Correct answer: A. The resident just drank a cup of hot coffee.
Consuming hot or cold beverages, or smoking, can temporarily alter oral temperature readings. It's crucial to wait 15-20 minutes after these activities before taking an oral temperature to ensure accuracy.
Why the other options are wrong
- B. Anticoagulant medication does not contraindicate oral temperature measurement.
- C. Hypertension does not directly contraindicate oral temperature measurement.
- D. Mild arthritis in the hands does not affect the ability to take an oral temperature.
