A public health nurse is evaluating a program designed to reduce childhood obesity. Which outcome indicates that the program is successful?

Correct Answer: C

Rationale: The correct answer is C: reduced rates of childhood obesity. A reduction in childhood obesity rates is a direct indicator that the program is successful in achieving its goal. Increased participation in physical activities (choice A) and higher attendance at nutrition education sessions (choice B) are positive outcomes, but they do not directly measure the program's effectiveness in reducing obesity. Greater knowledge of healthy eating habits (choice D) is important but does not guarantee a decrease in obesity rates. Therefore, the most significant outcome to determine the success of a childhood obesity reduction program is a reduction in obesity rates.

Correct Answer: D

Rationale: The drainage of clear, pale yellow fluid from the chest tube is an indication of proper chest tube functioning. Clear, pale yellow fluid signifies normal drainage from the pleural space without any signs of infection or complications. Choices A, B, and C are incorrect because continuous bubbling in the water-seal chamber, no fluctuation in the water-seal chamber, and intermittent bubbling in the suction control chamber are all indications of potential issues or malfunctioning of the chest tube system, which would require further assessment and intervention.

Correct Answer: A

Rationale: The correct intervention for a client with a history of deep vein thrombosis (DVT) and unilateral leg swelling is to elevate the affected leg on a pillow. Elevating the affected leg helps reduce swelling and pain by promoting venous return and preventing stasis of blood flow. Applying a warm compress (Choice B) may increase inflammation and worsen the condition. Performing passive range-of-motion exercises (Choice C) and encouraging ambulation (Choice D) can dislodge a clot and lead to potential embolism, making these choices contraindicated in a client with DVT.

Correct Answer: B

Rationale: The correct answer is B: Organizing free cholesterol screenings. This intervention is crucial because it helps identify individuals at risk for heart disease by assessing their cholesterol levels. High cholesterol is a significant risk factor for heart disease, and identifying it early can lead to timely interventions and medical care. Choices A, C, and D, while beneficial for overall health, may not directly address the specific risk factor of high cholesterol associated with heart disease. Distributing educational materials on heart-healthy diets (A) could be helpful in preventing heart disease, but identifying individuals already at risk is a more urgent need. Holding workshops on stress management (C) and partnering with local gyms for fitness classes (D) are important for overall health promotion but may not target the specific risk factor of high cholesterol as directly as organizing cholesterol screenings.

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.
