Nursing Elites

1. The LPN/LVN is assisting with the care of a client who has been diagnosed with a myocardial infarction (MI). Which laboratory test result would the nurse expect to see elevated within the first 24 hours of the client's admission?

• A. Serum troponin
• B. Serum creatinine
• C. Serum sodium
• D. Serum albumin

Correct answer: A

Rationale: Elevated serum troponin levels are indicative of myocardial damage and are commonly used as a diagnostic marker for myocardial infarction. Troponin levels typically rise within a few hours of an MI and remain elevated for several days, making it a crucial test for early detection and monitoring of cardiac injury. Serum creatinine is not typically elevated in the acute phase of a myocardial infarction. Serum sodium and serum albumin levels are not directly associated with myocardial infarction and are unlikely to be elevated in the first 24 hours following an MI.

2. The healthcare professional is assisting in the care of a client diagnosed with heart failure. The client is receiving furosemide (Lasix). Which laboratory value should the healthcare professional monitor most closely?

• A. Serum calcium
• B. Serum potassium
• C. Serum sodium
• D. Serum glucose

Correct answer: B

Rationale: Furosemide is a loop diuretic that can lead to significant potassium loss, making it crucial to monitor the client's serum potassium levels. Hypokalemia (low potassium levels) can result from furosemide use, potentially leading to adverse effects such as cardiac dysrhythmias. Therefore, close monitoring of serum potassium levels is essential to prevent complications in clients receiving furosemide. Monitoring serum calcium, sodium, or glucose levels is not the priority when administering furosemide.

3. A client with a diagnosis of angina pectoris is prescribed nitroglycerin. The nurse should teach the client to take the medication in which way?

• A. Take one tablet daily with breakfast
• B. Take one tablet every 5 minutes as needed, up to three times
• C. Take one tablet every hour until pain subsides
• D. Take one tablet only if pain does not subside after 30 minutes

Correct answer: B

Rationale: Nitroglycerin is a rapid-acting medication used to relieve angina pain by dilating blood vessels. The correct administration is to take one tablet every 5 minutes as needed, up to three doses. This dosing regimen helps in managing acute angina episodes effectively. Choice A is incorrect because nitroglycerin is not taken once daily. Choice C is incorrect because waiting for an hour between doses may not provide timely relief during angina attacks. Choice D is incorrect as it suggests waiting for 30 minutes before taking another dose, which could delay symptom relief in acute situations.

4. The healthcare provider is monitoring a client with left-sided heart failure. Which assessment finding indicates that the client's condition is worsening?

• A. Clear lung sounds
• B. Increased peripheral pulses
• C. Bibasilar crackles
• D. Improved activity tolerance

Correct answer: C

Rationale: Bibasilar crackles are abnormal lung sounds that indicate fluid accumulation in the lungs, a sign that left-sided heart failure is worsening. This finding suggests that the client's condition is deteriorating and requires prompt intervention to prevent further complications. Clear lung sounds (Choice A) are normal and would not indicate worsening heart failure. Increased peripheral pulses (Choice B) may be seen in conditions like anxiety or exercise, but not specifically in worsening left-sided heart failure. Improved activity tolerance (Choice D) would be a positive sign, not an indicator of worsening heart failure.

5. The client with heart failure is receiving digoxin (Lanoxin). The nurse should monitor the client for which sign of digoxin toxicity?

• A. Hypertension
• B. Bradycardia
• C. Hyperglycemia
• D. Insomnia

Correct answer: B

Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin can cause disturbances in the heart's electrical conduction system, leading to a slower heart rate. Therefore, the nurse should closely monitor the client's heart rate for signs of bradycardia, which could indicate digoxin toxicity. Hypertension (Choice A), hyperglycemia (Choice C), and insomnia (Choice D) are not typically associated with digoxin toxicity. Therefore, they are incorrect choices for this question.
