Registered Nurses (RNs) are licensed medical professionals who provide hands-on care in various medical and community settings. They perform a range of duties and work directly with patients, doctors, and other healthcare professionals. Here are some of the tasks that RNs typically perform:

• Assess patients conditions
• Record patients medical histories and symptoms
• Observe patients and record observations
• Administer treatments and medications
• Educate individuals and the community about health conditions
• Offer valuable advice and emotional support to patients and their families
• Manage care
• Control safety and infection
• Promote and maintain health
• Provide basic care and comfort

RNs work in various healthcare settings, including hospitals, physicians offices, nursing homes, schools, and home healthcare services. They can also specialize in different areas, such as emergency room nursing, intensive care unit nursing, and medical-surgical nursing.

To become an RN, one must complete an approved nursing program, which can be a bachelors degree in nursing, an associates degree in nursing, or a diploma from an approved nursing program. After completing the program, one must pass the National Council Licensure Examination for Registered Nurses (NCLEX-RN) to become licensed.

Overall, RNs play a crucial role in providing and coordinating patient care, and their responsibilities vary depending on the department and position they work in.
