Question 1 of 9

In immunization, which of the following measures is considered the most effective in controlling the occurrence of diseases?

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.

Question 2 of 9

What is the minimum interval between the administration of two doses of the MMR vaccine?

Correct Answer: B

Rationale: The correct answer is B (4 weeks) for the minimum interval between two doses of the MMR vaccine. This interval is necessary for the body to develop a strong immune response to the vaccine components. Waiting at least 4 weeks allows the immune system to properly process and respond to the initial dose before receiving the second dose. Administering the second dose too soon may result in a weaker immune response and decreased effectiveness of the vaccine. Choices A, C, and D are incorrect as they are not in line with the recommended minimum interval for effective vaccination.

Question 3 of 9

What is the best reason for administering vitamin A to a postpartum client?

Correct Answer: A

Rationale: The correct answer is A: To help strengthen her immune system. Vitamin A plays a crucial role in maintaining a healthy immune system, which is especially important for postpartum women to prevent infections. Vitamin A deficiency can weaken the immune response, making the body more susceptible to infections. Explanation for other choices: B: To improve her vision - While vitamin A is essential for good vision, it is not the primary reason for administering it to a postpartum client. C: To protect her from infection - This is partially correct, as vitamin A helps protect against infections, but the primary reason is to strengthen the immune system. D: To promote wound healing - Vitamin A is important for wound healing, but the immune system support is the key reason for administering it in the postpartum period.

Question 4 of 9

What is given to a child with measles?

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.

Question 5 of 9

In the census of the Philippines in 1995, there were about 35,299,000 males and about 34,968,000 females. What is the sex ratio?

Correct Answer: B

Rationale: The sex ratio is calculated by dividing the number of males by the number of females and multiplying by 100. In this case, (35,299,000 / 34,968,000) x 100 = 100.94:100. This means for every 100 females, there are 100.94 males, indicating a slightly higher number of males. Choice A (99.06:100) is incorrect as it suggests fewer males than females, which is not the case. Choice C (50.23%) and choice D (49.76%) are incorrect as they represent percentages rather than ratios, leading to a misleading interpretation of the data.

Question 6 of 9

Which of the following vaccines is recommended to be given at birth?

Correct Answer: A

Rationale: The correct answer is A: BCG. BCG vaccine is recommended at birth to prevent tuberculosis. It is given to protect infants from severe forms of TB. Other choices (B: Hepatitis B, C: OPV, D: Measles) are typically given at later stages as part of the routine childhood vaccination schedule. Hepatitis B vaccine is usually given within 24 hours of birth, OPV is given in multiple doses starting at 6 weeks of age, and Measles vaccine is given at around 12-15 months of age. Therefore, BCG is the recommended vaccine to be given at birth compared to the other choices.

Question 7 of 9

Which of the following health professionals can sign the birth certificate?

Correct Answer: D

Rationale: The correct answer is D because all of these health professionals can sign a birth certificate. Public health nurses, rural health midwives, and municipal health officers are all qualified to verify and certify births. This is important for accurate record-keeping and legal purposes. Each of these professionals has the training and authority to confirm the details of a birth and sign the necessary documentation. Therefore, the correct answer is D, as any of these health professionals can sign the birth certificate. The other choices (A, B, and C) are incorrect because they limit the scope of who can sign the birth certificate, whereas the correct answer encompasses all the options provided.

Question 8 of 9

Which biological used in Expanded Program on Immunization (EPI) is stored in the freezer?

Correct Answer: B

Rationale: The correct answer is B: OPV. The oral polio vaccine (OPV) used in the Expanded Program on Immunization (EPI) is stored in the freezer to maintain its potency. OPV is a live vaccine that requires cold storage to prevent the virus from becoming inactive. DPT, Hepatitis B vaccine, and Measles vaccine are typically stored in the refrigerator, not the freezer, as they are either killed or attenuated vaccines that remain stable at higher temperatures. Therefore, the need for freezer storage specifically points to OPV as the correct answer.

Question 9 of 9

In calculating the crude death rate of your municipality, with a total population of about 18,000 last year, there were 94 deaths. Among the deceased, 20 died due to heart diseases, and 32 were aged 50 years or older. What is the crude death rate?

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.
