised by a healthcare provider. D - Limiting intake of leafy green vegetables is not necessary with enalapril unless specifically instructed by a healthcare provider for individual reasons.
