RECTAL USE:
Always use a probe cover when taking rectal measurements.
Commonly used for young children when it is difficult to take an oral or underarm temperature.
Lubricate with a water-soluble gel. Do not use petroleum jelly.
Gently insert the probe tip no more than 1.3 cm into the rectum. Do not force the tip into the
rectum if resistance is encountered.
Disinfect the thermometer after use.
