Where should a digital thermometer be placed when measuring temperature?

• A. In the designated site (oral, underarm, or as policy allows)
• B. In the ear canal only
• C. In the rectum only
• D. In the mouth with the cap left off

Answer: (A)

Taking a digital temperature means placing it at the site that the facility policy and the resident’s condition designate. This could be oral, under the arm (axillary), or rectal—the approved site for that person and situation. Following the designated site ensures readings are accurate and comparable over time, which is essential for spotting fevers or trends.

The specific site may vary, and some settings may use ear readings in certain cases, but only when policy allows and the device is used correctly. Always use a clean probe cover or cap with the thermometer; leaving the cap off can contaminate the device and lead to inaccurate results. In short, place the thermometer at the site approved by policy and the resident’s needs, and adhere to hygiene guidelines.
