Correct Answer: B

Rationale: The correct answer is B: secondary prevention. Secondary prevention involves identifying and addressing issues early to prevent further harm. In this scenario, the nurse is intervening by discussing domestic violence prevention with the client who is showing signs of facial bruising, aiming to prevent further harm even though the client has not disclosed being battered. Choice A (primary prevention) focuses on preventing the onset of a problem before it occurs, like educating about healthy relationships before violence happens. Choice C (tertiary prevention) involves managing and treating the effects of a problem that has already occurred, such as providing counseling to a domestic violence survivor. Choice D (health promotion) aims to enhance well-being and prevent health problems through educational and environmental interventions, which may include aspects of preventing domestic violence, but in this case, the nurse's direct intervention is more about early identification and prevention of harm, aligning it with secondary prevention.

Correct Answer: A

Rationale: The most appropriate advice for an adolescent with acne is to eat a balanced diet for their age. A balanced diet that includes a variety of nutrients is essential for overall health, including skin health. While protein and Vitamin A are important for skin health, focusing solely on increasing these nutrients may not address the overall dietary needs. Similarly, solely decreasing fatty foods or avoiding caffeine may not be the most effective advice for managing acne. Therefore, the best advice is to promote a balanced diet tailored to the adolescent's age.

Correct Answer: B

Rationale: Referring the student for further evaluation of scoliosis is crucial to confirm the diagnosis and determine the appropriate management plan. Sending the student home (choice A) without proper assessment and intervention is not the best course of action. Withdrawing the student from all physical activities (choice C) is not necessary and may cause unnecessary distress. Instructing the student not to carry her backpack on her back (choice D) does not address the underlying issue of scoliosis and is not the most important intervention at this point.

Correct Answer: C

Rationale: The correct answer is C because wound care for a postoperative infection qualifies for Medicare reimbursement. Medicare typically covers skilled nursing care, like wound care, required due to a postoperative infection. Choices A, B, and D involve assessments, teaching, and evaluation, which may not always be eligible for Medicare reimbursement unless they are directly related to skilled nursing care for a specific medical condition.

Correct Answer: C

Rationale: In this scenario, requesting mayors to create a task force is the most effective strategy to improve environmental health conditions in the community. Engaging with local government officials ensures the allocation of resources, coordination of efforts, and the implementation of sustainable solutions. While meeting with youth officials, parents' group leaders, religious and educational leaders are important, involving mayors in creating a task force will lead to broader community involvement and support. Informing local announcers about the project, although helpful for awareness, is not as impactful as engaging with local authorities for tangible change.
