✍️ Sample CBET Questions & Answers
1. What does a 'risk-based PM program' use to prioritize maintenance frequency?
Risk-based programs assign higher PM priority to life-sustaining or high-risk devices and extend intervals for low-risk equipment with good histories.
2. A CT scanner's X-ray tube requires replacement. Which parameter most directly indicates tube wear?
Accumulated heat units or mAs track the thermal stress on the anode; manufacturers define tube replacement thresholds based on this metric.
3. What is the function of a network firewall between the medical device network and the hospital's general network?
A firewall controls and filters network traffic between segments based on security rules, protecting medical devices from unauthorized access.
4. A flash sterilization cycle (immediate-use steam sterilization) at 132°C in a pre-vacuum sterilizer requires a minimum exposure time of:
AAMI ST79 specifies a minimum of 4 minutes at 132°C for immediate-use steam sterilization (flash sterilization) in a pre-vacuum sterilizer with lumened devices.
5. A patient reports receiving a mild tingling sensation when touching the bed rail while connected to a patient monitor. No alarm has triggered. What is the appropriate immediate action?
A tingling sensation indicates stray electrical current flowing through the patient, which is a potentially dangerous leakage current situation.
6. A BMET is performing a PM on an infusion pump. Which test is most critical for patient safety?
Flow rate accuracy directly affects drug dosing; an out-of-tolerance pump can deliver under- or over-doses with life-threatening consequences.
