Which precaution is essential when taking an axillary temperature?

• A. Observe the axillary area for dryness
• B. Place the thermometer under the patient’s chin
• C. Have the patient hold their breath during measurement
• D. Dip the probe in water before use

Answer: (B)

Accuracy in axillary temperature relies on proper placement and dry contact with the armpit. The underarm should be dry so the thermometer can sit against the skin and give a true reading without moisture distorting it. After placing the tip in the center of the axilla, keep the arm pressed against the body for the full measurement time to maintain consistent contact. Placing the thermometer under the chin would measure a different site (oral/temporal), and actions like holding the breath or dipping the probe in water don’t help with the accuracy of an axillary reading.
