Which temperature site is used to measure a rectal temperature?

• A. Oral
• B. Rectal
• C. Tympanic
• D. Axillary

Answer: (D)

Rectal temperature is measured at the rectum, using a lubricated probe inserted gently into the anus. This site provides the most accurate reflection of core body temperature and is often used when precision is essential or when other routes are unreliable, such as with infants, uncooperative patients, or certain medical conditions. The other common sites—oral (mouth), tympanic (ear), and axillary (armpit)—offer easier and less invasive readings but can be influenced by recent intake, breathing, or ambient temperature, making them less consistent in some situations.
