Correct Answer: A

Rationale: The best activity to engage participants in a community health fair promoting mental health awareness is to offer free mental health screenings. This activity not only attracts participants but also provides them with immediate, valuable information about their mental health status. Free screenings can help raise awareness, encourage early detection of mental health issues, and prompt participants to seek further assistance if needed. Lectures, while informative, may not be as engaging or impactful as the personalized feedback individuals receive from screenings. Distributing resources is helpful, but active engagement through screenings is more effective in promoting awareness and encouraging action. Interactive workshops on stress management are beneficial but might not provide the same level of individualized insight into mental health as screenings do.

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: D

Rationale: The correct answer is D. Drinking 240 mL of fluid five times during the shift indicates a fluid intake of 1200 mL, which exceeds the minimum objective of at least 1000 mL. The client meeting or exceeding the fluid intake goal is a clear indicator of a successful outcome. Choices A, B, and C are incorrect because simply drinking adequate fluids, voiding without difficulty, or feeling less thirsty do not directly demonstrate meeting the specific objective of fluid intake set in the care plan.

Correct Answer: B

Rationale: The correct answer is B: higher rates of condom use among teenagers. This outcome indicates that the teenagers are adopting safer sexual practices, which can effectively reduce the incidence of STIs. Increased attendance at educational sessions (Choice A) may show interest but does not directly reflect behavior change. More teenagers seeking testing for STIs (Choice C) indicates awareness but not necessarily prevention. Greater knowledge of STI prevention methods (Choice D) is valuable but does not guarantee behavioral change like increased condom use.

Correct Answer: C

Rationale: A temperature of 99°F (37.2°C) in a postoperative client requires immediate intervention as it may indicate the presence of infection. Elevated temperature post-surgery can be a sign of surgical site infection or systemic infection, which can lead to serious complications if not addressed promptly. Monitoring and managing a fever in a postoperative client is crucial to prevent further complications. The other findings, such as a heart rate of 90 beats per minute, oxygen saturation of 92%, and pain at the surgical site, are common postoperative assessments that may not necessarily require immediate intervention unless they are significantly out of normal range or causing severe distress to the client.
