LPN Pharmacology Practice Questions
1. The nurse is caring for a client diagnosed with heart failure who is taking digoxin (Lanoxin). Which sign of digoxin toxicity should the nurse monitor for?
- A. Hypertension
- B. Bradycardia
- C. Hyperglycemia
- D. Insomnia
Correct answer: B
Rationale: The correct answer is B: Bradycardia. Bradycardia is a common sign of digoxin toxicity, as digoxin can cause decreased heart rate. Therefore, monitoring the client for signs of bradycardia is crucial. Choices A, C, and D are incorrect. Hypertension is not typically associated with digoxin toxicity; instead, hypotension may occur. Hyperglycemia is not a common sign of digoxin toxicity. Insomnia is also not a typical sign of digoxin toxicity; instead, some patients may experience visual disturbances, confusion, or other neurological symptoms.
2. The client with a diagnosis of heart failure is prescribed spironolactone (Aldactone). Which laboratory value should be monitored closely by the nurse?
- A. Serum calcium
- B. Serum potassium
- C. Serum sodium
- D. Serum glucose
Correct answer: B
Rationale: The correct answer is B: Serum potassium. Spironolactone is a potassium-sparing diuretic, which can lead to hyperkalemia. Monitoring serum potassium levels is crucial to prevent adverse effects associated with high potassium levels, such as cardiac arrhythmias. Monitoring serum calcium (choice A) is not directly related to spironolactone use. Serum sodium (choice C) and serum glucose (choice D) are also not the primary laboratory values to monitor when a client is prescribed spironolactone for heart failure.
3. A client has a new prescription for clozapine. Which of the following instructions should the nurse include?
- A. You should have your white blood cell count checked regularly.
- B. You should take this medication on an empty stomach.
- C. You should avoid eating foods high in tyramine.
- D. You should avoid taking this medication with milk.
Correct answer: A
Rationale: The correct answer is A: 'You should have your white blood cell count checked regularly.' Clozapine can lead to agranulocytosis, a serious condition characterized by a low white blood cell count. Regular monitoring of the white blood cell count is crucial to detect this adverse effect early and prevent serious complications. Choices B, C, and D are incorrect because taking clozapine on an empty stomach, avoiding foods high in tyramine, or avoiding taking the medication with milk are not specific instructions related to the potential adverse effect of agranulocytosis associated with clozapine.
4. The healthcare provider is teaching a client about the use of nitroglycerin patches for angina pectoris. Which instruction should the healthcare provider include?
- A. Apply the patch to the same site each day
- B. Remove the patch at bedtime to prevent tolerance
- C. Cover the patch with a bandage to keep it in place
- D. Rotate the application site every 24 hours
Correct answer: D
Rationale: Rotating the application site every 24 hours is crucial when using nitroglycerin patches to prevent skin irritation and ensure consistent absorption of the medication. By rotating the site, the risk of local skin reactions is reduced, and the effectiveness of the nitroglycerin patch is maintained. Applying the patch to the same site each day (Choice A) can lead to skin irritation. Removing the patch at bedtime (Choice B) is not necessary as long as the prescribed wearing schedule is followed. Covering the patch with a bandage (Choice C) is not recommended as it may interfere with proper absorption.
5. A client has a new prescription for verapamil. Which of the following instructions should the nurse include?
- A. Monitor your heart rate daily.
- B. Take the medication at bedtime.
- C. Avoid consuming grapefruit juice.
- D. Take the medication with food.
Correct answer: A
Rationale: The correct answer is to instruct the client to monitor their heart rate daily when taking verapamil. Verapamil is a calcium channel blocker that can cause bradycardia, making it crucial to monitor the heart rate regularly to detect any changes promptly. Choice B, taking the medication at bedtime, is not specifically related to verapamil administration. Choice C, avoiding grapefruit juice, is more relevant to medications metabolized by CYP3A4 enzymes, not verapamil. Choice D, taking the medication with food, is not a specific instruction for verapamil, as it can be taken with or without food.
