Which of the following is true about female health worker?
**Core Concept**
A female health worker is a vital part of the public health infrastructure, responsible for providing essential healthcare services to a defined population. These workers often operate at the grassroots level, focusing on community health education, maternal and child care, and disease prevention.
**Why the Correct Answer is Right**
The correct answer, **B. Covers a population of 5000 population**, is based on the World Health Organization's (WHO) definition of a female health worker's scope of practice. In many countries, female health workers are assigned to serve a population of approximately 5,000, providing doorstep healthcare services, conducting health check-ups, and offering guidance on nutrition, hygiene, and family planning. This targeted approach enables them to effectively address the unique health needs of their assigned population.
**Why Each Wrong Option is Incorrect**
**Option A:** Female health workers may operate at various levels, including sub-centre, primary health centre (PHC), and community health centre (CHC) levels, but acting solely at the PHC level is not a defining characteristic.
**Option C:** Chlorination of water sources is a critical public health intervention, but it is not a primary responsibility of a female health worker. This task is often carried out by water and sanitation teams or community health workers.
**Option D:** While postnatal visits are an essential part of maternal healthcare, the frequency of these visits can vary depending on the country's healthcare guidelines and protocols. A minimum of three postnatal visits is not a universally applicable standard.
**Clinical Pearl / High-Yield Fact**
Female health workers often serve as a vital link between the community and the healthcare system, providing essential services and promoting health education. Their role is crucial in achieving the United Nations' Sustainable Development Goals (SDGs), particularly SDG 3 (Good Health and Well-being).
**✓ Correct Answer: B. Covers a population of 5000 population**
