Nurses play several key roles in healthcare including educating patients, providing emotional support, and caring for patients. As a nurse, one educates patients about their conditions, treatments, and self-care. Emotional support of patients and their families is also important. Nurses directly care for patients by assessing health, administering treatments, and ensuring comfort and recovery. While nursing offers a rewarding career with opportunities to help others and learn, it also involves long hours, physically and mentally demanding work, and sometimes guilt over inability to help all patients.
