BTC Medical Equipment Maintenance 3

Question 1

A patient monitor alarm is not activating at the set threshold. After ruling out software settings, what is the next likely cause to investigate?

Accepted Answer

Sensor or transducer calibration drift

Answer

Calibration drift in sensors or transducers can cause measured values to deviate from true physiological values, preventing alarm activation.

Question 2

Which document should a biomedical technician consult FIRST when servicing unfamiliar medical equipment?

Accepted Answer

The manufacturer's service manual

Answer

The manufacturer's service manual contains device-specific procedures, tolerances, and safety warnings essential for safe and accurate maintenance.

Question 3

An electrosurgical unit (ESU) is producing inconsistent cutting power. Which component is MOST likely to cause this issue?

Accepted Answer

The RF output power supply or its regulating circuit

Answer

Inconsistent cutting power typically points to a fault in the RF generator's power supply or regulation circuitry that controls output.

Question 4

What is the primary purpose of a CMMS (Computerized Maintenance Management System) in a biomedical department?

Accepted Answer

Tracking equipment inventory, PM schedules, and work orders

Answer

A CMMS centralizes equipment records, PM schedules, work order history, and compliance documentation for the biomedical department.

Question 5

During PM on a pulse oximeter, the SpO2 reading at a simulated 98% saturation shows 94%. The BEST next step is to:

Accepted Answer

Check and clean the probe, then retest before recalibrating

Answer

A dirty or damaged probe is a common cause of inaccurate SpO2 readings; cleaning and retesting is the appropriate first step.
