Certified Biomedical Equipment Technician (CBET) 2025 – 400 Free Practice Questions to Pass the Exam

The statement made by the nurse, "Nothing happens when I press the buttons," indicates that there is a lack of response from the syringe pump, suggesting that it may be in a locked state. Medical devices like syringe pumps often have features designed to prevent accidental changes to the settings, and these features include keypad locks that can be activated for safety reasons. This is particularly important in environments such as hospitals where medication delivery must be closely monitored and controlled.

When a keypad is locked, all functions that require button presses, including changing delivery settings, are disabled. This ensures that the settings remain consistent and that medications are not inadvertently altered during administration. Therefore, the most logical reason for the nurse's inability to change the delivery setting is that the keypad lock feature has been engaged to avoid tampering or unauthorized changes.

Understanding this functionality is crucial for biomedical equipment technicians, as they need to be familiar with the operation and safety features of the devices they service. Recognizing a locked keypad as a potential issue allows them to assist healthcare providers efficiently and ensure proper operation of the equipment.
