What is the purpose of a population pyramid?
- A. To show the distribution of income levels
- B. To illustrate the age and sex composition of a population
- C. To compare the incidence of diseases
- D. To display the literacy rates
Correct Answer: B
Rationale: The correct answer is B: To illustrate the age and sex composition of a population. Population pyramids graphically represent the age and gender structure of a population, showing the distribution of different age groups and genders within a population at a specific point in time. This information is crucial for policymakers and demographers to understand population dynamics, such as birth rates, life expectancy, and potential workforce size.
Choice A (To show the distribution of income levels) is incorrect because income levels are not typically depicted in a population pyramid. Choice C (To compare the incidence of diseases) is incorrect because population pyramids do not provide information on disease prevalence. Choice D (To display the literacy rates) is incorrect as literacy rates are also not typically included in population pyramids.

Which nutrient is essential for preventing anemia in pregnant women?
- A. Vitamin C
- B. Vitamin D
- C. Iron
- D. Calcium
Correct Answer: C
Rationale: The correct answer is C: Iron. Iron is essential for preventing anemia in pregnant women because it is a key component of hemoglobin, the protein in red blood cells that carries oxygen to tissues and organs. During pregnancy, the demand for iron increases to support the growing fetus and the mother's increased blood volume. Without adequate iron intake, pregnant women are at a higher risk of developing iron-deficiency anemia, which can lead to complications for both the mother and the baby.
Other choices are incorrect because:
A: Vitamin C is important for iron absorption but does not directly prevent anemia.
B: Vitamin D is important for bone health but does not prevent anemia.
D: Calcium is important for bone health but does not prevent anemia in pregnant women.
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 correct answer is C: 12 months. The first dose of the MMR vaccine is typically administered at 12 months of age because this is when a child's immune system is more developed to respond effectively to the vaccine. Administering it earlier may not provide adequate protection. Choice A (At birth) is incorrect because newborns have maternal antibodies that can interfere with the vaccine's efficacy. Choice B (6 months) is too early as infants need time to develop their immune system. Choice D (18 months) is also incorrect as delaying the vaccine may leave the child vulnerable to diseases like measles, mumps, and rubella.
Which of the following is a benefit of antenatal care?
- A. Early detection of pregnancy complications
- B. Increased risk of preterm labor
- C. Decreased maternal weight gain
- D. Delayed fetal growth
Correct Answer: A
Rationale: The correct answer is A: Early detection of pregnancy complications. Antenatal care involves regular check-ups during pregnancy to monitor the health of both the mother and the baby. Early detection of pregnancy complications through antenatal care allows for timely intervention and management, reducing the risks to both the mother and the baby. This can help prevent serious complications and improve outcomes.
Incorrect choices:
B: Increased risk of preterm labor - Antenatal care aims to reduce the risk of preterm labor through monitoring and appropriate management.
C: Decreased maternal weight gain - Antenatal care focuses on ensuring appropriate weight gain for a healthy pregnancy.
D: Delayed fetal growth - Antenatal care helps monitor fetal growth and detect any issues early to prevent delayed growth.
Which of the following practices is part of the Baby-Friendly Hospital Initiative (BFHI)?
- A. Promoting the use of infant formula
- B. Encouraging skin-to-skin contact after birth
- C. Separating mother and baby after delivery
- D. Scheduling feedings at fixed intervals
Correct Answer: B
Rationale: The correct answer is B: Encouraging skin-to-skin contact after birth. This practice is part of the Baby-Friendly Hospital Initiative (BFHI) as it promotes bonding, initiates breastfeeding, and helps regulate the baby's temperature and breathing. Skin-to-skin contact also supports the establishment of breastfeeding and enhances maternal-infant attachment.
Incorrect Choices:
A: Promoting the use of infant formula - This goes against the BFHI, which promotes exclusive breastfeeding.
C: Separating mother and baby after delivery - BFHI encourages keeping mother and baby together to promote bonding and breastfeeding.
D: Scheduling feedings at fixed intervals - BFHI promotes feeding on demand to support breastfeeding and responsive feeding practices.
Which of the following is an example of a waterborne disease?
- A. Hepatitis A
- B. Influenza
- C. Measles
- D. Tuberculosis
Correct Answer: A
Rationale: The correct answer is A: Hepatitis A. Waterborne diseases are caused by pathogens that are transmitted through contaminated water. Hepatitis A is a viral infection that spreads through the consumption of contaminated water or food. It affects the liver and is commonly associated with poor sanitation and hygiene. Influenza, Measles, and Tuberculosis are not waterborne diseases. Influenza and Measles are viral infections spread through respiratory droplets, while Tuberculosis is a bacterial infection primarily transmitted through the air. Hepatitis A is the only choice that aligns with the definition of a waterborne disease.
