Which of the following is a major risk factor for cardiovascular diseases?

Correct Answer: B

Rationale: The correct answer is B: Physical inactivity. Physical inactivity is a major risk factor for cardiovascular diseases because regular exercise helps maintain a healthy heart and blood vessels. It reduces the risk of developing conditions like high blood pressure, high cholesterol, and obesity, which are all linked to cardiovascular diseases. In contrast, choices A, C, and D are not major risk factors for cardiovascular diseases. Low cholesterol levels (A) are usually considered beneficial for heart health, low blood pressure (C) is generally a sign of good cardiovascular health, and while adequate sleep (D) is important for overall well-being, it is not directly linked to cardiovascular diseases.

Correct Answer: C

Rationale: The correct answer is C: Ensuring skilled attendance at birth. This is a key component of the Safe Motherhood Initiative as it focuses on providing trained healthcare professionals during childbirth to reduce maternal and neonatal mortality rates. This ensures that complications during labor can be promptly identified and managed, improving outcomes for both mother and baby. A: Promoting exclusive breastfeeding is important for infant health but is not specifically a component of the Safe Motherhood Initiative. B: Providing routine immunizations is crucial for child health but not directly related to maternal care during childbirth. D: Offering genetic counseling is valuable for families at risk of genetic disorders but is not a primary focus of the Safe Motherhood Initiative.

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: B

Rationale: The correct answer is B: To boost the immune system. Vitamin A is essential for maintaining a healthy immune system by supporting the production and function of white blood cells. This helps the body fight off infections and illnesses. Administering Vitamin A to children can help prevent deficiencies and strengthen their immune response. Explanation of why the other choices are incorrect: A: Vitamin D is more closely associated with improving bone health, not Vitamin A. C: Cognitive development is primarily influenced by nutrients like iron and omega-3 fatty acids, rather than Vitamin A. D: Anemia is usually prevented by iron supplementation, not Vitamin A.

Correct Answer: A

Rationale: The correct answer is A: Maternal HIV infection. Breastfeeding is contraindicated in mothers with HIV due to the risk of transmission to the infant through breast milk. HIV can be transmitted through breast milk even if the mother is on antiretroviral therapy. Maternal diabetes, anemia, and hypertension are not contraindications for breastfeeding as long as they are well managed. Breastfeeding is actually beneficial in managing diabetes and anemia. Hypertensive mothers can breastfeed unless there are complications that require specific medications that may be unsafe for the infant.

Correct Answer: B

Rationale: The correct answer is B: Children aged 1-4 years. This age group is most vulnerable to PEM due to their rapid growth and development, high energy requirements, and dependency on caregivers for nutrition. Infants below 6 months are typically protected by breast milk, adolescents have lower risk due to fewer growth demands, and elderly are more at risk for other types of malnutrition. Therefore, children aged 1-4 years are the most vulnerable to PEM.

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: 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 correct answer is C: Prevention and treatment of childhood illnesses. The IMCI strategy focuses on a holistic approach that includes both prevention and treatment of common childhood illnesses. It emphasizes promoting healthy practices, early detection, appropriate treatment, and follow-up care. Hospital-based care (A) is not the primary focus as IMCI aims to improve health outcomes at the community level. Curative care only (B) is also not correct as prevention is a key component of IMCI. Surgical interventions (D) are not the primary focus of IMCI, which aims to address a wide range of common childhood illnesses with a comprehensive approach.
