(2) Numerical scale display. A numerical scale display looks much like the

temperature scale of a glass thermometer. A permanent temperature scale is displayed

and the patient's temperature is represented by a line. The longer the line is, the higher

the temperature reading.

a. **Digital Display. **On a digital display, the patient's temperature that is shown

is already rounded off to the nearest two-tenths of a degree Fahrenheit or to the nearest

one-tenth of a degree Celsius.

b. **Numerical Scale Display. **A numerical scale display is read using the same

procedures as a glass thermometer. Since you want your reading to be to the nearest

two-tenths of a degree Fahrenheit or to the nearest one-tenth of a degree Celsius, you

first determine which scale to use. Then find the mark on that scale that is nearest the

end of the displayed line. Once the mark had been identified, determine the

temperature represented by that mark on the scale.

There are three principal locations for taking the patient's temperature

(figure 2-4).
