Correct Answer: D

Rationale: The correct answer is 'D: the senior citizen center.' In this scenario, the elderly male client is experiencing unexplained weight loss, which could be indicative of underlying health issues or social isolation. Referring him to the senior citizen center is appropriate as it can provide social support, resources, and programs tailored to address the client's weight loss and overall well-being. Choice A, the adult day care center, is not the most suitable option as the client is still independent and living alone. Choice B, the social security administration office, and Choice C, the women, infants, and children office, are not relevant in this context and do not address the client's specific needs related to weight loss and social support.

Correct Answer: B

Rationale: The correct answer is to suggest the client join a local senior center. Joining a local senior center provides the elderly client with opportunities for social interaction, engagement in activities, and access to support systems, which can significantly help alleviate feelings of isolation and loneliness. Regular visits from a home health aide (Choice A) may provide physical assistance but may not address the client's need for social connection. Referring the client to a support group for seniors (Choice C) is beneficial, but joining a senior center offers a wider range of activities and social opportunities. Recommending a new hobby (Choice D) may be helpful, but the priority should be addressing the client's immediate need for social interaction and support.

Correct Answer: A

Rationale: Offering vaccinations at convenient locations and times is the most effective intervention as it reduces barriers to access and makes it easier for parents to get their children vaccinated. This strategy directly addresses the issue of convenience and accessibility, which are common reasons for low vaccination rates. Distributing educational materials about vaccines (Choice B) can be helpful but may not directly address access issues. Providing incentives for getting vaccinated (Choice C) may be controversial and not sustainable in the long term. Hosting informational sessions for parents (Choice D) can be beneficial for education but may not directly improve vaccination rates as much as increasing access.

Correct Answer: A

Rationale: Surveying employees to determine how many are smoking 2 months after the end of the program provides a direct assessment of the program's effectiveness. This measurement evaluates the actual behavior change related to smoking cessation. Choice B, testing knowledge of OTC nicotine substitute products, does not directly measure smoking cessation outcomes. Choice C relies on self-reporting, which may not be accurate or reliable. Choice D focuses on identifying lifestyle changes but does not directly assess the program's impact on smoking cessation.

Correct Answer: B

Rationale: Dizziness after hemodialysis can indicate hypovolemia, hypotension, or other complications that require immediate intervention to prevent further deterioration or adverse events. Weight gain of 2 pounds may not be immediately concerning post-hemodialysis. A blood pressure of 150/90 mm Hg is slightly elevated but may not require immediate intervention unless accompanied by symptoms. A heart rate of 88 beats per minute falls within the normal range and may not be an immediate cause for concern after hemodialysis.
