Question 1 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 2 of 9

Which numerator is used in computing the general fertility rate?

Correct Answer: B

Rationale: The correct answer is B: Number of registered live births. The general fertility rate is calculated by dividing the number of live births in a specific period by the total number of women of reproductive age during that period. This numerator reflects the actual occurrence of live births in the population, making it the most appropriate measure for determining fertility rates accurately. A: Estimated midyear population is not used as the numerator because it does not directly measure fertility rates. C: Number of pregnancies in the year includes all pregnancies, not just live births, which would overestimate the fertility rate. D: Number of females of reproductive age is not used as the numerator as it represents the total population, not the specific group giving birth.

Question 3 of 9

Civil registries are important sources of data. Which law requires registration of births within 30 days from the occurrence of the birth?

Correct Answer: A

Rationale: The correct answer is A: PD 651. This law is the Civil Registry Law, which mandates the registration of births within 30 days. PD 651 was enacted specifically to ensure the timely and accurate recording of vital events. Act 3573 pertains to the reporting of communicable diseases, not birth registration. RA 3753 focuses on the use of an alias or pseudonym, not birth registration. RA 3375 involves the registration of firearms, not births. Overall, PD 651 is the most relevant law in requiring the registration of births within 30 days, making it the correct choice.
