1. 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.
2. A client has a new prescription for Cyclobenzaprine to treat muscle spasms. Which of the following instructions should the nurse include in the teaching?
- A. Avoid driving or operating heavy machinery while taking this medication.
- B. Take this medication on an empty stomach for best results.
- C. Take this medication only when experiencing muscle pain.
- D. Increase your intake of potassium-rich foods while taking this medication.
Correct answer: A
Rationale: The correct instruction that the nurse should include in the teaching for a client prescribed Cyclobenzaprine is to avoid driving or operating heavy machinery while taking this medication. Cyclobenzaprine can cause drowsiness, so it is important to advise clients to avoid activities that require alertness and coordination to prevent accidents or injuries. Choice B is incorrect because Cyclobenzaprine can be taken with or without food. Choice C is incorrect because Cyclobenzaprine is typically taken regularly as prescribed, not just when experiencing muscle pain. Choice D is incorrect because there is no specific need to increase potassium-rich foods while taking Cyclobenzaprine.
3. A client has a new prescription for a Nitroglycerin transdermal patch for Angina Pectoris. Which of the following instructions should the nurse include?
- A. Remove the patch each evening.
- B. Do not cut the patch in half even if angina attacks are under control.
- C. Take off the nitroglycerin patch if a headache occurs.
- D. Apply a new patch every 48 hours.
Correct answer: A
Rationale: The correct instruction is to remove the nitroglycerin patch each evening to prevent tolerance. This allows for a 10- to 12-hour nitrate-free period daily, reducing the risk of developing tolerance to nitroglycerin. Cutting the patch in half is not recommended because it can alter the dosing and absorption rate, leading to inadequate symptom control. Taking off the patch for a headache is not necessary as headaches are a common side effect that may improve with continued use. Applying a new patch every 48 hours is not correct as it may not provide continuous symptom relief for angina.
4. A client has a new prescription for Phenytoin. Which of the following instructions should the nurse include?
- A. Brush and floss your teeth regularly.
- B. Avoid drinking grapefruit juice.
- C. Take this medication with food.
- D. Increase your intake of calcium-rich foods.
Correct answer: A
Rationale: The correct answer is to instruct the client to brush and floss their teeth regularly. Phenytoin can lead to gingival hyperplasia, making oral hygiene crucial to prevent complications. Encouraging good oral care practices helps reduce the risk of adverse effects on the gums and teeth. Avoiding grapefruit juice is not specifically related to Phenytoin. While some medications require intake with food, Phenytoin is usually taken on an empty stomach for better absorption. Increasing calcium-rich foods is not directly associated with Phenytoin therapy.
5. Which of the following medications is a bronchodilator?
- A. Albuterol
- B. Omeprazole
- C. Ondansetron
- D. Senna
Correct answer: A
Rationale: Albuterol is classified as a bronchodilator, which is commonly used to treat conditions like asthma by relaxing the muscles in the airways and increasing airflow to the lungs. Omeprazole is a proton pump inhibitor used to reduce stomach acid production, while ondansetron is an anti-nausea medication, and senna is a laxative.
