1. A client is prescribed diazepam for muscle spasms. What instruction should the nurse include in the client's teaching plan?
- A. Avoid drinking alcohol
- B. Take with food to avoid gastrointestinal upset
- C. Increase fluid intake
- D. Take medication with grapefruit juice
Correct answer: A
Rationale: The correct instruction for a client prescribed diazepam for muscle spasms is to avoid drinking alcohol. Diazepam can cause drowsiness and enhance the effects of alcohol, leading to increased sedation and impaired cognitive function. Clients should be advised to avoid alcohol consumption while taking diazepam to prevent these adverse effects and ensure their safety.
2. A client with a diagnosis of bipolar disorder is prescribed topiramate. The nurse should monitor for which potential adverse effect?
- A. Cognitive impairment
- B. Weight gain
- C. Liver toxicity
- D. Weight loss
Correct answer: A
Rationale: Correct. Topiramate is associated with cognitive impairment as an adverse effect. It is important for the nurse to monitor the client's cognitive function while on this medication to assess for any signs of cognitive decline or impairment. Choice B, weight gain, is incorrect as topiramate is actually associated with weight loss rather than weight gain. Choice C, liver toxicity, is also incorrect as topiramate is not known to cause liver toxicity. Choice D, weight loss, is not the correct answer as topiramate is not associated with weight gain.
3. A client with hypertension is prescribed atenolol. The nurse should monitor for which potential side effect?
- A. Bradycardia
- B. Tachycardia
- C. Dry mouth
- D. Hypotension
Correct answer: A
Rationale: When a client is prescribed atenolol, a beta-blocker, the nurse should monitor for bradycardia, which is a potential side effect. Atenolol works by slowing the heart rate, so monitoring the client's heart rate is essential to detect and manage bradycardia promptly.
4. A client is prescribed cyclobenzaprine for muscle spasms. The nurse should instruct the client to avoid which substance while taking this medication?
- A. Alcohol
- B. Caffeine
- C. Nicotine
- D. Dairy products
Correct answer: A
Rationale: The correct answer is A: Alcohol. When taking cyclobenzaprine, it is important to avoid alcohol as it can potentiate the central nervous system depressant effects of the medication. This interaction can lead to increased drowsiness, dizziness, and impaired coordination. Therefore, it is essential for the client to refrain from alcohol consumption while on cyclobenzaprine to prevent these adverse effects and ensure their safety. Choices B, C, and D are incorrect because caffeine, nicotine, and dairy products do not have significant interactions with cyclobenzaprine. While caffeine and nicotine may have stimulant effects that could theoretically counteract some of the sedative effects of cyclobenzaprine, they are not contraindicated. Dairy products, on the other hand, do not interact with cyclobenzaprine and can be consumed safely.
5. A client with a history of atrial fibrillation is prescribed verapamil. The nurse should monitor for which potential side effect?
- A. Constipation
- B. Diarrhea
- C. Headache
- D. Hypotension
Correct answer: A
Rationale: Verapamil, a calcium channel blocker, can commonly cause constipation due to its effects on smooth muscle relaxation in the gastrointestinal tract. Therefore, monitoring for constipation is important when a client is prescribed verapamil.
