Question 1

Which federal agency requires employers, including hyperbaric facilities, to have an Exposure Control Plan under the Bloodborne Pathogens Standard?

Accepted Answer

OSHA

Answer

OSHA's Bloodborne Pathogens Standard (29 CFR 1910.1030) requires all employers with potential occupational exposure to bloodborne pathogens to develop and implement a written Exposure Control Plan.

Question 2

A reusable transcutaneous oxygen (TCOM) probe cover is visibly contaminated with wound exudate. After cleaning, what level of reprocessing is minimally required before reuse on another patient?

Accepted Answer

High-level disinfection

Answer

Probe covers that contact mucous membranes or non-intact skin are semi-critical items requiring high-level disinfection before reuse on a different patient.

Question 3

What is the rationale for maintaining positive pressure ventilation in the hyperbaric unit anteroom rather than the treatment area itself?

Accepted Answer

Reduce airborne pathogen migration from common areas into the treatment space

Answer

Positive pressure in the anteroom relative to adjacent hallways prevents airborne contaminants from migrating into the treatment area where immunocompromised patients are cared for.

Question 4

A hyperbaric unit is planning to treat a patient with an extensively drug-resistant (XDR) organism. Which additional measure beyond standard contact precautions is MOST important to implement?

Accepted Answer

Dedicated single-use equipment and enhanced environmental cleaning frequency

Answer

XDR organisms require dedicated single-use equipment when possible and more frequent enhanced cleaning to prevent environmental persistence and cross-transmission.

Question 5

How should a hyperbaric technologist handle linen (sheets, gowns) removed from the chamber after treating a patient with an active wound infection?

Accepted Answer

Bag at point of use in a labeled leak-proof bag before transport

Answer

Contaminated linen must be bagged at the point of use in a leak-proof bag to contain pathogens and protect transport staff from exposure during handling.
