Correct Answer: A

Rationale: Immunization coverage is the proportion of the target population that has been immunized. To control the occurrence of diseases effectively, it is crucial that a high percentage of the population is immunized. This not only protects individuals but also helps in achieving herd immunity, reducing the spread of diseases within the community. Therefore, ensuring high immunization coverage is a key strategy in disease prevention and control.

Correct Answer: A

Rationale: The most appropriate statistic to reflect the nutritional status of a population is the 1-4 year old age-specific mortality rate. This age group is highly susceptible to the effects of malnutrition, so a population with poor nutritional status is likely to have a high 1-4 year old age-specific mortality rate, also known as child mortality rate.

Correct Answer: B

Rationale: When a baby has properly latched onto the breast, they take deep, slow sucks, their mouth is wide open, and much of the areola is inside their mouth. A key indicator of a proper latch is that the mother does not feel nipple pain, indicating that the baby is positioned correctly and feeding effectively.

Correct Answer: B

Rationale: Neonatal mortality rate is calculated by dividing the number of babies who died before reaching the age of 28 days by the total number of live births, then multiplying by 1,000. In this case, 2 babies died within 28 days out of 46 total live births. Therefore, the neonatal mortality rate is (2/46) * 1000 = 43.5/1000.
