    The physicians in a hospital form the center of medical staff. But they could not

provide effective medical care to their patients without the help of numerous other

medical employees. From the viewpoint of the patients, the nursing staff is particularly

important. Nurses are usually in close contact with patients as long as they are in the

hospital.

    A nurse does not study for as many years as a doctor. however , each must be equally

dedicated. Caring for sick persons requires a great deal of patience and concern. Most

nurses work long days, and they often must work at odd hours or during the night.

    Under the supervision (监管) of the head nurse, the nursing staff must provide nursing

services on a 24-hour basis and attend to patients' needs. This responsibility continues

around the clock, and so nurses must work in shifts. A shift is a period of duty, usually

eight in length. The nurses on the ward rotate their shifts. Some take turns working night

duty; others work odd shifts.

    A nurse must always be alert. She can never afford to be careless. This is true in all

nursing situation, but it is especially true in the intensive care unit. Patients under

intensive care are critically ill, and they must be monitored at all times. The nurses who

do intensive care duty have one of the most demanding jobs in the hospital.

    Serving as a nurse can be a very rewarding job. But it is not an easy one. Not every

person is suited to become a nurse. Only very dedicated people have chosen nursing as a

profession.
