Which of the following is classified as a 'high-level disinfection' process?

Accepted Answer

Soaking flexible endoscopes in glutaraldehyde

High-level disinfection with glutaraldehyde kills all microorganisms except high numbers of bacterial spores and is used for semi-critical items like endoscopes.

Question 3

A patient is placed on airborne precautions. The room should have which air-handling characteristic?

Accepted Answer

Negative pressure with at least 6-12 air exchanges per hour

Airborne infection isolation rooms require negative pressure with 6-12 air changes per hour to prevent pathogen spread to hallways.

Question 4

Which situation requires the use of an N95 respirator rather than a standard surgical mask?

Accepted Answer

Entering the room of a patient with varicella

Answer

Varicella (chickenpox) spreads via airborne droplet nuclei, requiring an N95 respirator for adequate protection.
