Which temperature site is NOT listed among the standard sites?

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

Answer: (A)

Measuring body temperature at standard sites centers on reliability and consistency for quick clinical decisions. Traditionally, the routine sites are oral, rectal, and axillary, with tympanic measurements also commonly used in many settings. Forehead temperature, usually taken with infrared devices, isn’t considered a standard site because readings there can be highly affected by the environment—room temperature, airflow, and sweating—along with variations in skin perfusion and device placement. These factors can produce less accurate or less reproducible results compared to the standard sites. Some newer technologies assess temperature in the forehead/temporal area, but they’re often treated as a separate method rather than a traditional standard site. That’s why forehead measurement is not listed among the standard sites.
