1. A healthcare professional is preparing to administer morphine 4 mg IV to a client. Available is morphine 10 mg/mL. How many mL should the healthcare professional administer?

• A. 0.2 mL
• B. 0.4 mL
• C. 0.6 mL
• D. 0.8 mL

Correct answer: B

Rationale: To administer 4 mg from a solution of 10 mg/mL, the healthcare professional should administer 0.4 mL. The calculation is done by dividing the desired dose (4 mg) by the concentration of the solution (10 mg/mL), which equals 0.4 mL. Choice A (0.2 mL) is incorrect because it is half of the correct calculation. Choice C (0.6 mL) is incorrect because it is 50% more than the correct calculation. Choice D (0.8 mL) is incorrect because it exceeds the correct calculation.

2. What is the correct definition of drug absorption?

• A. Movement of a drug from the site of administration to various tissues of the body
• B. Describes the absorption, distribution, metabolism, and excretion of drugs
• C. These types of drugs can be taken over the counter
• D. This addresses how various drugs affect different forms of the body

Correct answer: A

Rationale: The correct definition of drug absorption is the movement of a drug from the site of administration into various tissues of the body. It is the process by which a drug is taken up and enters the systemic circulation. Choice B describes the pharmacokinetics of drugs, including absorption, distribution, metabolism, and excretion, but it is not a specific definition of drug absorption. Choice C is unrelated to drug absorption, as it refers to over-the-counter drugs. Choice D is too vague and does not specifically address the process of drug absorption.

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

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

Correct answer: A

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, leading to reduced effectiveness of the medication.

4. A client has a new prescription for Digoxin. Which of the following instructions should the nurse provide?

• A. Monitor your heart rate before taking the medication.
• B. Increase your intake of high-potassium foods.
• C. Take the medication with a full glass of milk.
• D. Expect your stools to be black and tarry.

Correct answer: A

Rationale: Clients prescribed Digoxin should monitor their heart rate before each dose. This is essential to identify any potential bradycardia, defined as a heart rate below 60 bpm, which can be a side effect of Digoxin. Any significant changes in heart rate should be reported promptly to the healthcare provider for further evaluation and management. Choice B is incorrect because increasing intake of high-potassium foods can lead to hyperkalemia, a condition that can be exacerbated by Digoxin. Choice C is incorrect as taking Digoxin with a full glass of milk is not necessary. Choice D is incorrect as black, tarry stools are not an expected side effect of Digoxin.

5. A client is receiving Morphine IV for pain management. Which of the following actions should the nurse take to monitor for adverse effects?

• A. Monitor the client's respiratory rate every 15 minutes.
• B. Monitor the client's blood pressure every 30 minutes.
• C. Monitor the client's oxygen saturation every hour.
• D. Monitor the client's heart rate every 5 minutes.

Correct answer: A

Rationale: The correct action for the nurse to monitor for adverse effects of Morphine IV is to check the client's respiratory rate every 15 minutes. Respiratory depression is a potentially life-threatening adverse effect of Morphine. Monitoring the respiratory rate frequently allows for early detection and intervention if needed. Monitoring blood pressure, oxygen saturation, or heart rate alone may not provide early signs of respiratory depression, which is a critical adverse effect of Morphine IV.
