In a mother's class, you discuss proper breastfeeding technique. Which of these is a sign that the baby has latched on the breast properly?

Correct Answer: B

Rationale: The correct answer is B because if the mother does not feel nipple pain, it indicates that the baby has latched on properly. Nipple pain is a common sign of improper latch, which can lead to discomfort and ineffective breastfeeding. The other choices are incorrect: A indicates ineffective sucking, C suggests a shallow latch, and D signifies a shallow latch that only involves the nipple, not the areola, leading to potential issues with milk transfer and nipple pain.

Correct Answer: B

Rationale: The correct answer is B: Vitamin A. During measles, Vitamin A supplementation is crucial to reduce the risk of complications and improve recovery. Vitamin A deficiency is common in children with measles and can lead to severe outcomes. Tetanus toxoid (A) is not indicated in measles treatment. Vitamin D (C) and Vitamin E (D) do not play a significant role in managing measles symptoms. In summary, Vitamin A is essential for children with measles to prevent complications and support recovery, making it the correct choice among the options provided.

Correct Answer: A

Rationale: The correct answer is A: Immunization coverage. This is the most effective measure as it ensures a high percentage of the population is vaccinated, leading to herd immunity. This reduces the spread of diseases. Cold chain (B) ensures vaccine quality but doesn't directly control disease occurrence. Potency of vaccines (C) is important but doesn't address population coverage. Health education (D) is valuable but doesn't directly prevent disease spread like high immunization coverage does.

Correct Answer: D

Rationale: Step 1: Define false negative - An individual with the disease incorrectly identified as disease-free. Step 2: Understand sensitivity - Ability to correctly identify individuals with the disease. Step 3: False negatives indicate low sensitivity. Step 4: Sensitivity is a key characteristic of a diagnostic test. Step 5: Therefore, the correct answer is D: Sensitivity. Summary: A: Effectiveness - Overall ability of the test to achieve its intended purpose. B: Efficacy - Ability of the test under ideal conditions. C: Specificity - Ability to correctly identify individuals without the disease. D: Sensitivity - Ability to correctly identify individuals with the disease.

Correct Answer: A

Rationale: The correct answer is A: 1-4 year old age-specific mortality rate. This statistic reflects the overall health and nutritional status of a population by focusing on a specific age group vulnerable to malnutrition-related issues. It provides a comprehensive view of the impact of nutrition on child health and development. Proportionate mortality rate (B) measures the distribution of causes of death, not specifically related to nutrition. Infant mortality rate (C) focuses on deaths within the first year of life, which may not fully capture the nutritional status of the whole population. Swaroop's index (D) assesses life expectancy and income level, but does not directly measure nutritional status.

Correct Answer: A

Rationale: The correct answer is A: 265. To estimate the number of pregnant women receiving tetanus toxoid during an outreach activity, we can use the average prevalence rate of 17.7 pregnant women per 1,000 population. So, 1,500 * 17.7 / 1,000 = 26.55, which rounds to 27 pregnant women. Since the population is 1,500, we can estimate that around 27 * 10 = 270 pregnant women. However, not all pregnant women may attend the activity, so we can further estimate that around 270 * 0.98 = 265 pregnant women will likely receive tetanus toxoid. Summary of other choices: B: 300 - Overestimates the number of pregnant women likely to receive tetanus toxoid. C: 375 - Overestimates even more, not a reasonable estimate based on the given population. D: 400 - Significantly overestimates the number

Correct Answer: A

Rationale: The correct answer is A: Crude birth rate. Natality rate refers to the number of live births per 1,000 people in a population per year. The crude birth rate includes all live births in a population without any adjustments. B: Neonatal mortality rate measures the number of deaths within the first 28 days of life per 1,000 live births. C: Infant mortality rate measures the number of deaths within the first year of life per 1,000 live births. D: General fertility rate measures the number of live births per 1,000 women of childbearing age.

Correct Answer: B

Rationale: The correct answer is B: Vastus lateralis muscle. The vastus lateralis is a recommended site for administration of DPT vaccine in infants and young children. It is a large muscle located in the thigh, providing a well-developed area for injection with minimal risk of hitting nerves or blood vessels. The site is easily accessible, especially for parents or caregivers administering the vaccine. Choice A (Deltoid muscle) is more commonly used in adults, not preferred for infants. Choices C (Gluteus maximus muscle) and D (Abdomen) are not recommended sites for DPT vaccine administration due to potential risk of hitting sciatic nerve in the gluteal region and abdominal organs in the abdomen, respectively.

Correct Answer: D

Rationale: The correct answer is D because individuals who have had a delivery within the past 15 months are at higher risk for closely spaced pregnancies, which may pose health risks for both the mother and the newborn. It is crucial to allow the body to recover adequately between pregnancies to reduce maternal and infant mortality rates. Choices A, B, and C do not specifically address the need for spacing pregnancies and do not highlight the increased health risks associated with closely spaced pregnancies.
