1. What is the purpose of a population pyramid?

Correct answer: B

Rationale: A population pyramid is a graphical illustration that shows the age and sex composition of a population. It displays the percentage or number of individuals in different age groups and gender categories. This tool helps in understanding the demographic structure of a population, including aspects such as birth rates, death rates, life expectancy, and dependency ratios.

2. If the RHU needs additional midwife items, to whom should you submit the request for approval?

Correct answer: D

Rationale: When the RHU requires additional midwife items, the request for approval should be submitted to the Municipal Health Board. According to R.A. 7160, basic health services have been decentralized from the national government to local government units, including municipalities. The Municipal Health Board plays a crucial role in overseeing health-related matters at the local level, making it the appropriate authority to seek approval for additional midwife items.

Correct answer: B

Rationale: Cyclical variation best describes the periodic fluctuation in the number of Dengue fever cases in the community, typically increasing towards the end of the rainy season and then decreasing during drier periods. This pattern suggests a recurring cycle rather than a sudden outbreak (epidemic), random occurrence (sporadic), or gradual long-term change (secular occurrence).

4. What is the recommended duration of exclusive breastfeeding?

Correct answer: B

Rationale: The World Health Organization recommends exclusive breastfeeding for the first 6 months of a child's life. During this time, breast milk provides all the necessary nutrients for the baby's growth and development, offering protection against infections and supporting optimal health outcomes. After 6 months, complementary foods can be introduced while continuing breastfeeding up to 2 years of age or beyond.
