RPSGT Risk Management & Assessment 4

Question 1

Which of the following scenarios represents the greatest infection control risk in a sleep laboratory?

Accepted Answer

Reusing a single-patient-use disposable nasal cannula on multiple patients after only wiping it down with alcohol

Answer

Single-use disposable items must never be reused as they cannot be adequately sterilized and pose a significant cross-contamination and infection risk.

Question 2

A patient with a known history of claustrophobia is scheduled for CPAP titration. What is the MOST proactive risk management approach?

Accepted Answer

Inform the technologist in advance, desensitize the patient to the mask before lights-out, and have an alternative interface available

Answer

Proactive desensitization and having alternative mask options ready minimizes the risk of mask intolerance and study failure in claustrophobic patients.

Question 3

During a PSG study, the EEG suddenly shows a dramatic change in waveform morphology across all channels simultaneously. What is the most likely cause and the FIRST action to take?

Accepted Answer

Electrode artifact or a technical failure; check electrode impedances and connections

Answer

Simultaneous changes across all channels are almost always a technical artifact or equipment failure rather than a physiologic event, and should be verified technically first.

Question 4

A sleep lab is evaluating a new brand of electrode gel. What risk management step should occur BEFORE using the new gel on patients?

Accepted Answer

Verify the product is FDA-cleared or approved for its intended use and review its safety data sheet (SDS)

Answer

All products applied to patients must be FDA-cleared for their intended use, and their SDS reviewed for allergen or hazard information before clinical use.

Question 5

What is the primary purpose of having a written emergency response protocol posted in the sleep laboratory?

Accepted Answer

To ensure all staff respond consistently and correctly during a crisis, minimizing harm

Answer

Written protocols ensure standardized, rapid, and correct responses during emergencies when stress may impair improvised decision-making.
