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. A client is experiencing shortness of breath and wheezing. What is the nurse's first action?

• A. Administer bronchodilator medication
• B. Check the client's oxygen saturation
• C. Encourage the client to use pursed-lip breathing
• D. Elevate the head of the bed

Correct answer: A

Rationale: Administering a bronchodilator is the priority intervention to open the airways and relieve wheezing and shortness of breath. Bronchodilators work quickly to dilate the airways, making it easier for the client to breathe. Checking oxygen saturation is important but can be done after initiating bronchodilator therapy. Encouraging pursed-lip breathing and elevating the head of the bed can help improve breathing patterns but should follow the administration of the bronchodilator.

3. A client reports unilateral leg swelling after a long flight. What complication is the nurse most concerned about?

• A. Monitor for signs of a pulmonary embolism.
• B. Assess for signs of dehydration.
• C. Monitor for signs of compartment syndrome.
• D. Check the client’s oxygen saturation levels.

Correct answer: A

Rationale: The correct answer is A. Unilateral leg swelling following a long flight may indicate a pulmonary embolism, which is a life-threatening complication requiring immediate attention. Pulmonary embolism occurs when a blood clot travels to the lungs, potentially blocking blood flow and leading to serious complications. Choices B, C, and D are incorrect because dehydration, compartment syndrome, and oxygen saturation levels are not typically associated with unilateral leg swelling after a long flight. While dehydration can cause leg cramps, compartment syndrome is more commonly associated with trauma or injury, and oxygen saturation levels are not the primary concern in this scenario.

4. A male client with heart failure becomes short of breath, anxious, and has pink frothy sputum. What is the first action the nurse should take?

• A. Consult the charge nurse about administering morphine.
• B. Administer the morphine sulfate as prescribed.
• C. Withhold the morphine until the dyspnea resolves.
• D. Review the need for the morphine prescription with the provider.

Correct answer: B

Rationale: The correct answer is B: Administer the morphine sulfate as prescribed. In this situation, the client is experiencing symptoms of acute pulmonary edema, a complication of heart failure. Morphine is indicated as it helps reduce anxiety and respiratory distress by decreasing preload and afterload. It dilates blood vessels, reducing the workload of the heart and improving oxygenation. The priority is to administer the morphine promptly to alleviate the client's distress and improve oxygenation. Consulting the charge nurse (A) or reviewing the need for the morphine prescription with the provider (D) would cause a delay in providing essential treatment. Withholding the morphine (C) would not be appropriate as it is indicated for this condition.

5. A nurse is caring for a client with a chest tube following lung surgery. What is the most important intervention to ensure the chest tube functions properly?

• A. Clamp the tube if there is excessive drainage
• B. Empty the drainage chamber every 2 hours
• C. Keep the drainage system below chest level
• D. Milk the tube to prevent clots from forming

Correct answer: C

Rationale: The correct answer is C. Keeping the chest tube drainage system below chest level ensures that gravity assists with drainage and prevents fluid or air from flowing back into the pleural space, which could compromise lung function. Clamping the tube if there is excessive drainage (choice A) is incorrect as it can lead to a buildup of pressure and compromise the drainage system. Emptying the drainage chamber every 2 hours (choice B) is important but not as crucial as maintaining the drainage system below chest level. Milking the tube to prevent clots from forming (choice D) is incorrect and could lead to complications such as tube occlusion or damage to the tissue.
