Which statistic best reflects the nutritional status of a population?

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: D

Rationale: The correct answer is D because as a healthcare provider attending to a delivery, noting the interval, duration, and intensity of labor and contractions is crucial for assessing the progress of labor and ensuring the safety of both the mother and the baby. This information helps in determining if the delivery is progressing normally or if there are any complications that require immediate attention. Setting up a sterile area (choice A) and putting on a clean gown and apron (choice B) are important steps but should come after assessing the labor progress. Cleansing the client's vulva with soap and water (choice C) is not recommended during labor as it can introduce bacteria and increase the risk of infection.

Correct Answer: C

Rationale: The correct answer is C because it directly aligns with the principle of freedom of choice in family planning. Providing couples with adequate information regarding different methods empowers them to make informed decisions based on their preferences and circumstances. This choice respects individual autonomy and allows couples to choose the method that best suits their needs. Incorrect Choices: A: Information dissemination is important but does not necessarily guarantee freedom of choice. B: Supporting research and development is beneficial but does not directly relate to the freedom of choice for couples. D: Encouraging joint responsibility is valuable for promoting communication, but it does not explicitly ensure freedom of choice for individuals.

Correct Answer: C

Rationale: The correct injection site for administering the DPT vaccine to an infant is the vastus lateralis muscle. This site is preferred for infants and young children because it has a larger muscle mass, reducing the risk of hitting a nerve or bone. The vastus lateralis muscle is located on the thigh, making it easily accessible and safe for injecting vaccines. It is recommended by healthcare professionals for infants due to better absorption and reduced discomfort. In contrast, the deltoid muscle is more suitable for adults, the gluteal muscle carries a risk of hitting the sciatic nerve, and the forearm lacks sufficient muscle mass for injection.

Correct Answer: D

Rationale: The correct answer is D because all of the choices can be used to describe the sex composition of the population. A, the sex ratio, compares the number of males to females. B, sex proportion, also refers to the distribution of males and females in a population. C, population pyramid, visually displays the age and sex distribution of a population. Therefore, any of these tools can be utilized to describe the sex composition accurately.

Correct Answer: B

Rationale: The neonatal mortality rate is calculated as the number of neonatal deaths (deaths within the first 28 days of life) divided by the number of live births in a given period, multiplied by 1000. In this case, the number of neonatal deaths is 2 (babies who died less than 4 weeks after birth), and the number of live births is 46 (babies born excluding stillbirths). Therefore, the calculation is (2/46) * 1000 = 43.5/1000. This rate represents the number of neonatal deaths per 1000 live births in Barangay A for that year. Choice B is correct as it accurately represents the neonatal mortality rate based on the information provided. Choices A, C, and D are incorrect as they do not align with the calculation using the specific data given.

Correct Answer: B

Rationale: To calculate the crude death rate, divide the total number of deaths by the total population and then multiply by 1000. In this case, 94 deaths out of 18,000 population is (94/18000)*1000 = 5.2/1000. This is the correct answer (B). Choice A (4.1/1000) is incorrect as it underestimates the death rate. Choice C (6.3/1000) and D (7.3/1000) are both overestimations of the death rate based on the given data.

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: 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.
