Which of the following practices is essential for preventing the spread of healthcare-associated infections?
- A. Frequent handwashing
- B. Sharing medical equipment
- C. Reducing patient turnover
- D. Increasing hospital bed capacity
Correct Answer: A
Rationale: The correct answer is A: Frequent handwashing. Handwashing is essential for preventing the spread of healthcare-associated infections as it helps remove and kill harmful bacteria and viruses. By washing hands regularly, healthcare workers can reduce the risk of transmitting infections between patients. Sharing medical equipment (B) can actually increase the spread of infections. Reducing patient turnover (C) can help minimize exposure, but without proper hand hygiene, infections can still spread. Increasing hospital bed capacity (D) is unrelated to preventing infections. Therefore, A is the most effective practice for infection control.

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.
Which nutrient is most critical for preventing neural tube defects during pregnancy?
- A. Iron
- B. Calcium
- C. Folic acid
- D. Vitamin D
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.
Which of the following is a key principle of Primary Health Care (PHC)?
- A. Centralized health planning
- B. Community participation
- C. Focus on specialized care
- D. High technology healthcare
Correct Answer: B
Rationale: The correct answer is B: Community participation. This is a key principle of Primary Health Care (PHC) as it emphasizes involving communities in decision-making, planning, and implementation of healthcare services. Community participation ensures that healthcare services are culturally appropriate, accessible, and meet the specific needs of the population. It also promotes empowerment and ownership of health initiatives within the community.
Centralized health planning (A) goes against the decentralized and community-focused approach of PHC. Focus on specialized care (C) contradicts the comprehensive and holistic nature of PHC. High technology healthcare (D) may not always be feasible or accessible in resource-limited settings, which is a key consideration in PHC implementation.
Which of the following is a major risk factor for cardiovascular diseases?
- A. Low cholesterol levels
- B. Physical inactivity
- C. Low blood pressure
- D. Adequate sleep
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.
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 recommended duration of exclusive breastfeeding is 6 months. This is because breast milk provides all the necessary nutrients for an infant's growth and development in the first 6 months of life. Introducing solid foods too early can increase the risk of infections and allergies. Choice A (3 months) is not ideal as it may not provide sufficient nutrients for the baby's growth. Choices C (9 months) and D (12 months) exceed the recommended duration and may not be necessary for exclusive breastfeeding, as other foods can be introduced after 6 months.
