There are several main types of nurses in India:

Registered Nurse (RN) - An RN is a nurse who has completed a diploma or degree program in nursing and passed the national nursing exam to obtain registration with the Indian Nursing Council. RNs provide general nursing care across healthcare settings.

Auxiliary Nurse Midwife (ANM) - ANMs receive 18 months of training and provide primary, maternal, and child healthcare, especially in rural areas.

Lady Health Visitor (LHV) - LHVs receive two years of training focused on community health. They provide care and health education, especially for women and children.

Nursing Assistant/Midwifery Assistant - These nurses receive 6-12 months of training and work under RNs or ANMs' supervision.

Specialist Nurses - These include nurses with additional qualifications and experience in critical care, operation theatre, neonatal care, etc.

Nurse Practitioners - NPs have advanced education (Master's or PhD) and can independently diagnose, treat, and prescribe medications. The NP role is still emerging in India.

In summary, the main types are RNs, ANMs, LHVs, nursing assistants, specialist nurses, and NPs, with training and scope of practice varying across these nurse designations. The Indian Nursing Council governs the nursing education system and regulations.
