CBET Preventive Maintenance and Calibration

Question 1

Which document typically defines the required PM interval for a medical device in a US hospital?

Accepted Answer

Manufacturer's service manual

Answer

The manufacturer's service manual specifies recommended PM intervals and procedures that biomed departments use to build their maintenance schedules.

Question 2

What is the primary purpose of calibrating a clinical thermometer used in patient care?

Accepted Answer

To verify its accuracy against a known reference standard

Answer

Calibration compares the device's output to a traceable reference standard to confirm accuracy within acceptable tolerances.

Question 3

Which organization publishes ANSI/AAMI standards relevant to biomedical equipment maintenance in the US?

Accepted Answer

Association for the Advancement of Medical Instrumentation (AAMI)

Answer

AAMI publishes consensus standards and technical information reports widely used by biomedical engineers for equipment maintenance and safety.

Question 4

A BMET is performing a PM on an infusion pump. Which test is most critical for patient safety?

Accepted Answer

Flow rate accuracy test

Answer

Flow rate accuracy directly affects drug dosing; an out-of-tolerance pump can deliver under- or over-doses with life-threatening consequences.

Question 5

What does 'equipment management inventory' primarily track in a biomed program?

Accepted Answer

Every device's location, PM schedule, and service history

Answer

A complete inventory ties each device to its asset number, location, PM due date, and maintenance history to ensure no device is missed.
