Home Care of the Sick - Body temperature

A fever thermometer, available at any drugstore, is specially shaped to help the home nurse read any tiny change in the patient's temperature, such changes being measured in tenths of a degree. Instead of being round in cross-section like an ordinary thermometer, a fever thermometer is flat on one side and ridge-shaped on the other. The inner surface of the flat side is coated with a reflective material and the ridge-shaped side actually is a magnifying lens. Thus, to read a fever thermometer quickly and properly, one looks at the lens (ridged) side.
