|A registered nurse’s (or RN’s) job description is simple; they work to promote patient health and to prevent illnesses. The RN works to educate both patients and the public about medical conditions, they treat patients and assist in rehabilitation, and provide advice to patients and their loved ones. An RN has to use their judgment in the services they provide.A lot of registered nurses are general nurses, who focus on patients’ total care. They give patients medication, under the supervision of a doctor, and they keep a record of patients’ progress and symptoms. RNs also supervise licensed practical nurses (LPNs), nursing assistants, and hospital orderlies.An RN can specialize in their work setting, or by the type of treatment they provide. For instance, critical-care nurses work in ICUs, and psych nurses treat mentally disordered patients. They can also specialize by condition; there are nurses that care only for those with AIDS or addiction issues.Nurses can also specialize in a certain organ; there are nurses just for patients with kidney disease and respiratory agents. An RN can specialize by population segment; there are nurses that provide care just for schoolchildren or elderly patients. RNs can also combine specialties; pediatric oncology and cardiac emergency nurses are in high demand.Some RNs elect to become advanced practical nurses, getting training above and beyond their RN schooling. They often work as primary practitioners, either with a physician or independently. Nurse-practitioners conduct physicals, diagnose and treat illnesses and injuries, provide shots, manage diabetes and hypertension, and order/interpret x-rays.
RNs practice in clinics and hospitals, often providing care in rural or inner-city areas that aren’t served by doctors; some even have private practices set up. An RN can prescribe medication, and in many areas they can practice without doctor supervision.
