Which of the following is a key principle of Primary Health Care (PHC)?

Correct Answer: B

Rationale: The correct answer is B: Community participation. This is a key principle of Primary Health Care (PHC) as it emphasizes involving communities in decision-making, planning, and implementation of healthcare services. Community participation ensures that healthcare services are culturally appropriate, accessible, and meet the specific needs of the population. It also promotes empowerment and ownership of health initiatives within the community. Centralized health planning (A) goes against the decentralized and community-focused approach of PHC. Focus on specialized care (C) contradicts the comprehensive and holistic nature of PHC. High technology healthcare (D) may not always be feasible or accessible in resource-limited settings, which is a key consideration in PHC implementation.

Correct Answer: C

Rationale: Secondary prevention aims to detect and treat a disease in its early stages to prevent complications. Screening for hypertension (Choice C) is an example as it involves identifying individuals at risk of developing high blood pressure-related issues. Vaccination (Choice A) is a form of primary prevention. Health education (Choice B) is more focused on promoting healthy behaviors. Rehabilitation therapy (Choice D) is part of tertiary prevention, aimed at improving function after a disease has occurred.

Correct Answer: D

Rationale: The correct answer is D: To provide couples with the information and means to control fertility. This is because the primary aim of the Family Planning Program is to empower individuals with the knowledge and resources to make informed decisions about family size and spacing. This includes access to contraceptives, education about reproductive health, and support for family planning choices. A: To improve infant nutrition - This is not the primary aim of the Family Planning Program, although family planning can indirectly contribute to better infant nutrition by spacing births appropriately. B: To reduce maternal mortality - While family planning can help reduce maternal mortality by preventing unintended pregnancies and unsafe abortions, it is not the primary aim of the program. C: To prevent sexually transmitted infections - Although promoting safe sex practices is important in family planning, preventing STIs is not the primary aim of the program.

Correct Answer: C

Rationale: The correct answer is C: Antiretroviral therapy. This is a key strategy because it involves giving HIV medications to the mother during pregnancy, labor, and delivery, as well as to the newborn, significantly reducing the risk of transmission. Antiretroviral therapy helps lower the viral load in the mother's body, making it less likely for the virus to be passed on to the child. Exclusive breastfeeding (choice A) can increase the risk of transmission, routine immunization (choice B) does not directly prevent mother-to-child transmission of HIV, and nutritional supplementation (choice D) is not a primary strategy for preventing transmission.

Correct Answer: C

Rationale: The correct answer is C: Infant mortality rate. This indicator reflects the number of infants who die before reaching one year of age per 1,000 live births. It is a crucial measure of the overall health of a population as it reflects the quality of healthcare, nutrition, and living conditions. High infant mortality rates indicate poor health outcomes and inadequate healthcare services. A: Literacy rate is not directly related to measuring the health status of a population. B: GDP measures the economic performance of a country and does not directly reflect the health status of its population. D: Employment rate is an indicator of the labor market situation, not specifically related to health status measurement.
