Correct Answer: A

Rationale: The most appropriate advice for an adolescent with acne is to eat a balanced diet for their age. A balanced diet that includes a variety of nutrients is essential for overall health, including skin health. While protein and Vitamin A are important for skin health, focusing solely on increasing these nutrients may not address the overall dietary needs. Similarly, solely decreasing fatty foods or avoiding caffeine may not be the most effective advice for managing acne. Therefore, the best advice is to promote a balanced diet tailored to the adolescent's age.

Correct Answer: C

Rationale: The correct answer is C: health promotion. Health promotion activities involve maintaining a healthy lifestyle to prevent illness. In this scenario, the person is actively engaging in behaviors that promote their overall health and well-being, such as walking and following a healthy diet. Choice A, 'health balance,' is vague and does not specifically address the proactive nature of the person's actions. Choice B, 'disease prevention,' while related, focuses more on specific actions taken to prevent diseases rather than the broader concept of promoting overall health. Choice D, 'self-fulfillment,' does not directly relate to the activities described in the question.

Correct Answer: B

Rationale: The correct answer is B, Incidence. Incidence refers to the number of new cases of a disease in a specific population during a certain time period. Prevalence (choice A) refers to the total number of cases of a disease in a population at a specific point in time. Mortality rate (choice C) is the measure of the number of deaths in a particular population due to a specific cause. Morbidity rate (choice D) is a broader term that encompasses the incidence and prevalence of a disease in a population.

Correct Answer: C

Rationale: Thinning of the skin with loss of elasticity is the physical characteristic of aging that contributes to an increased risk of developing decubitus ulcers. As individuals age, the skin becomes thinner and loses its elasticity, making it more susceptible to damage from pressure, leading to the formation of pressure ulcers. Choices A, B, and D are incorrect as they do not directly contribute to the development of decubitus ulcers in this context.

Correct Answer: B

Rationale: In the context of the PHC approach, programs should be characterized by being managed by community leaders/members (Choice A). This ensures community involvement and ownership. Programs should also be compatible with available resources (Choice C) to be sustainable and effective. Additionally, programs should be developmental in nature (Choice D), focusing on long-term improvements. Choice B is incorrect because programs should not be solely managed by non-government organizations; instead, they should be driven by the community to promote sustainability and empowerment.
