CHT Regulatory Standards & Infection Control 3

Question 1

A patient with an active Clostridioides difficile infection is scheduled for hyperbaric therapy. What is the MOST appropriate infection control measure?

Accepted Answer

Place patient last in schedule and use contact precautions with sporicidal disinfection

Answer

C. diff requires contact precautions; scheduling the patient last and using an EPA-registered sporicidal disinfectant on chamber surfaces limits environmental contamination.

Question 2

Which level of disinfection is required for hyperbaric chamber acrylic viewports that come into direct contact with patient secretions?

Accepted Answer

High-level disinfection

Answer

Items that contact mucous membranes or non-intact skin are semi-critical and require high-level disinfection per Spaulding classification.

Question 3

Under The Joint Commission standards, a root cause analysis (RCA) is triggered in a hyperbaric unit when:

Accepted Answer

A sentinel event such as a fire or unexpected patient death occurs

Answer

TJC defines sentinel events (e.g., patient death, serious harm, fire) as requiring a root cause analysis and corrective action plan.

Question 4

According to CDC Hand Hygiene Guidelines, alcohol-based hand rub is NOT preferred over soap and water in which hyperbaric-specific situation?

Accepted Answer

When hands are visibly soiled with blood or body fluids

Answer

CDC guidelines require soap and water (not alcohol rub) when hands are visibly soiled with blood, body fluids, or organic material.

Question 5

Which NFPA 99 requirement specifically governs the electrical grounding of equipment introduced into a Class A hyperbaric chamber?

Accepted Answer

Equipment must be approved for use in oxygen-enriched atmospheres and properly grounded to prevent static discharge

Answer

NFPA 99 requires that electrical equipment used in oxygen-enriched hyperbaric environments be approved for that atmosphere and grounded to prevent ignition from static discharge.
