Nursing Elites

1. A client with liver cirrhosis is receiving lactulose for hepatic encephalopathy. Which finding indicates the medication is effective?

• A. The client's level of consciousness improves.
• B. The client's ammonia level decreases.
• C. The client has three bowel movements daily.
• D. The client's liver enzymes return to normal.

Correct answer: B

Rationale: The correct answer is B: "The client's ammonia level decreases." In hepatic encephalopathy, elevated ammonia levels contribute to neurological symptoms. Lactulose works by promoting the excretion of ammonia in the stool, leading to decreased serum ammonia levels. Therefore, a decrease in ammonia levels indicates that lactulose is effectively reducing ammonia buildup, improving hepatic encephalopathy symptoms. Choices A, C, and D are incorrect because improvement in level of consciousness, bowel movements, or normalization of liver enzymes may not directly reflect the effectiveness of lactulose in reducing ammonia levels and improving hepatic encephalopathy.

2. 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.

3. Before administering digoxin to a client with heart failure, what is the most important assessment for the nurse to perform?

• A. Check the client's blood pressure
• B. Monitor the client's heart rate
• C. Assess the client's respiratory rate
• D. Review the client's potassium level

Correct answer: B

Rationale: The correct answer is to monitor the client's heart rate. Digoxin slows the heart rate, so it is crucial to assess the heart rate before administering the medication. If the heart rate is below 60 beats per minute, the dose should be held, and the healthcare provider should be notified. Checking the blood pressure (Choice A) is important but not as crucial as monitoring the heart rate in this case. Assessing the respiratory rate (Choice C) is not directly related to the action of digoxin. Reviewing the client's potassium level (Choice D) is important for clients taking digoxin due to the risk of hypokalemia, but assessing the heart rate takes priority.

4. The nurse identifies an electrolyte imbalance, a weight gain of 4.4 lbs in 24 hours, and an elevated central venous pressure for a client with full-thickness burns. Which intervention should the nurse implement?

• A. Administer diuretics
• B. Review urine output
• C. Auscultate for irregular heart rate
• D. Increase oral fluid intake

Correct answer: C

Rationale: An elevated CVP and sudden weight gain indicate fluid overload, which can strain the heart. Auscultating for an irregular heart rate is crucial as electrolyte imbalances and fluid shifts after burns can lead to cardiac complications. Monitoring the heart rate is a priority to detect any cardiac distress early. While reviewing urine output and administering diuretics are important interventions, they should come after ensuring the client's cardiac status is stable. Increasing oral fluid intake may exacerbate the fluid overload, making it an inappropriate intervention in this scenario.

5. A client's chest tube insertion site has crepitus (crackling sensation) upon palpation. What is the nurse's next step?

• A. Apply a pressure dressing to the chest tube site.
• B. Administer an oral antihistamine.
• C. Assess the client for allergies to cleaning agents.
• D. Measure the area of swelling and crackling.

Correct answer: D

Rationale: The correct next step for the nurse is to measure the area of crepitus. Crepitus indicates subcutaneous emphysema, which is a serious condition requiring monitoring. Applying a pressure dressing (Choice A) could worsen the condition by trapping air under the skin. Administering an oral antihistamine (Choice B) is not indicated for crepitus. Assessing for allergies to cleaning agents (Choice C) is not the priority when dealing with crepitus and subcutaneous emphysema.
