✍️ Sample CBET Questions & Answers

1. What does a 'risk-based PM program' use to prioritize maintenance frequency?
✓ Device criticality, failure consequences, and maintenance history

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 hospital laboratory centrifuge vibrates excessively during operation. The MOST likely cause is:
✓ An unbalanced load due to improperly paired or misplaced samples

Centrifuges must have balanced loads; unequal or improperly positioned samples create centrifugal force imbalance causing severe vibration.

3. What is the primary difference between a Class I and Class II medical device under FDA classification?
✓ Class I requires general controls only; Class II requires special controls such as performance standards

FDA Class I devices are subject to general controls only, while Class II devices require special controls (e.g., performance standards, post-market surveillance) to ensure safety and effectiveness.

4. A CT scanner's X-ray tube requires replacement. Which parameter most directly indicates tube wear?
✓ Total accumulated milliampere-seconds (mAs) / heat units

Accumulated heat units or mAs track the thermal stress on the anode; manufacturers define tube replacement thresholds based on this metric.

5. Which regulatory body classifies medical gas systems components as medical devices subject to 510(k) or PMA review?
✓ FDA

The FDA classifies medical gas equipment (regulators, flowmeters, outlets) as medical devices and requires 510(k) clearance or PMA approval before marketing.

6. What is the function of a network firewall between the medical device network and the hospital's general network?
✓ To control and filter network traffic based on security rules

A firewall controls and filters network traffic between segments based on security rules, protecting medical devices from unauthorized access.
