The nursing staff has attempted to screen the entire African American population in the community for diabetes. Which of the following would provide immediate verification of the success of the nursing staff’s efforts?

Correct Answer: D

Rationale: The correct answer is D because a decrease in the prevalence of diabetes in the community would indicate that the nursing staff's efforts to screen the African American population for diabetes have been successful. This is because a decrease in prevalence shows that fewer people in the community have diabetes, suggesting that early detection and intervention have led to a lower overall burden of the disease. A, B, and C are incorrect because: A: An epidemic of diabetes would not verify the success of the nursing staff's efforts, as it indicates a widespread outbreak rather than successful screening efforts. B: This option is incomplete and does not provide a logical outcome related to the screening efforts. C: An increase in the incidence of diabetes would suggest a worsening situation, not the success of the screening efforts.

Correct Answer: B

Rationale: Step 1: Introduction of heart-healthy curriculum in first grade instills early awareness and habits. Step 2: Presentations on diet and exercise educate the community on preventive measures. Step 3: Special education sessions for high-risk populations target those most vulnerable. Summary: Choice A lacks specificity and targeted approach. Choice C focuses mainly on online activities, lacking community engagement. Choice D includes some good elements but lacks a comprehensive and early intervention approach like Choice B.

Correct Answer: B

Rationale: The correct answer is B: The positive predictive value of mammography. The nurse needs to know the probability that a positive mammogram result truly indicates the presence of cancer in this specific woman. Understanding the positive predictive value will help the nurse provide accurate information and emotional support to the woman. Choice A (negative predictive value) is not relevant as the woman has a positive result. Choice C (reliability) and D (validity) are important but do not address the specific concern of the woman about the likelihood of having cancer based on a positive result.

Correct Answer: D

Rationale: The correct answer is D: Encourage the parents to enroll their sons in Cub Scouts. The nurse should recommend this because Cub Scouts can provide a positive and enriching experience for the boys in terms of social skills, character development, and physical activities. It is relevant to the children's overall well-being and can contribute to their growth and development. Option A is incorrect as it does not address the benefits of joining Cub Scouts. Option B is incorrect as it discourages enrollment without considering the potential positive impact. Option C is incorrect as it dismisses the relevance of Cub Scouts without considering its potential benefits for the children.

Correct Answer: C

Rationale: The correct answer is C: Host factors. Host factors refer to individual characteristics that influence susceptibility to an infection. In this case, some people exposed to the bacteria may have stronger immune systems or other genetic predispositions that make them more resistant to the illness. This explains why only some individuals become ill despite exposure. A: Chemical agent factors are not relevant in this scenario as the question focuses on the individual's response to the bacteria rather than specific chemicals involved. B: Environmental factors may play a role in the spread of the bacteria but do not explain why only some individuals become ill. D: Physical agent factors typically refer to physical forces causing injury, which are not directly applicable to a bacterial illness scenario.
