Registered Nurses (RNs) are healthcare professionals who provide patient care, educate patients and the public about health conditions, and offer emotional support to patients and their families. They work in a variety of settings, including hospitals, clinics, nursing homes, and schools. RNs are responsible for administering medications, monitoring patient health, collaborating with doctors, and assisting in medical procedures. To become an RN, individuals must complete an accredited nursing program and pass the NCLEX-RN licensing exam.
