Nursing Elites

1. The nurse discovers that an elderly client with no history of cardiac or renal disease has an elevated serum magnesium level. To further investigate the cause of this electrolyte imbalance, what information is most important for the nurse to obtain from the client's medical history?

• A. Frequency of laxative use for chronic constipation
• B. Dietary intake of magnesium-rich foods
• C. Use of magnesium-containing supplements
• D. History of alcohol use

Correct answer: A

Rationale: The correct answer is A. Frequent use of magnesium-containing laxatives can lead to hypermagnesemia, particularly in elderly clients. Option B, dietary intake of magnesium-rich foods, may contribute to elevated serum magnesium levels but is less likely the cause in this scenario. Option C, the use of magnesium-containing supplements, can also contribute to hypermagnesemia but is not as common in elderly clients without a history of using such supplements. Option D, history of alcohol use, is less relevant to the development of elevated serum magnesium levels compared to laxative use for chronic constipation.

2. 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.

3. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value requires immediate intervention?

• A. Serum potassium of 5.5 mEq/L
• B. Serum creatinine of 2.5 mg/dL
• C. Hemoglobin of 10 g/dL
• D. White blood cell count of 10,000/mm³

Correct answer: A

Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client receiving erythropoietin therapy as it indicates hyperkalemia, requiring immediate intervention. High potassium levels can lead to severe cardiac arrhythmias and must be addressed promptly. The other laboratory values, though abnormal, do not present immediate life-threatening risks as hyperkalemia does.

4. The nurse is caring for a client with diabetic ketoacidosis (DKA). Which intervention is most important?

• A. Administer insulin as prescribed.
• B. Monitor the client's urine output.
• C. Assess the client's level of consciousness.
• D. Obtain an arterial blood gas (ABG) sample.

Correct answer: A

Rationale: Administering insulin is the most crucial intervention in managing diabetic ketoacidosis. Insulin helps reduce blood glucose levels and correct metabolic acidosis, which are the primary issues in DKA. Monitoring urine output (Choice B) is important but not as critical as administering insulin. Assessing the client's level of consciousness (Choice C) is essential but does not directly address the underlying cause of DKA. Obtaining an arterial blood gas sample (Choice D) can provide valuable information but is not as urgent as administering insulin to address the immediate metabolic imbalance.

5. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which assessment finding requires immediate intervention?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 24 breaths per minute
• C. Use of accessory muscles
• D. Inspiratory crackles

Correct answer: C

Rationale: The correct answer is C: Use of accessory muscles. In a client with COPD and pneumonia, the use of accessory muscles indicates increased work of breathing and may signal respiratory failure. Immediate intervention is necessary to prevent further deterioration of the respiratory status. Choice A, an oxygen saturation of 90%, though low, may not require immediate intervention as it is above the typical threshold for initiating supplemental oxygen. Choice B, a respiratory rate of 24 breaths per minute, falls within the normal range for an adult and may not be an immediate cause for concern. Choice D, inspiratory crackles, are indicative of fluid in the lungs but may not require immediate intervention unless accompanied by other concerning signs like decreased oxygen saturation or increased respiratory distress.
