Nursing Elites

1. The nurse is reviewing the laboratory results of a client with chronic kidney disease. The client's serum calcium level is 7.5 mg/dL. Which condition should the nurse suspect?

• A. Hypercalcemia
• B. Hyperkalemia
• C. Hyponatremia
• D. Hypocalcemia

Correct answer: D

Rationale: A serum calcium level of 7.5 mg/dL is indicative of hypocalcemia, a common complication in clients with chronic kidney disease due to impaired calcium absorption and metabolism. Hypercalcemia (Choice A) is the opposite of the condition presented in the question and is characterized by elevated serum calcium levels. Hyperkalemia (Choice B) is an increased potassium level, not related to the client's serum calcium level. Hyponatremia (Choice C) is a decreased sodium level and is also not related to the client's serum calcium level.

2. A client with acute kidney injury (AKI) is experiencing hyperkalemia. What intervention should the nurse prioritize?

• A. Administer IV calcium gluconate.
• B. Administer sodium polystyrene sulfonate (Kayexalate).
• C. Administer insulin with dextrose.
• D. Restrict potassium intake in the client's diet.

Correct answer: A

Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.

3. A client with cirrhosis is admitted with jaundice, fatigue, and a distended abdomen. Which laboratory result is most important for the nurse to monitor?

• A. Ammonia level
• B. White blood cell count
• C. Albumin level
• D. Hemoglobin level

Correct answer: A

Rationale: Corrected Rationale: In clients with cirrhosis, elevated ammonia levels can lead to hepatic encephalopathy, which is a serious complication. Monitoring ammonia levels is crucial to assess for changes in mental status and initiate treatment if needed. White blood cell count (choice B) is not the most important parameter to monitor in this scenario as it does not directly relate to the complications of cirrhosis. Albumin level (choice C) and hemoglobin level (choice D) are also important in cirrhosis, but in this case, monitoring ammonia level takes precedence due to its direct association with hepatic encephalopathy.

4. A client in heart failure (HF) presents with weakness and poor urine output. Which assessment finding requires immediate action?

• A. Heart rate of 122 bpm and respiratory rate of 28.
• B. Yellow sputum expectorated.
• C. Temperature of 100.5°F (38.1°C).
• D. Shortness of breath on exertion.

Correct answer: C

Rationale: An elevated temperature may indicate infection and should be treated immediately in a client with heart failure.

5. A client with a colostomy is being discharged. What teaching is most important for the nurse to provide?

• A. Change the ostomy bag daily to prevent skin irritation.
• B. Avoid foods that can cause gas, such as broccoli.
• C. Empty the ostomy pouch when it is one-third full.
• D. Use a skin barrier to protect the surrounding skin.

Correct answer: C

Rationale: The most important teaching for a client with a colostomy is to empty the ostomy pouch when it is one-third full. This practice helps prevent leakage and skin irritation by maintaining the proper seal of the pouching system. Changing the ostomy bag daily (Choice A) is not necessary unless it leaks or becomes loose. Avoiding gas-producing foods (Choice B) is essential for some clients but is not the most important teaching. Using a skin barrier (Choice D) is important but not as crucial as emptying the ostomy pouch at the right time to prevent complications.
