Correct Answer: A

Rationale: The correct answer is A: 'higher in Barangay C than in Barangay B.' This is because Barangay C had more cases of ARI (20) compared to Barangay B (15). Therefore, the total number of children who have ARI is higher in Barangay C. Choices B and C are incorrect because the data clearly shows that Barangay C had more cases than Barangay B. Choice D is also incorrect as there is sufficient data provided to compare the number of ARI cases between the two barangays.

Correct Answer: B

Rationale: The availability of healthcare services is a critical factor in determining community health. While the number of hospitals may contribute to healthcare accessibility, it is the overall availability of healthcare services that encompasses various factors including hospitals, clinics, healthcare providers, and resources. Socioeconomic status and population density are important determinants of health outcomes, but the direct availability of healthcare services plays a more immediate and direct role in promoting community health.

Correct Answer: A

Rationale: The correct answer is A. Audible wheezing and grunting in an infant indicate respiratory distress, which is a critical condition requiring immediate assessment and intervention by the healthcare provider. Choices B, C, and D do not present with immediate life-threatening conditions that require urgent evaluation. Soot on the face and shirt, second-degree burns on the hand, and singed hair, while concerning, do not pose an immediate threat to life compared to respiratory distress in an infant.

Correct Answer: C

Rationale: The correct answer is the 60-year-old homeless person who is an alcoholic and smokes. This individual has the highest risk of developing community-acquired pneumonia due to factors such as homelessness, alcoholism, and smoking, which weaken the immune system and make them more susceptible to respiratory infections. Choice A is incorrect as working with underprivileged children, while potentially exposing the individual to various illnesses, does not directly increase the risk of pneumonia. Choice B is less likely as exercise-induced wheezing may suggest asthma but does not directly correlate with pneumonia risk. Choice D, an aerobics instructor who eats only vegetables and skips meals, does not have the same level of risk factors for pneumonia as the homeless person in choice C.

Correct Answer: B

Rationale: The correct answer is to select the best strategy for health action for people to implement because it empowers the community to take ownership of their health. Listening to people's problems (Choice A) is important, but the effectiveness lies in empowering them to implement solutions. Directing people's efforts (Choice C) can be directive and may not foster community ownership. Just telling clients what to do (Choice D) does not promote active participation and empowerment.
