Which nutrient is most critical for preventing neural tube defects during pregnancy?

Correct Answer: C

Rationale: The correct answer is C: Folic acid. Folic acid is critical for preventing neural tube defects as it is essential for proper development of the neural tube in the fetus. It helps in the formation of the baby's brain and spinal cord. Iron (A) is important for preventing anemia, not neural tube defects. Calcium (B) is crucial for bone health but not directly related to neural tube development. Vitamin D (D) is important for calcium absorption, but not specifically for preventing neural tube defects. Overall, folic acid stands out as the most critical nutrient for this purpose.

Correct Answer: C

Rationale: The primary goal of the Integrated Management of Childhood Illness (IMCI) strategy is to reduce child mortality and morbidity. This strategy focuses on providing holistic care to children, including early detection and treatment of common childhood illnesses. By improving healthcare access and quality, IMCI aims to decrease the number of children dying from preventable diseases. Explanation: A: Reducing the incidence of childhood diseases is important but not the primary goal of IMCI. The strategy is more focused on reducing mortality and morbidity. B: Improving nutritional status is essential for child health but is not the primary goal of IMCI. D: Promoting exclusive breastfeeding is a key component of child health but is not the primary goal of IMCI.

Correct Answer: B

Rationale: The correct answer is B: Vaccination. Preventive measures aim to prevent diseases before they occur. Vaccination helps the immune system recognize and fight specific pathogens, reducing the risk of infection and disease transmission. Chemotherapy (A) is a treatment for cancer, not prevention. Radiation therapy (C) and surgical intervention (D) are also treatments rather than preventive measures. Vaccination stands out as the only option that directly addresses disease prevention, making it the correct choice.

Correct Answer: C

Rationale: The correct answer is C: Vaccination. Vaccination is the most effective method for preventing the spread of infectious diseases because it helps build immunity against specific pathogens, reducing the likelihood of infection and transmission. Vaccines train the immune system to recognize and fight off harmful microorganisms. Antibiotic treatment (A) is used to treat bacterial infections, not prevent the spread of diseases. Quarantine (B) is effective in isolating infected individuals but does not prevent the initial spread of diseases. Nutritional supplementation (D) can support overall health but is not a direct method for preventing infectious diseases.

Correct Answer: C

Rationale: The correct answer is C: Folic acid. Folic acid is essential for fetal development, especially in preventing neural tube defects. It aids in the formation of the neural tube, which develops into the baby's brain and spinal cord. Pregnant women are advised to take folic acid supplements to reduce the risk of these defects. Rationale for other choices: A: Vitamin C - While important for overall health, Vitamin C does not specifically reduce the risk of neural tube defects. B: Vitamin D - Important for bone health, but not directly linked to reducing neural tube defects. D: Iron - Necessary for preventing anemia during pregnancy, but not specifically known to reduce the risk of neural tube defects.

Correct Answer: C

Rationale: Tertiary prevention focuses on managing and improving quality of life for individuals with existing health conditions. Physical rehabilitation programs fall under this category as they help individuals recover and regain functioning after an illness or injury. This intervention aims to prevent further complications and disabilities. Vaccination campaigns (A) and health education seminars (B) are examples of primary and secondary prevention, focusing on preventing diseases before they occur or detecting them early. Early disease screening (D) is also a form of secondary prevention, aiming to detect diseases in their early stages before symptoms appear.

Correct Answer: C

Rationale: The correct answer is C: Community-wide health promotion and disease prevention. Community health nursing focuses on promoting health and preventing diseases within the community as a whole through education, advocacy, and collaboration. This includes addressing social determinants of health and implementing population-based interventions. Choice A is incorrect because community health nursing goes beyond individual patient care. Choice B is incorrect as it is more focused on acute care within hospital settings. Choice D is incorrect as it pertains to specialized medical treatment rather than the broader scope of community health nursing. In summary, the primary focus of community health nursing is on improving the health of the entire community through preventative measures and health promotion initiatives.

Correct Answer: D

Rationale: The correct answer is D: Focusing solely on curative care. The Maternal and Child Health (MCH) program aims to prevent illness and promote health in pregnant women, mothers, infants, and children. Focusing solely on curative care does not align with the preventive and promotive goals of the MCH program. Reducing infant mortality, improving maternal health, and providing family planning services are integral components of the MCH program that aim to enhance the overall well-being of mothers and children. By emphasizing prevention and health promotion, the MCH program aims to address the root causes of health issues rather than solely focusing on treating illnesses after they occur.

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.
