Nursing Elites

1. When teaching a client with a prescription for Cephalexin, which of the following instructions should the nurse include?

• A. Take the medication with an antacid.
• B. Avoid dairy products while taking this medication.
• C. Expect your stools to turn black.
• D. Complete the full course of medication.

Correct answer: D

Rationale: The correct instruction for a client prescribed with Cephalexin is to complete the full course of medication. This is crucial to ensure the infection is completely treated and to reduce the risk of antibiotic resistance. Choices A, B, and C are incorrect. Taking Cephalexin with an antacid is generally not recommended as it may reduce its effectiveness. While dairy products can interfere with certain antibiotics, they do not have a direct interaction with Cephalexin. Stools turning black is not an expected side effect of Cephalexin.

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

• A. Take this medication with food.
• B. Take this medication at bedtime.
• C. Take this medication on an empty stomach.
• D. Take this medication with antacids.

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 prescription for Hydrochlorothiazide. Which of the following instructions should the nurse include?

• A. Take this medication in the morning.
• B. Increase intake of potassium-rich foods.
• C. Take this medication with food.
• D. Monitor for signs of dehydration.

Correct answer: D

Rationale: The correct answer is to monitor for signs of dehydration. Hydrochlorothiazide is a diuretic that can lead to fluid loss and electrolyte imbalance, potentially causing dehydration. Signs of dehydration include dry mouth, increased thirst, and decreased urine output. It is important for the client to be vigilant in monitoring and reporting these symptoms to healthcare providers to prevent complications. Choices A, B, and C are incorrect because taking the medication in the morning, increasing potassium-rich foods, or taking the medication with food are not specific instructions related to the potential side effects of Hydrochlorothiazide.

4. A healthcare professional is providing discharge instructions to a client who has a new prescription for Furosemide. Which of the following instructions should the healthcare professional include?

• A. Take the medication with breakfast.
• B. Increase intake of foods high in potassium.
• C. Avoid prolonged sun exposure.
• D. Limit sodium intake.

Correct answer: B

Rationale: The correct answer is B: 'Increase intake of foods high in potassium.' Furosemide, a loop diuretic, can cause potassium depletion. The healthcare professional should instruct the client to increase the intake of foods high in potassium to prevent hypokalemia, a potential side effect of Furosemide therapy. Choice A is incorrect as Furosemide is usually recommended to be taken in the morning to prevent nocturia. Choice C is unrelated to the side effects of Furosemide. Choice D, while important for overall health, is not directly related to the side effects of Furosemide.

5. When does regular insulin typically peak?

• A. 30 minutes to 2 ½ hours
• B. 1 to 3 hours
• C. 6 to 14 hours
• D. 1 to 5 hours

Correct answer: D

Rationale: Regular insulin usually peaks around 1 to 5 hours after administration. This peak time frame is important to consider when managing blood glucose levels and timing meals to coincide with insulin activity. Choice A, '30 minutes to 2 ½ hours,' is incorrect because regular insulin typically peaks later. Choice B, '1 to 3 hours,' is not the most accurate as the peak for regular insulin can extend beyond 3 hours. Choice C, '6 to 14 hours,' is incorrect as this timeframe is more indicative of long-acting insulins, not regular insulin.
