How often should the temperature of the medical office refrigerator be checked?

• A. Weekly
• B. Daily
• C. Monthly
• D. Only when opened

Answer: (B)

Regular monitoring of refrigerator temperature is essential because the effectiveness and safety of stored vaccines and medications depend on keeping the unit within a defined range. In a medical office, temperatures can drift due to door openings, power outages, or equipment issues. Checking the temperature every day allows you to detect any excursions quickly, document trends, and take prompt corrective actions to protect stored items and stay compliant with regulations.

Best practice is to record the current temperature at a consistent time each day (and use a thermometer with a min/max indicator or a data logger). If the reading is out of range, follow your facility’s protocol: identify the cause (door left open, thermostat issue, power problem), adjust as needed, move affected items to a safe unit if available, quarantine items if necessary, and arrange service or escalation. Temporary or infrequent checks—weekly, monthly, or only when the door is opened—may miss excursions and put stored materials at risk.
