PAM Equipment Operation & Maintenance 3

Question 1

A clinician notices that a hydrocollator pack no longer retains heat for the standard 20-minute treatment. What is the MOST likely maintenance issue?

Accepted Answer

The water level in the hydrocollator is below the required fill line

Answer

When the water level falls below the heating element or pack level, heat transfer is compromised and packs fail to reach or maintain therapeutic temperature.

Question 2

For a therapeutic laser (low-level laser therapy) device, why must the clinician verify the equipment's wavelength specification before each new protocol?

Accepted Answer

Different wavelengths have different tissue penetration depths affecting clinical dosing

Answer

Wavelength directly determines how deeply photons penetrate tissue, so verifying wavelength ensures the correct dose reaches the intended target tissue depth.

Question 3

Which maintenance log entry is REQUIRED by most accreditation standards for electrical stimulation equipment?

Accepted Answer

Date of each use, any malfunctions noted, and dates of electrical safety inspections

Answer

Accreditation standards require that equipment logs document usage, reported malfunctions, and scheduled electrical safety inspections to ensure ongoing patient safety.

Question 4

When a cryotherapy unit (cold compression device) displays a temperature reading 10°F higher than the set point, the BEST corrective action is:

Accepted Answer

Tag the unit out of service and request biomedical engineering calibration

Answer

A temperature sensor reading that deviates significantly from the set point indicates a calibration fault requiring biomedical engineering inspection, not a clinical workaround.

Question 5

What is the correct procedure for storing self-adhesive electrodes after use to maximize their lifespan?

Accepted Answer

Return them to their original backing liner and store in a sealed bag at room temperature

Answer

Returning electrodes to their backing liner in a sealed bag prevents the adhesive from drying out, maintaining conductivity and reducing skin irritation on reuse.
