CHS Infection Control & Prevention 3

Question 1

In a hyperbaric oxygen unit, which patient population is at HIGHEST risk for developing a healthcare-associated infection (HAI)?

Accepted Answer

Immunocompromised patients with chronic wounds

Answer

Immunocompromised patients with chronic wounds have impaired host defenses and open skin barriers, significantly elevating their risk for HAIs in any healthcare setting.

Question 2

What is the Spaulding classification category for a hyperbaric hood or mask that contacts intact mucous membranes?

Accepted Answer

Semi-critical

Answer

Items contacting mucous membranes are classified as semi-critical under Spaulding's scheme and require at minimum high-level disinfection between patient uses.

Question 3

A hyperbaric technologist notices a patient's wound dressing has become saturated with exudate mid-treatment inside the monoplace chamber. What is the priority infection control action upon chamber decompression?

Accepted Answer

Change the dressing immediately using aseptic technique and then decontaminate the chamber

Answer

Saturated dressings increase infection risk; the dressing should be changed immediately using aseptic technique, followed by thorough chamber decontamination to prevent cross-contamination.

Question 4

Which action is the SINGLE most effective measure to prevent the spread of healthcare-associated infections in a hyperbaric unit?

Accepted Answer

Consistent and proper hand hygiene

Answer

The CDC and WHO consistently identify hand hygiene as the single most effective intervention for preventing transmission of healthcare-associated pathogens.

Question 5

Biofilm formation inside hyperbaric chambers is most commonly associated with which surface or component?

Accepted Answer

Water reservoirs and humidification systems

Answer

Water reservoirs and humidification components provide a moist environment ideal for biofilm formation by organisms such as Pseudomonas aeruginosa and Legionella.
