What is the interval between tetanus toxoid doses for pregnant women?

Correct Answer: A

Rationale: The correct interval between tetanus toxoid doses for pregnant women is 4 weeks. This short interval ensures optimal immunity for both the mother and the baby against tetanus. Giving the dose every 4 weeks during pregnancy helps maintain the protective levels of antibodies. Waiting longer intervals could decrease the effectiveness of the vaccine and leave the mother and baby vulnerable to tetanus infection. Choices B, C, and D are incorrect because longer intervals between doses may not provide adequate protection and could compromise immunity levels during pregnancy.

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: D

Rationale: The correct answer is D: Lagundi. Lagundi is commonly used for treating fever, headache, and cough due to its anti-inflammatory and analgesic properties. It contains compounds that help reduce inflammation, alleviate pain, and act as a cough suppressant. Sambong (A) is primarily used for kidney disorders, Tsaang gubat (B) is known for its antidiarrheal properties, and Akapulko (C) is used to treat skin diseases. Therefore, Lagundi is the most appropriate choice for the given symptoms.

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: 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: A

Rationale: The correct answer is A: RA 8483. This law specifically established the Philippine Institute of Traditional and Alternative Health Care. RA 4823, RA 2483, and RA 3482 are incorrect as they do not pertain to the creation of this institute. RA 4823 is about the Agricultural Land Reform Code, RA 2483 is about the Philippine Medical Care Commission, and RA 3482 is about the Philippine Medical Association. Therefore, based on the specific content of each law, A is the correct choice for the creation of the Philippine Institute of Traditional and Alternative Health Care.

Correct Answer: D

Rationale: The correct answer is D because putting the baby to breast stimulates the release of oxytocin, which helps the uterus contract and reduce post-delivery blood loss. This promotes faster recovery for the mother. A: Incorrect - Lactation usually begins within 24-48 hours, not 1 to 3 days after delivery. B: Incorrect - Nipple stretching exercises are not necessary for breastfeeding success and can cause discomfort. C: Incorrect - Excessive washing of nipples can strip away natural oils and cause dryness or irritation, affecting breastfeeding.

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.
