What information should a technician record in the glucose monitor quality control record?

1. Date of last calibration

2. Model number of the monitor

3. Date of battery change

4. Last maintenance check

The correct answer is: Date of battery change

In the context of maintaining accurate glucose monitoring, recording the date of battery change is essential for ensuring device reliability and function. A glucose monitor can produce incorrect readings if the battery is low or depleted, which could lead to poor management of a patient’s diabetes or other health conditions. Documenting the date of battery change helps to establish a timeline for the monitor’s operational status and ensures that the technician is aware of when a new battery is required, which is critical for patient safety. Information such as the date of last calibration, model number of the monitor, and last maintenance check are also valuable for overall quality control but do not directly influence the immediate functionality of the glucose monitor as a battery change does. Regular monitoring and documentation of all these aspects contribute to optimal device performance, but the battery's status is a primary concern that affects the device's operational capability.
