About Registered Nurses

Registered Nurses provide direct patient care, coordinate treatment plans, administer medications, and serve as the primary point of contact between patients and the broader healthcare team. They work in hospitals, outpatient clinics, long-term care facilities, home health agencies, and public health departments. RNs assess patient conditions by collecting health histories, performing physical examinations, and analyzing diagnostic results. They develop and implement care plans in collaboration with physicians, specialists, and allied health professionals. Administering medications accurately—including through IV lines, injections, and oral delivery—and monitoring patients for adverse reactions is a central daily responsibility. RNs educate patients and families about diagnoses, medications, and discharge instructions, making health literacy a key communication skill. In specialized settings such as the ICU, emergency department, or labor and delivery, RNs manage critically ill patients under protocols that require rapid clinical judgment. The profession requires emotional resilience, physical stamina, and the ability to function effectively under pressure. RNs are licensed by state boards of nursing after completing an Associate Degree in Nursing (ADN) or Bachelor of Science in Nursing (BSN) and passing the NCLEX-RN examination.
