At the advanced level, nurse practitioners provide basic primary health care. They diagnose and treat common acute illnesses and injuries. Nurse practitioners can prescribe medications in most States. Other advanced practice nurses include clinical nurse specialists, certified registered nurse anesthetists and certified nurse-midwives. Advanced practice nurses have met higher educational and clinical practice requirements beyond the basic nursing education and licensing required of all R.N.'s.
Most nurses work in well-lighted, comfortable health care facilities.
Home health and public health nurses travel to patients' homes and to schools, community centers and other sites. Nurses may spend considerable time walking and standing. They need emotional stability to cope with human suffering, emergencies and other stresses. Because patients in hospitals and nursing homes require 24-hour care, nurses in these institutions may work nights, weekends and holidays. They may also be on-call.
