As per IPHS norms, the proposed number of female health worker at sub-centre :

## **Core Concept**
The Indian Public Health Standards (IPHS) provide guidelines for infrastructure and staffing at various levels of healthcare in India. A sub-centre is the most peripheral and first contact point between the primary healthcare system and the community. It is staffed by two Auxiliary Nurse Midwives (ANMs), also known as female health workers.

## **Why the Correct Answer is Right**
As per IPHS norms, each sub-centre should have two Auxiliary Nurse Midwives (ANMs) or female health workers. These workers play a crucial role in delivering primary healthcare services, including maternal and child health services, family welfare services, and basic preventive and promotive healthcare. The presence of two ANMs at a sub-centre ensures 24/7 availability of skilled health personnel for attending to emergencies and providing routine care.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option suggests one female health worker, which is insufficient for a sub-centre as it does not ensure 24/7 coverage and adequate service delivery.
- **Option C:** This option suggests three female health workers, which exceeds the minimum IPHS norm for a standard sub-centre.
- **Option D:** This option also suggests a number that does not align with the standard IPHS recommendations.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the IPHS guidelines recommend two female health workers (ANMs) per sub-centre. This is crucial for ensuring adequate coverage and delivery of healthcare services. Remembering such specific norms can help in quickly eliminating incorrect options during exams.

## **Correct Answer:** B. 2.
