Head nurses or nurse supervisors direct nursing activities. They plan work schedules and assign duties to nurses and aides, provide or arrange for training, and visit patients to observe nurses and to insure that care is proper. They may also insure records are maintained and equipment and supplies are ordered. 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 all States and the District of Columbia.
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. 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.
