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. 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.

3. A client with deep vein thrombosis (DVT) is prescribed warfarin. What lab value should the nurse review before administering the medication?

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

Correct answer: C

Rationale: The correct answer is C: International Normalized Ratio (INR). Before administering warfarin to a client with deep vein thrombosis, the nurse should review the INR to ensure the client is within the therapeutic range. INR is specifically monitored for patients on warfarin therapy to assess the clotting ability of the blood. Choices A, B, and D are incorrect as they are not the primary lab value used to monitor warfarin therapy. Prothrombin time (PT) is used to measure how long blood takes to clot. Hemoglobin and hematocrit (H&H) assess for anemia and the blood's oxygen-carrying capacity. Partial thromboplastin time (PTT) is used to monitor heparin therapy, not warfarin.

4. A male client with hypertension, who received new antihypertensive prescriptions at his last visit returns to the clinic two weeks later to evaluate his blood pressure (BP). His BP is 158/106, and he admits that he has not been taking the prescribed medication because the drugs make him feel bad. In explaining the need for hypertension control, the nurse should stress that an elevated BP places the client at risk for which pathophysiological condition?

• A. Stroke secondary to hemorrhage
• B. Myocardial infarction
• C. Heart failure
• D. Renal failure

Correct answer: A

Rationale: Stroke is a major complication of uncontrolled hypertension. Elevated BP, especially at levels like 158/106, can cause damage to blood vessels in the brain, leading to a hemorrhagic stroke. Controlling BP is essential to prevent such life-threatening events. Myocardial infarction (choice B) is more commonly associated with coronary artery disease, while heart failure (choice C) and renal failure (choice D) can be complications of uncontrolled hypertension but are not directly related to the elevated BP leading to a hemorrhagic stroke.

5. A client is receiving a blood transfusion and reports feeling chilled and short of breath. What is the nurse's priority action?

• A. Stop the transfusion and notify the healthcare provider.
• B. Administer an antihistamine as prescribed.
• C. Administer a dose of acetaminophen.
• D. Administer a PRN dose of diphenhydramine.

Correct answer: A

Rationale: The correct action for the nurse to take when a client receiving a blood transfusion reports feeling chilled and short of breath is to stop the transfusion immediately and notify the healthcare provider. These symptoms could indicate a transfusion reaction, which can be serious and even life-threatening. Stopping the transfusion is crucial to prevent further adverse reactions, and notifying the healthcare provider ensures timely intervention and appropriate management. Administering antihistamines, acetaminophen, or diphenhydramine is not the priority in this situation and may delay necessary actions to address the potential transfusion reaction.
