Which of the following diseases is prevented by administration of the Hepatitis B vaccine?
- A. Jaundice
- B. Liver cancer
- C. Pneumonia
- D. Tuberculosis
Correct Answer: B
Rationale: The correct answer is B: Liver cancer. The Hepatitis B vaccine prevents Hepatitis B infection, which is a major cause of chronic liver disease and can lead to liver cancer. Jaundice (choice A) is a symptom of Hepatitis B infection, not a disease prevented by the vaccine. Pneumonia (choice C) and Tuberculosis (choice D) are both respiratory infections and are not prevented by the Hepatitis B vaccine. The key is to understand the specific disease targeted by the vaccine and its related health outcomes.

A woman, 6 months pregnant, came to the center for consultation. Which of the following substances is contraindicated?
- A. Tetanus toxoid
- B. Retinol 200,000 IU
- C. Ferrous sulfate 200mg
- D. Potassium iodate 200 mg capsule
Correct Answer: B
Rationale: The correct answer is B: Retinol 200,000 IU. Retinol in high doses can cause birth defects in a developing fetus. Pregnant women should avoid excessive vitamin A intake to prevent harm to the baby. Tetanus toxoid (A), ferrous sulfate (C), and potassium iodate (D) are safe and recommended for pregnant women to support their health and the baby's development. In summary, retinol 200,000 IU is contraindicated due to the potential for birth defects, while the other choices are safe and beneficial during pregnancy.
To monitor clients registered in long-term regimens, such as Multi-Drug Therapy, which component will be most useful?
- A. Tally report
- B. Output report
- C. Target/client list
- D. Individual health record
Correct Answer: C
Rationale: Step 1: Target/client list is most useful as it provides a comprehensive list of clients in long-term regimens.
Step 2: It allows for easy monitoring of individual progress and adherence to treatment plans.
Step 3: Tally report (A) only provides a count, lacking specific client information.
Step 4: Output report (B) may not include all necessary client details.
Step 5: Individual health record (D) is specific to one client, not ideal for overall monitoring.
Which numerator is used in computing the general fertility rate?
- A. Estimated midyear population
- B. Number of registered live births
- C. Number of pregnancies in the year
- D. Number of females of reproductive age
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.
Which biological used in Expanded Program on Immunization (EPI) is stored in the freezer?
- A. DPT
- B. OPV
- C. Hepatitis B vaccine
- D. Measles vaccine
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.
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?
- A. 99.06:100
- B. 100.94:100
- C. 50.23%
- D. 49.76%
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.
