LPN Pharmacology Practice Test
1. A client has a new prescription for levothyroxine. Which of the following instructions should the nurse include?
- A. Take the medication on an empty stomach.
- B. Take the medication with food.
- C. Take the medication at bedtime.
- D. Take the medication with an antacid.
Correct answer: A
Rationale: The correct answer is A: 'Take the medication on an empty stomach.' Levothyroxine should be taken on an empty stomach to ensure optimal absorption. Food, especially high-fiber foods, can interfere with the absorption of levothyroxine. Taking it with an antacid or at bedtime may also affect its absorption. Instructing the client to take the medication on an empty stomach will help maintain consistent blood levels of levothyroxine. Choice B is incorrect as taking levothyroxine with food can reduce its absorption. Choice C is incorrect because taking levothyroxine at bedtime may lead to inconsistent blood levels due to food intake during the day. Choice D is incorrect as antacids can interfere with the absorption of levothyroxine.
2. The healthcare provider is reinforcing teaching for a client who is starting statin therapy. Which dietary advice should the healthcare provider give?
- A. Eat more whole grains.
- B. Avoid foods high in potassium.
- C. Avoid grapefruit and grapefruit juice.
- D. Increase intake of dairy products.
Correct answer: C
Rationale: The correct answer is C: Avoid grapefruit and grapefruit juice. Grapefruit and grapefruit juice can interfere with the metabolism of statins, leading to an increased risk of adverse effects. It is crucial for clients on statin therapy to avoid grapefruit products to ensure the medication's effectiveness and safety. Choices A, B, and D are incorrect because they do not directly impact the metabolism or effectiveness of statin therapy.
3. A client diagnosed with angina pectoris returns to the nursing unit after experiencing an angioplasty. The nurse reinforces instructions to the client regarding the procedure and home care measures. Which statement by the client indicates an understanding of the instructions?
- A. I am considering cutting my workload.
- B. I need to cut down on cigarette smoking.
- C. I am so relieved that my heart is repaired.
- D. I need to adhere to my dietary restrictions.
Correct answer: B
Rationale: The correct answer is B because cutting down on cigarette smoking is crucial for improving heart health after angioplasty. Smoking cessation helps in reducing the risk of complications and promotes better outcomes. Choices A and C are not directly related to post-angioplasty care. While reducing workload may be beneficial, it is not specifically related to the client's cardiac health. Feeling relieved that the heart is repaired is a positive emotional response but does not reflect understanding of the necessary measures. Adhering to dietary restrictions is important, but in this scenario, smoking cessation takes higher priority due to its immediate impact on heart health.
4. A healthcare provider is providing discharge instructions to a client who has a new prescription for digoxin. Which of the following instructions should the healthcare provider include?
- A. Take the medication at bedtime.
- B. Avoid taking antacids with this medication.
- C. Monitor your pulse rate daily.
- D. Increase your intake of potassium-rich foods.
Correct answer: C
Rationale: The correct answer is C: 'Monitor your pulse rate daily.' Monitoring the pulse rate daily is crucial when taking digoxin as it helps in early detection of digoxin toxicity. Digoxin can cause toxicity, which may manifest as changes in the heart rate, making monitoring the pulse rate an essential part of managing the medication. It is important for the client to be aware of their normal pulse rate and report any significant changes to their healthcare provider promptly. Choices A, B, and D are incorrect. Taking digoxin at bedtime is not a specific instruction related to monitoring its effects. Avoiding antacids is relevant for some medications, but not a key concern with digoxin. Increasing potassium-rich foods may interact with digoxin due to its effect on potassium levels, but monitoring the pulse rate is a more direct and immediate need for safety.
5. A client with heart failure is prescribed furosemide (Lasix). The nurse should monitor the client for which potential electrolyte imbalance?
- A. Hyperkalemia
- B. Hypernatremia
- C. Hypokalemia
- D. Hypocalcemia
Correct answer: C
Rationale: When a client with heart failure is prescribed furosemide, the nurse should monitor for hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss, which increases the risk of hypokalemia. Hypokalemia can have serious implications such as cardiac dysrhythmias. Therefore, it is essential to closely monitor the client's serum potassium levels while on furosemide to prevent complications. Hyperkalemia (Choice A) is incorrect because furosemide leads to potassium loss, not retention. Hypernatremia (Choice B) is not typically associated with furosemide use. Hypocalcemia (Choice D) is not a common electrolyte imbalance caused by furosemide.
