Registered Nurses (RNs) are licensed healthcare professionals who provide patient care, educate patients and the public about health conditions, and offer support to patients and their families. They work in a variety of settings, including hospitals, clinics, nursing homes, schools, and community health organizations. RNs assess patient health problems, administer treatments and medications, and collaborate with doctors and other healthcare staff to ensure the best possible outcomes for patients. To become an RN, individuals must complete an accredited nursing program and pass the NCLEX-RN licensing exam.
