Which of the following best describes the role of a community health nurse?

Correct Answer: C

Rationale: The correct answer is C because a community health nurse focuses on promoting health and preventing disease within the community through education, advocacy, and preventive care. This role involves working with individuals, families, and communities to improve overall health outcomes. A: Providing acute care in hospitals is incorrect as this is typically the role of hospital nurses, not community health nurses. B: Conducting surgeries is incorrect as this is a task performed by surgeons or operating room nurses, not community health nurses. D: Diagnosing and treating medical conditions is incorrect as this falls under the responsibility of healthcare providers such as physicians or nurse practitioners, not community health nurses.

Correct Answer: D

Rationale: The correct answer is D: Folic acid. Folic acid is essential for preventing neural tube defects because it plays a crucial role in DNA synthesis and cell division, particularly during early fetal development. Adequate folic acid intake before and during pregnancy can significantly reduce the risk of neural tube defects. Iron (A), Vitamin C (B), and Calcium (C) are important nutrients for overall health but do not have a direct role in preventing neural tube defects. Iron is vital for red blood cell production, Vitamin C is an antioxidant that supports the immune system, and Calcium is essential for bone health. However, for preventing neural tube defects specifically, folic acid is the essential nutrient.

Correct Answer: B

Rationale: The correct answer is B: Achieving a level of health that enables all people to lead economically productive lives. This is the main focus of WHO's Health For All strategy as it aims to ensure that individuals have good health to actively participate in society and the economy. Choice A is incorrect as the strategy doesn't necessarily focus on providing free healthcare to all individuals, but rather on improving overall health outcomes. Choice C is incorrect as simply building more hospitals and clinics does not address the holistic approach of the Health For All strategy. Choice D is incorrect as increasing the number of healthcare workers is important, but the main focus is on achieving better health outcomes for economic productivity.

Correct Answer: A

Rationale: The correct answer is A: Frequent handwashing. Handwashing is essential for preventing the spread of healthcare-associated infections as it helps remove and kill harmful bacteria and viruses. By washing hands regularly, healthcare workers can reduce the risk of transmitting infections between patients. Sharing medical equipment (B) can actually increase the spread of infections. Reducing patient turnover (C) can help minimize exposure, but without proper hand hygiene, infections can still spread. Increasing hospital bed capacity (D) is unrelated to preventing infections. Therefore, A is the most effective practice for infection control.

Correct Answer: B

Rationale: The correct answer is B: Emphasizes community participation. Primary Health Care is a holistic approach that focuses on involving the community in decision-making and care delivery. This empowers individuals and communities to take charge of their health. Choice A is incorrect as Primary Health Care prioritizes comprehensive and generalist care over specialized care. Choice C is incorrect as Primary Health Care aims to provide care at the grassroots level, not solely relying on hospital-based services. Choice D is incorrect as Primary Health Care places a strong emphasis on preventive measures to promote overall health and well-being.
