1. Which nutrient is essential for preventing anemia in pregnant women?
- A. Vitamin C
- B. Vitamin D
- C. Iron
- D. Calcium
Correct answer: C
Rationale: Iron is crucial for preventing anemia in pregnant women because it is needed for the production of hemoglobin, the protein in red blood cells that carries oxygen. During pregnancy, a woman's blood volume increases to support the baby's growth, making iron even more critical to prevent anemia, a condition characterized by a lack of healthy red blood cells. Anemia can lead to fatigue, weakness, and other complications for both the mother and the developing baby. Therefore, ensuring an adequate intake of iron-rich foods or supplements is vital for the health and well-being of pregnant women.
2. At what age is the first dose of the MMR vaccine typically administered to a child?
- A. At birth
- B. 6 months
- C. 12 months
- D. 18 months
Correct answer: C
Rationale: The first dose of the MMR vaccine is typically administered to a child at 12 months of age to provide protection against measles, mumps, and rubella. Administering the vaccine at this age ensures that the child's immune system is developed enough to generate a protective response to the vaccine.
3. Which of the following is NOT a component of Primary Health Care (PHC)?
- A. Community participation
- B. Use of appropriate technology
- C. Equitable distribution of resources
- D. Exclusive focus on curative care
Correct answer: D
Rationale: Primary Health Care (PHC) is a comprehensive approach that includes preventive, promotive, curative, and rehabilitative care. It focuses on prevention, community participation, equitable distribution of resources, and the use of appropriate technology to address health needs. Exclusively focusing on curative care goes against the holistic nature of PHC.
4. Which of the following is an example of a preventive measure in public health?
- A. Chemotherapy
- B. Vaccination
- C. Radiation therapy
- D. Surgical intervention
Correct answer: B
Rationale: Vaccination is a preventive measure used in public health to protect against infectious diseases by stimulating the immune system to develop immunity without causing the disease. It helps prevent the spread of infectious diseases within communities and is a cost-effective way to reduce the burden of illnesses.
5. What is the recommended duration of exclusive breastfeeding?
- A. 3 months
- B. 6 months
- C. 9 months
- D. 12 months
Correct answer: B
Rationale: The World Health Organization recommends exclusive breastfeeding for the first 6 months of a child's life. During this time, breast milk provides all the necessary nutrients for the baby's growth and development, offering protection against infections and supporting optimal health outcomes. After 6 months, complementary foods can be introduced while continuing breastfeeding up to 2 years of age or beyond.
