How should thermometers be maintained?

• A. Calibrated yearly and sanitized after each use
• B. Calibrated regularly and sanitized after each use
• C. Not required to calibrate if digital
• D. Replaced daily

Answer: (B)

Regular calibration and sanitization after each use are essential for thermometer maintenance. Calibration keeps readings accurate because sensor performance can drift over time, so following manufacturer guidelines or facility policy for how often to check and recalibrate ensures the device still measures temperatures correctly. Sanitizing after every patient or user prevents cross-contamination; use an approved disinfectant and let it dry before storing. This applies to digital and non-digital thermometers alike, since accuracy checks matter even for digital sensors. Replacing the thermometer daily is unnecessary if it’s properly calibrated and cleaned.
