CBET Preventive Maintenance and Calibration 3

Question 1

A BMET discovers a device failed its PM electrical safety test. What is the correct course of action?

Accepted Answer

Remove the device from service and tag it out until repaired

Answer

A failed safety test means the device poses a risk; removing and tagging it out prevents use until the fault is corrected and re-tested.

Question 2

What information is typically recorded in a PM completion report?

Accepted Answer

Date, technician ID, tests performed, results, and any parts replaced

Answer

PM documentation creates an auditable service record demonstrating the device was inspected, tested, and found safe on a specific date.

Question 3

Which tool is used to measure ground wire resistance during electrical safety testing?

Accepted Answer

Electrical safety analyzer

Answer

An electrical safety analyzer (such as a Fluke or Rigel unit) measures ground resistance, leakage currents, and line voltage in one instrument.

Question 4

What does a 'risk-based PM program' use to prioritize maintenance frequency?

Accepted Answer

Device criticality, failure consequences, and maintenance history

Answer

Risk-based programs assign higher PM priority to life-sustaining or high-risk devices and extend intervals for low-risk equipment with good histories.

Question 5

A pulse oximeter reads 94% SpO2 but a co-oximeter blood gas shows 99%. What is the most likely cause?

Accepted Answer

The SpO2 probe needs cleaning or replacement

Answer

A dirty or damaged probe causes inaccurate SpO2 readings; cleaning or replacing the probe is the first corrective step before further investigation.
