1. What does it mean when a medication has a half-life?

Correct answer: B

Rationale: When a medication has a half-life, it refers to the time it takes for half of the dose to be eliminated from the bloodstream. This parameter is crucial in understanding the duration of action and dosing intervals for medications in clinical practice. Choice A is incorrect as the half-life is not about how long the medication lasts but about elimination from the body. Choice C is incorrect because the half-life is not about the peak effectiveness of the medicine. Choice D is incorrect as it does not accurately define the concept of half-life.

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

Correct answer: D

Rationale: The correct instruction is to administer Enoxaparin in the abdomen as a subcutaneous injection. This method helps prevent bleeding complications associated with the medication. Massaging the injection site after administration should be avoided to reduce the risk of local irritation or bleeding. While rotating injection sites between the arms and thighs is a good practice for some medications, it is not recommended for Enoxaparin. Consistent administration in the abdomen ensures optimal absorption and helps avoid complications.

3. A female client with tobacco use disorder is being educated by a nurse about Nicotine replacement therapy. Which of the following statements by the client shows understanding of the teaching?

Correct answer: A

Rationale: The correct answer is A. The client should avoid eating or drinking 15 minutes prior to and while chewing the nicotine gum. Choice B is incorrect because there is no specified timeline for stopping nicotine gum use. Choice C is incorrect because nicotine gum is not recommended during pregnancy. Choice D is incorrect as the client should chew the nicotine gum slowly for about 30 minutes, not quickly for 15 minutes.

4. A client has a new prescription for transdermal patches. Which of the following statements should the nurse identify as an indication that the client understands the instructions?

Correct answer: C

Rationale: The correct answer is C because applying the patch to an area of skin without hair ensures better absorption of the medication. Hair can interfere with the patch's adherence and effectiveness. It is important for the client to choose a clean, hairless area for proper medication delivery. Choices A, B, and D are incorrect. Cleaning the site with an alcohol swab is a good practice but does not specifically indicate understanding of proper patch application. Rotating application sites weekly is important to prevent skin irritation but is not directly related to applying the patch to an area of skin without hair. Placing the new patch where the old patch was may lead to skin irritation and poor absorption of the medication.

5. A nurse is providing teaching to a client who has a new prescription for Metoprolol. Which of the following statements should the nurse include?

Correct answer: A

Rationale: Metoprolol, a beta-blocker, can cause dizziness, especially when starting the medication. The nurse should inform the client to change positions slowly to avoid dizziness and falls.
