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: A survey, specifically a sample survey, is the most appropriate method for gathering data about a sample of the population. In this scenario, focusing on families with members who are part of the target population for PEM requires collecting specific data from a subset of the overall population, making a survey the best choice for this purpose.

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.

Correct Answer: A

Rationale: The correct interval between doses of tetanus toxoid for pregnant women is 4 weeks. This interval ensures that pregnant women receive adequate protection against tetanus, particularly in areas where the disease is prevalent. The 4-week interval helps in building and maintaining immunity to protect both the pregnant woman and her developing baby from tetanus infection.

Correct Answer: D

Rationale: Intersectoral linkages involve collaborations between the health sector and other sectors for community development. In this scenario, cooperation between a public health nurse (PHN) and a public school teacher exemplifies intersectoral linkages, as it represents a partnership between the health and education sectors.
