Colorado CNA Practice Exam

Which method of taking temperature is considered to be the most accurate?

1. Axillary

2. Oral

3. Rectal

4. Temporal

The correct answer is: Axillary

Axillary temperature is considered to be the most accurate method because it is taken in the armpit, which is a more stable and consistent location than the mouth, rectum, or forehead. Oral temperature can be affected by recent food or drink consumption, and rectal temperature can be affected by recent bowel movements. Temporal temperature can be influenced by external factors such as sweating or drafts. Therefore, axillary temperature provides a more reliable measurement of core body temperature.
