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 diseases is targeted for eradication through the Expanded Program on Immunization (EPI)?
- A. Hepatitis B
- B. Diphtheria
- C. Poliomyelitis
- D. Tuberculosis
Correct Answer: C
Rationale: The correct answer is C: Poliomyelitis. The EPI targets diseases for eradication through vaccination programs. Polio is a priority due to its devastating effects and the effectiveness of the polio vaccine. Hepatitis B (A) is not currently targeted for eradication. Diphtheria (B) and Tuberculosis (D) are controlled through vaccination and treatment but are not targeted for global eradication efforts.
What is the purpose of a community needs assessment?
- A. To diagnose individual health conditions
- B. To identify and prioritize community health needs
- C. To evaluate the effectiveness of a treatment plan
- D. To provide emergency medical services
Correct Answer: B
Rationale: The purpose of a community needs assessment is to identify and prioritize the health needs of a community as a whole, not individual health conditions. This process helps in understanding the specific issues affecting the community and guides the development of effective intervention strategies. Evaluating treatment plans or providing emergency medical services is not the primary goal of a needs assessment. Therefore, option B is correct as it aligns with the main objective of assessing community health needs.
Which of the following is a common sign of dehydration in infants?
- A. Frequent urination
- B. Sunken fontanelle
- C. Excessive drooling
- D. Increased appetite
Correct Answer: B
Rationale: The correct answer is B: Sunken fontanelle. Dehydration in infants can cause the fontanelle, the soft spot on the baby's head, to appear sunken. This is due to decreased fluid levels in the body. Sunken fontanelle is a common and easily identifiable sign of dehydration in infants. The other choices are incorrect because frequent urination is not typically associated with dehydration in infants, excessive drooling can be a normal part of teething, and increased appetite is not a specific sign of dehydration in infants.
Which of the following is an example of a live attenuated vaccine?
- A. Hepatitis B vaccine
- B. Inactivated polio vaccine
- C. Measles, Mumps, Rubella (MMR) vaccine
- D. Diphtheria, Tetanus, Pertussis (DPT) vaccine
Correct Answer: C
Rationale: The correct answer is C: Measles, Mumps, Rubella (MMR) vaccine. Live attenuated vaccines contain weakened forms of the virus. MMR vaccine is made from weakened live viruses of measles, mumps, and rubella. When administered, the body develops an immune response without causing the disease. Choice A, Hepatitis B vaccine, is a subunit vaccine. Choice B, Inactivated polio vaccine, is a killed virus vaccine. Choice D, Diphtheria, Tetanus, Pertussis (DPT) vaccine, is a toxoid vaccine. Live attenuated vaccines provide stronger and longer-lasting immunity as they mimic natural infection without causing illness.
Which of the following is an essential component of prenatal care?
- A. Routine immunizations
- B. Nutritional counseling
- C. Surgical interventions
- D. Radiologic exams
Correct Answer: B
Rationale: The correct answer is B: Nutritional counseling. Prenatal care focuses on ensuring the health of both the mother and the developing baby. Proper nutrition is essential for the well-being of both, as it supports the baby's growth and development and helps prevent complications for the mother. Nutritional counseling provides guidance on maintaining a balanced diet, taking necessary supplements, and managing any dietary restrictions during pregnancy. Routine immunizations (A) are important but not typically a primary component of prenatal care. Surgical interventions (C) and radiologic exams (D) are generally avoided during pregnancy unless absolutely necessary due to potential risks to the fetus. Therefore, B is the most essential component for prenatal care.
