1. Which of the following is an essential nutrient required for preventing neural tube defects?

Correct answer: D

Rationale: Folic acid is a crucial nutrient required for preventing neural tube defects during pregnancy. It plays a vital role in the development of the neural tube in the fetus, reducing the risk of defects such as spina bifida and anencephaly. It is recommended that women of childbearing age consume adequate amounts of folic acid, either through diet or supplements, to support a healthy pregnancy and prevent these serious birth defects.

2. Which of the following is an epidemiologic function of the nurse during an epidemic?

Correct answer: C

Rationale: During an epidemic, nurses play a crucial role in participating in epidemiologic investigations to identify the source of the outbreak. By investigating the source of the epidemic, nurses can help in understanding what caused the outbreak and how it can be controlled and prevented in the future. This function is essential in managing and responding effectively to epidemics.

3. Which of the following is an essential component of a comprehensive antenatal care program?

Correct answer: D

Rationale: A comprehensive antenatal care program should encompass various components to ensure the well-being of the pregnant individual and the fetus. Weight monitoring helps track healthy weight gain during pregnancy, blood pressure measurement is crucial for detecting and managing conditions like preeclampsia, and nutritional counseling supports proper nutrition and healthy development. Including all these components in antenatal care ensures a holistic approach to monitoring and promoting the health of both the mother and the baby.

4. In a municipality with a population of about 20,000, estimate the number of 1-4 year old children who should be given Retinol capsules 200,000 every 6 months.

Correct answer: D

Rationale: To estimate the number of 1-4 year old children in a population, you can multiply the total population by the percentage of children in that age group. In this case, using the Philippine population composition as reference, which is about 11.5% for 1-4 year olds, the calculation would be 20,000 x 0.115 = 2,300 children.

5. Which of the following indicators is used to measure the health status of a population?

Correct answer: C

Rationale: The infant mortality rate is a crucial indicator used to assess the health status of a population. It reflects the number of deaths among infants under one year of age per 1,000 live births. A high infant mortality rate is often indicative of inadequate healthcare services, poor sanitation, and other factors that impact the overall health of a population. Therefore, monitoring and improving the infant mortality rate is essential for evaluating and addressing the health needs of a community.
