Correct Answer: C

Rationale: The correct answer is C. Demonstrating the wound care procedure correctly indicates the client's readiness to independently manage wound care. This action shows practical understanding and application of the necessary skills. Choice A, asking relevant questions, is important but does not directly demonstrate the ability to perform the procedure. Choice B, stating the ability to complete the regimen, is a good intention but does not confirm practical competence. Choice D, having necessary supplies, is essential but does not ensure the client's ability to execute proper wound care.

Correct Answer: A

Rationale: The correct answer is A. Clients taking warfarin need to be consistent with their vitamin K intake to maintain a balance in blood clotting. Avoiding foods high in vitamin K is essential as they can interfere with the medication's effectiveness. Choices B, C, and D are all correct statements regarding warfarin therapy. Regular blood testing to monitor INR levels ensures the medication is working effectively, taking the medication at the same time daily maintains a consistent level in the bloodstream, and using a soft toothbrush helps prevent gum bleeding due to warfarin's anticoagulant effects.

Correct Answer: A

Rationale: When communicating with a client who is hearing impaired, it is important to face the client and speak slowly. This helps the individual lip-read and understand the communication more easily. Speaking loudly can distort speech and make it harder for the person to understand. Written communication may not always be practical or accessible for the client, especially in real-time interactions. Gestures and body language can actually aid in communication by providing visual cues and context. Therefore, the best approach is to face the client, speak clearly at a moderate pace, and use gestures and body language to enhance understanding.

Correct Answer: A

Rationale: When encountering an unfamiliar medication, the safest action for a nurse is to consult the medication reference book available on the unit. This resource provides accurate and detailed information about medications, including indications, dosages, side effects, and nursing considerations. Administering a medication without understanding it (choice B) can lead to medication errors and harm to the client. Asking a colleague for information (choice C) may not always provide accurate or up-to-date information. Contacting the provider (choice D) should be reserved for situations where immediate clarification is needed, but consulting the reference book is the initial step to gain knowledge and ensure safe medication administration.

Correct Answer: C

Rationale: The correct answer is C: "This test will provide information about the function of your liver." Alanine aminotransferase (ALT) is an enzyme mainly found in the liver. An elevated ALT level may indicate liver damage or disease. Choices A, B, and D are incorrect because ALT is specifically related to liver function and not indicative of blood clot risk, heart performance, or kidney function.
