CABT Installation, Maintenance & Troubleshooting 5

Question 1

During preventive maintenance on a patient-controlled analgesia (PCA) pump, the technician discovers the drug library is outdated. What is the correct action?

Accepted Answer

Update the drug library per facility protocol and pharmacy approval before returning to service

Answer

An outdated drug library is a patient safety risk; it must be updated per facility protocol with pharmacy approval before the PCA pump is returned to clinical use.

Question 2

A biomedical technician suspects RF interference is affecting a telemetry monitoring system. Which action is most appropriate initially?

Accepted Answer

Identify and document the interference source and notify the clinical engineering and IT teams

Answer

The first step is to identify and document the RF interference source systematically and escalate to appropriate teams before taking corrective action.

Question 3

What is the significance of a 'risk score' assigned to a medical device in the equipment management program?

Accepted Answer

It determines the maintenance priority, frequency, and inclusion criteria for the device

Answer

A risk score based on function, physical risk, and maintenance requirements determines a device's maintenance priority, interval, and whether it is included in the management program.

Question 4

When calibrating a patient scale used for medication dosing, the biomedical technician should use calibration weights that are:

Accepted Answer

NIST-traceable certified calibration weights

Answer

Calibration must use NIST-traceable certified weights to ensure the calibration result is metrologically valid and legally defensible.

Question 5

A suction regulator used in the OR fails to maintain set vacuum pressure. After checking the wall vacuum supply and finding it adequate, the most likely internal cause is:

Accepted Answer

A worn diaphragm or damaged internal valve seat

Answer

With adequate wall vacuum supply, internal vacuum regulator failures are most commonly caused by a worn diaphragm or damaged valve seat that prevents proper pressure control.
