Overview
In the early years of the Vietnam War, when resources were in short supply, nurses improvised in the field to provide care to the sick and wounded under extremely adverse conditions. This "field expediency" was the result of nursing knowledge as well as flexibility, creativity, audacity, and pragmatism. Nurses in other settings-for example, those practicing in remote areas, in developing nations, or during natural disasters-may also find themselves facing severe shortages or too few essential supplies or a lack of equipment. Familiarity with the methods associated with field expediency will help nurses adapt quickly-on the battlefield and off.
