1. A client is prescribed Lithium. Which of the following laboratory values should be monitored to assess for potential toxicity?

A. Serum sodium
B. Serum lithium
C. Serum potassium
D. Serum calcium

Correct answer: B

Rationale: When a client is prescribed Lithium, monitoring serum lithium levels is crucial to ensure they remain within the therapeutic range and to assess for potential toxicity. Monitoring serum lithium levels helps prevent adverse effects associated with lithium toxicity, such as nausea, vomiting, diarrhea, tremors, and confusion.

2. A client has a new prescription for Atenolol. Which of the following instructions should be included by the healthcare provider?

A. Take this medication in the morning.
B. Monitor your heart rate regularly.
C. Avoid foods high in potassium.
D. Increase your fluid intake.

Correct answer: B

Rationale: The correct answer is B. Atenolol is a beta-blocker that can cause bradycardia, leading to a decreased heart rate. Monitoring heart rate regularly is essential to detect any significant decreases promptly and seek medical attention. While choices A, C, and D may be relevant to the client's overall health, monitoring heart rate is the priority instruction due to the nature of Atenolol's effects. Taking the medication in the morning can be individualized based on the client's needs and preferences. Avoiding foods high in potassium and increasing fluid intake are generally beneficial but not directly related to managing the side effects of Atenolol.

3. A client has a prescription for Hydralazine. Which of the following instructions should the nurse include?

A. Take the medication at bedtime.
B. Monitor your blood pressure regularly.
C. Expect to have increased energy levels.
D. Avoid foods high in potassium.

Correct answer: B

Rationale: The correct answer is to monitor blood pressure regularly. Hydralazine is an antihypertensive medication that helps lower blood pressure. Monitoring blood pressure regularly is essential to ensure it remains within the target range and to assess the effectiveness of the medication. Choice A is incorrect because the timing of taking Hydralazine is usually not specified as bedtime. Choice C is incorrect because increased energy levels are not an expected effect of Hydralazine. Choice D is incorrect because Hydralazine does not interact with potassium in the same way as other medications like potassium-sparing diuretics.

4. What classification of drug is Penicillin?

A. Antiarrhythmic
B. Anticonvulsant
C. Antibacterial
D. Mood stabilizer

Correct answer: C

Rationale: Penicillin is classified as an antibacterial drug, specifically used to treat bacterial infections. It works by inhibiting the growth of bacteria, making it an effective treatment for various bacterial infections. Choices A, B, and D are incorrect as Penicillin does not belong to these drug classifications. Penicillin does not have any direct effect on heart rhythm (antiarrhythmic), does not treat seizures (anticonvulsant), and is not used to stabilize mood (mood stabilizer).

5. 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.
