Correct Answer: D

Rationale: The correct answer is 'D: health promotion.' Health promotion strategies are aimed at helping individuals reduce the risk of illness and maintain their maximum level of function by emphasizing preventive measures, healthy behaviors, and lifestyle choices. Illness prevention (choice A) focuses on specific actions to avoid illness but may not necessarily address overall function. Crisis intervention (choice B) refers to immediate assistance during emergencies rather than long-term prevention. Rehabilitation (choice C) involves restoring function after illness or injury rather than primarily focusing on preventive measures and maintaining maximum function.

Correct Answer: B

Rationale: PCA allows patients to self-administer pain medication within prescribed limits, without the need to call the nurse before taking an additional dose. Choice B suggests a misunderstanding of how PCA works, as the patient should be educated that they can self-administer doses within the safety parameters set by the healthcare provider. Choices A, C, and D demonstrate proper understanding of PCA, hence are not indicative of needing further teaching.

Correct Answer: B

Rationale: Community health nursing primarily focuses on preventive measures and promoting overall health within a community. Choice A is incorrect as treatment is not the main emphasis. Choice C is incorrect as identification and assessment are steps that may be involved but not the main focus. Choice D is incorrect as it refers to the illness end rather than the preventive end of the wellness-illness continuum.

Correct Answer: D

Rationale: The correct answer is 'D' because all the listed factors - cigarette smoking, a parent with adult-onset diabetes, and exposure to toxic substances in the workplace - can individually influence a person's health status. Cigarette smoking directly impacts health by increasing the risk of various diseases. Having a parent with adult-onset diabetes can also influence one's health due to genetic predisposition and lifestyle factors. Exposure to toxic substances in the workplace can lead to health issues. Choices A, B, and C are not mutually exclusive but rather represent different aspects of individual influences on health status, making 'D' the most comprehensive and accurate answer.

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.
