Nursing Elites

1. A client has an infection and a prescription for gentamicin intermittent IV bolus every 8 hr. A peak and trough is required with the next dose. Which of the following actions should be taken to obtain an accurate gentamicin serum level?

• A. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
• B. Draw a peak level 90 min prior to administering the medication and a trough level 90 min after the dose.
• C. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
• D. Draw a peak level at 0900 and a trough level at 2100.

Correct answer: C

Rationale: To obtain an accurate gentamicin serum level, the trough should be drawn immediately before administering the medication, and the peak level should be drawn 30 minutes after the dose. This timing allows for the assessment of the lowest and highest drug concentrations in the bloodstream, ensuring therapeutic levels are achieved while minimizing the risk of toxicity. Choice A is correct as it follows this timing protocol. Choices B and D have incorrect timing for peak and trough levels, which would not provide an accurate representation of the drug's concentration in the bloodstream.

2. A client with angina asks about obtaining a prescription for sildenafil to treat erectile dysfunction. Which of the following medications is contraindicated with Sildenafil?

• A. Aspirin
• B. Isosorbide
• C. Clopidogrel
• D. Atorvastatin

Correct answer: B

Rationale: Isosorbide is an organic nitrate used to manage angina. Concurrent use of sildenafil with organic nitrates, like isosorbide, is contraindicated due to the risk of fatal hypotension. It is essential for clients to avoid taking nitrate medications within 24 hours of using isosorbide to prevent serious complications.

3. A client has a new prescription for Lovastatin. Which of the following instructions should the nurse include?

• A. Take this medication on an empty stomach.
• B. Take this medication in the morning.
• C. Take this medication at bedtime.
• D. Increase your intake of potassium-rich foods.

Correct answer: C

Rationale: The correct instruction for taking Lovastatin is to take it at bedtime. Cholesterol production in the liver is highest at night, so taking Lovastatin at bedtime aligns with the body's natural rhythm and maximizes its effectiveness.

4. A client with tobacco use disorder is being educated about Nicotine replacement therapy. Which statement by the client indicates an understanding of the teaching?

• A. I should avoid eating right before chewing a piece of nicotine gum.
• B. I will need to stop using the nicotine gum after 1 year.
• C. I know that nicotine gum is a safe alternative to smoking during pregnancy.
• D. I must chew the nicotine gum quickly for about 15 minutes.

Correct answer: A

Rationale: The correct answer is A. To maximize the effectiveness of nicotine gum, the client should avoid eating or drinking 15 minutes before and while using it. This helps ensure proper absorption of nicotine through the oral mucosa. Choice B is incorrect because the duration of nicotine gum use can vary depending on the individual's needs and progress. Choice C is incorrect as nicotine gum should be used during pregnancy only under healthcare provider guidance. Choice D is incorrect because nicotine gum should be chewed slowly until a tingling sensation is felt, then parked between the cheek and gum until the tingling stops.

5. A healthcare professional is caring for a client who is prescribed Digoxin. Which of the following findings should the healthcare professional monitor to assess for potential toxicity?

• A. Bradycardia
• B. Hypertension
• C. Hypoglycemia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is A: Bradycardia. Bradycardia is a common sign of Digoxin toxicity. Digoxin can cause bradycardia due to its effects on the heart's electrical conduction system. Monitoring the client's heart rate regularly is essential to detect and manage toxicity promptly. Choice B, Hypertension, is incorrect as Digoxin toxicity typically presents with bradycardia and not hypertension. Choices C and D, Hypoglycemia and Hypercalcemia, are also incorrect as they are not typically associated with Digoxin toxicity.
