Question 1

Which class of disinfectant is considered a high-level disinfectant (HLD) suitable for semi-critical items used in hyperbaric chambers?

Accepted Answer

Glutaraldehyde 2%

Answer

Glutaraldehyde 2% is an EPA-registered high-level disinfectant capable of killing all microorganisms except large numbers of bacterial spores, making it appropriate for semi-critical items.

Question 2

A hyperbaric patient has a known MRSA infection. What is the most appropriate isolation precaution level to implement during HBO therapy?

Accepted Answer

Contact precautions plus standard precautions

Answer

MRSA is transmitted primarily through direct or indirect contact, so contact precautions combined with standard precautions are required to prevent spread.

Question 3

What is the recommended minimum contact time for a sporicidal disinfectant to be effective on environmental surfaces in a hyperbaric unit?

Accepted Answer

As specified on the product label

Answer

Contact (wet) time specified on the product label must be followed to ensure the disinfectant achieves its stated efficacy against target organisms.

Question 4

Which of the following best describes the purpose of an infection control risk assessment (ICRA) in a hyperbaric facility?

Accepted Answer

Identify and mitigate risks of healthcare-associated infections during construction or renovation

Answer

An ICRA is a multidisciplinary risk assessment used to identify infection risks introduced by construction, renovation, or maintenance activities in healthcare settings.

Question 5

When cleaning a multiplace hyperbaric chamber after treating a patient with Clostridioides difficile (C. diff), which disinfectant is most appropriate?

Accepted Answer

Sodium hypochlorite (bleach) solution

Answer

C. difficile produces spores resistant to most disinfectants; EPA-registered sodium hypochlorite solutions are effective sporicidal agents for environmental decontamination.
