Nursing Elites

1. A client has a new prescription for Labetalol. Which of the following instructions should be provided?

• A. Take the medication with food.
• B. Monitor your blood glucose levels.
• C. Expect a rapid heart rate.
• D. Increase your intake of high-sodium foods.

Correct answer: A

Rationale: The correct answer is A: Take the medication with food. Labetalol should be taken with food to increase absorption and reduce the risk of orthostatic hypotension. Taking it with food helps in better absorption and minimizes the potential drop in blood pressure when standing up, which can occur with this medication. Choice B is incorrect as Labetalol is not primarily associated with affecting blood glucose levels. Choice C is incorrect as Labetalol is a beta-blocker that would actually lower heart rate, not increase it. Choice D is incorrect because increasing intake of high-sodium foods could counteract the antihypertensive effects of Labetalol.

2. A healthcare professional is preparing to administer furosemide 80 mg PO daily. The available furosemide oral solution is 10 mg/1 mL. How many mL should the healthcare professional administer?

• A. 8 mL
• B. 10 mL
• C. 6 mL
• D. 12 mL

Correct answer: A

Rationale: To determine the volume to administer, divide the desired dose by the available concentration. In this case, 80 mg divided by 10 mg/mL equals 8 mL. Therefore, the healthcare professional should administer 8 mL of furosemide oral solution. Choice B, 10 mL, is incorrect as it does not reflect the accurate calculation. Choices C and D, 6 mL and 12 mL respectively, are also incorrect as they do not match the correct calculation based on the provided concentration and dose.

3. Which of the following is a potassium-sparing diuretic?

• A. Furosemide
• B. Spironolactone
• C. Hydrochlorothiazide
• D. Bumetanide

Correct answer: B

Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by antagonizing the aldosterone receptor, leading to potassium retention and sodium excretion. This mechanism makes it a suitable choice for conditions where potassium retention is desired, such as in patients with heart failure or liver cirrhosis. Choices A, C, and D are not potassium-sparing diuretics. Furosemide, hydrochlorothiazide, and bumetanide are loop diuretics and thiazide diuretics, respectively, which promote the excretion of potassium.

4. What is pharmacodynamics?

• A. The medical reference summarizing standards of drug purity, strength, and directions for synthesis
• B. The drug's actions at receptor sites and the physiological, chemical, and behavioral effects produced by these actions
• C. The maximum response that a drug can produce
• D. Movements of the drugs throughout the body

Correct answer: B

Rationale: Pharmacodynamics refers to the drug's actions at receptor sites and the physiological, chemical, and behavioral effects produced by these actions. It involves understanding how drugs interact with the body at the molecular level to produce their effects, including mechanisms of action, receptor binding, and downstream physiological responses. Choice A is incorrect because it describes pharmacopeia, which is a reference book containing standards for drugs. Choice C refers to efficacy, which is the maximum effect a drug can produce. Choice D describes pharmacokinetics, which focuses on the movement of drugs within the body.

5. A client has a new prescription for Hydrochlorothiazide. Which of the following information should the nurse include?

• A. Take the medication with food.
• B. Plan to take the medication at bedtime.
• C. Expect increased swelling of the ankles.
• D. Fluid intake should be limited in the morning.

Correct answer: A

Rationale: The correct answer is to take the medication with food. Hydrochlorothiazide should be taken with or after meals to prevent gastrointestinal upset. Taking it with food can help reduce the chances of stomach discomfort or nausea. It is not necessary to take the medication at bedtime, expect increased swelling of the ankles, or limit fluid intake in the morning when taking Hydrochlorothiazide. Therefore, choices B, C, and D are incorrect.
