1. A client has a fungal infection and a new prescription for amphotericin B. Which of the following laboratory values should the nurse report to the provider before initiating the medication?

Correct answer: C

Rationale: An elevated BUN level of 55 mg/dL should be reported before starting amphotericin B due to its nephrotoxic effects. Amphotericin B can cause kidney damage, and an elevated BUN indicates impaired kidney function, increasing the risk of further renal damage with this medication. Sodium, potassium, and glucose levels are not directly associated with the nephrotoxic effects of amphotericin B, making choices A, B, and D incorrect.

2. A client has a new prescription for Levothyroxine. Which of the following instructions should the nurse include?

Correct answer: C

Rationale: Levothyroxine should be taken on an empty stomach to increase absorption and efficacy. Taking it with food or antacids can interfere with its absorption, affecting the medication's effectiveness.

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

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.

4. When educating a client prescribed Rifampin, which instruction should the nurse provide?

Correct answer: A

Rationale: The correct instruction for a client prescribed Rifampin is to expect orange discoloration of urine. Rifampin is known to cause harmless discoloration of bodily fluids, including urine, which is a common side effect of this medication. It is important for the nurse to educate the client about this expected side effect to prevent unnecessary concern or discontinuation of the medication. Choices B, C, and D are incorrect because Rifampin does not require specific dietary considerations like taking it with food or increasing dairy intake. Furthermore, itching is not a common side effect that would necessitate immediate discontinuation of Rifampin.

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

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.
