Nursing Elites

1. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?

• A. To reduce abdominal pressure on the diaphragm
• B. To promote oxygenation by improving lung expansion
• C. To encourage use of accessory muscles for breathing
• D. To drain secretions and prevent aspiration

Correct answer: D

Rationale: Elevating the head of the bed in a client with acute respiratory distress syndrome (ARDS) is essential to drain secretions and prevent aspiration. This position helps facilitate the removal of secretions from the airways, reducing the risk of aspiration pneumonia. Choices A, B, and C are incorrect as the primary reason for elevating the head of the bed in ARDS is to assist with secretion drainage and prevent complications associated with aspiration.

2. A client with a ruptured spleen underwent an emergency splenectomy. Twelve hours later, the client’s urine output is 25 ml/hour. What is the most likely cause?

• A. This is a normal finding after surgery.
• B. Oliguria signals tubular necrosis related to hypoperfusion.
• C. Oliguria signals dehydration and fluid loss.
• D. Urine output of 25 ml/hour is an expected finding after splenectomy.

Correct answer: B

Rationale: Oliguria, or decreased urine output, after surgery can indicate tubular necrosis due to hypoperfusion, which may require intervention to restore renal function. Choice A is incorrect as oliguria is not a normal finding after surgery. Choice C is incorrect because dehydration is less likely in this context compared to tubular necrosis. Choice D is incorrect as a urine output of 25 ml/hour is not expected after splenectomy and should raise concern for renal impairment.

3. A client with deep vein thrombosis (DVT) is prescribed heparin. What lab value should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT).
• B. Partial thromboplastin time (PTT).
• C. International Normalized Ratio (INR).
• D. Hemoglobin and hematocrit.

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.

4. The nurse is caring for a client with a history of congestive heart failure (CHF) who is receiving digoxin therapy. The client reports seeing halos around lights. Which action should the nurse take?

• A. Assess the client's digoxin level
• B. Increase the client's fluid intake
• C. Check the client's blood pressure
• D. Administer a dose of potassium

Correct answer: A

Rationale: Seeing halos around lights is a classic symptom of digoxin toxicity. The nurse should assess the client's digoxin level to determine if the dose needs to be adjusted or if the medication should be held. Increasing fluid intake or checking blood pressure would not directly address the symptom of halos around lights. Administering a dose of potassium is not indicated without knowing the digoxin level and could potentially worsen the toxicity.

5. A client with cirrhosis is receiving lactulose. What is the most important assessment for the nurse to monitor?

• A. Monitor the client's ammonia levels.
• B. Monitor the client's blood glucose level.
• C. Monitor the client's potassium levels.
• D. Monitor the client's level of consciousness.

Correct answer: D

Rationale: The correct answer is to monitor the client's level of consciousness. Lactulose is used to reduce ammonia levels in hepatic encephalopathy. Monitoring the level of consciousness helps assess the effectiveness of lactulose therapy in improving the client's condition. Monitoring ammonia levels (choice A) is important, but assessing the client's response to therapy through their level of consciousness is more crucial. Blood glucose levels (choice B) and potassium levels (choice C) are not directly related to lactulose therapy for cirrhosis and hepatic encephalopathy.
