As the largest health care occupation, registered nurses held about 2.5 million jobs in 2006. Hospitals employed the majority of RNs, with 59 percent of jobs. Other industries also employed large shares of workers. About 8 percent of jobs were in offices of physicians, 5 percent in home health care services, 5 percent in nursing care facilities, 4 percent in employment services, and 3 percent in outpatient care centers. The remainder worked mostly in government agencies, social assistance agencies, and educational services. About 21 percent of RNs worked part time.

Most RNs work in well-lighted, comfortable health care facilities. Home health and public health nurses travel to patients’ homes, schools, community centers, and other sites. RNs may spend considerable time walking, bending, stretching, and standing. Patients in hospitals and nursing care facilities require 24-hour care; consequently, nurses in these institutions may work nights, weekends, and holidays. RNs also may be on call—available to work on short notice. Nurses who work in offices, schools, and other settings that do not provide 24-hour care are more likely to work regular business hours. About 21 percent of RNs worked part time in 2006, and 7 percent held more than one job.

Nursing has its hazards, especially in hospitals, nursing care facilities, and clinics, where nurses may be in close contact with individuals who have infectious diseases and with toxic, harmful, or potentially hazardous compounds, solutions, and medications. RNs must observe rigid, standardized guidelines to guard against disease and other dangers, such as those posed by radiation, accidental needle sticks, chemicals used to sterilize instruments, and anesthetics. In addition, they are vulnerable to back injury when moving patients, shocks from electrical equipment, and hazards posed by compressed gases. RNs also may suffer emotional strain from caring for patients suffering unrelieved intense pain, close personal contact with patients’ families, the need to make critical decisions, and ethical dilemmas and concerns.
