BRPT Infection Control and Safety Protocols 2

Question 1

EEG gold cup electrodes that are reused between patients should be processed using which minimum standard?

Accepted Answer

High-level disinfection or sterilization

Answer

Reusable EEG electrodes are semi-critical items that contact broken skin and require at minimum high-level disinfection or sterilization between patients.

Question 2

Glutaraldehyde (e.g., Cidex) used for high-level disinfection of sleep study equipment is considered hazardous because it:

Accepted Answer

Can cause respiratory irritation, skin sensitization, and mucous membrane damage

Answer

Glutaraldehyde vapors are toxic and can cause significant respiratory irritation, occupational asthma, and skin/mucous membrane sensitization, requiring proper ventilation and PPE.

Question 3

Which sterilization method is preferred for heat-sensitive sleep lab equipment such as CPAP circuit tubing?

Accepted Answer

Ethylene oxide (EtO) gas sterilization

Answer

Ethylene oxide gas sterilization operates at low temperatures and is preferred for heat-sensitive items like plastic CPAP circuit tubing.

Question 4

A patient arrives for a sleep study with an active MRSA wound infection. Which precautions should be implemented in addition to Standard Precautions?

Accepted Answer

Contact precautions

Answer

MRSA is transmitted by direct or indirect contact, so contact precautions (gown and gloves) must be added to Standard Precautions to prevent spread.

Question 5

After removing PPE following care of an isolation patient, in which order should items be removed to minimize self-contamination?

Accepted Answer

Gloves → gown → goggles/face shield → mask/respirator → hand hygiene

Answer

CDC recommends removing gloves first (most contaminated), then gown, then goggles/face shield, and finally the mask/respirator, with hand hygiene after removing gloves and again after all PPE is removed.
