Book excerpt: A clear informative picture book for pre-schoolers, about the nurse and how to treat sick or old people. Nurses often work in hospitals. They look after sick people or patients. They take their temperature and blood pressure. Or they bring their medicine and check if they are fine. Nurses also talk to doctors to know how to treat each patient. But nurses can do other things too: assist at surgery, take care of the elderly in old people's homes or visit patients at their homes.
