Temperature taken at the armpit.

Rectal Temperature Oral Temperature Axillary Temperature Tympanic Temperature

Correct Answer:

Axillary Temperature

Explanation:

Axillary temperature is the reading taken in the armpit. This method is safe, noninvasive, and commonly used by CNAs when other routes aren’t practical (such as with children or residents who can’t cooperate or when the mouth or rectum isn’t accessible). It tends to be slightly less accurate than rectal or oral measurements because it reflects skin temperature influenced by the environment and sweating. For a reliable axillary reading, ensure the armpit is dry, place the thermometer in the center of the armpit, and keep the arm pressed snugly against the body for the full measurement time. Use this method consistently to track temperature trends over time.
