In color-coded digital thermometers, what do blue and red indicate respectively?

• A. Blue: Rectal, Red: Oral
• B. Blue: Axillary, Red: Tympanic
• C. Blue: Tympanic, Red: Axillary
• D. Blue: Oral, Red: Rectal

Answer: (D)

Color cues on digital thermometers are used to guide placement and prevent cross-contamination. The standard convention is blue for oral use and red for rectal use. This makes it easy to tell at a glance which route the thermometer is intended for, and the tips are often color-coded accordingly. The blue-coded thermometer is placed under the tongue to measure oral temperature, while the red-coded one is designed for rectal insertion and used when a more core temperature reading is needed. Therefore, blue indicates oral and red indicates rectal. Other color pairings would not align with this common convention and could lead to confusion or unsafe placement.
