1. A client has a new prescription for metronidazole. The client should avoid which of the following?

A. Dairy products
B. Alcohol
C. Leafy green vegetables
D. Grapefruit juice

Correct answer: B

Rationale: The correct answer is B: Alcohol. Clients should avoid alcohol while taking metronidazole to prevent a disulfiram-like reaction, which can cause symptoms such as nausea, vomiting, headache, and flushing. Alcohol can interact with metronidazole and lead to adverse effects. Choices A, C, and D are not typically contraindicated with metronidazole. Dairy products, leafy green vegetables, and grapefruit juice do not have significant interactions with metronidazole, unlike alcohol.

2. Which medication is a beta blocker?

A. Atenolol (Tenormin)
B. Verapamil (Calan)
C. Captopril (Capoten)
D. Clopidogrel (Plavix)

Correct answer: A

Rationale: Atenolol (Tenormin) is a beta blocker commonly used to treat conditions like hypertension and angina by blocking the action of adrenaline on the heart. Verapamil is a calcium channel blocker, Captopril is an ACE inhibitor, and Clopidogrel is an antiplatelet medication. Therefore, the correct answer is Atenolol (Tenormin) as it belongs to the beta blocker class of medications.

3. When teaching a client about preventing Otitis Externa, which of the following instructions should the nurse include?

A. Clean the ear with a cotton-tipped swab daily.
B. Place earplugs in the ears when sleeping at night.
C. Use a cool water irrigation solution to remove earwax.
D. Tip the head to the side to remove water from the ears after showering.

Correct answer: D

Rationale: To prevent Otitis Externa, the nurse should instruct the client to tip the head to the side to allow water to drain out after showering or swimming. This helps to prevent moisture buildup in the ear canal, reducing the risk of developing Otitis Externa, commonly known as swimmer's ear.

4. A client with HIV is beginning therapy with zidovudine. The nurse should monitor the client for which of the following adverse effects of this medication?

A. Fatigue
B. Blurred vision
C. Ringing in the ears
D. Constipation

Correct answer: A

Rationale: Fatigue is a common adverse effect of zidovudine due to its impact on bone marrow, leading to anemia. Zidovudine is known to suppress bone marrow function, resulting in decreased production of red blood cells and subsequently causing fatigue due to anemia. Monitoring for fatigue is essential to ensure early detection and management of this adverse effect.

5. What is the classification for the drug valproate?

A. Anti-diabetic
B. Anti-convulsant
C. Anti-ulcer agent
D. Anti-hypertensive

Correct answer: B

Rationale: Valproate is classified as an anticonvulsant. It is commonly used to treat epilepsy and bipolar disorder by stabilizing electrical activity in the brain. Therefore, the correct classification for valproate is as an anticonvulsant. Options A, C, and D are incorrect because valproate is not used to treat diabetes, ulcers, or hypertension.
