Question 1

Which level of disinfection is required for semi-critical instruments that contact mucous membranes but do not penetrate tissue?

Accepted Answer

High-level disinfection

Answer

Semi-critical items such as vaginal specula and endoscopes contact mucous membranes and require high-level disinfection to eliminate all microorganisms except bacterial spores.

Question 2

The purpose of an autoclave's biological indicator (spore test) is to:

Accepted Answer

Confirm that sterilization conditions were sufficient to kill the most resistant organisms

Answer

Biological indicators contain Geobacillus stearothermophilus spores; if they are killed, it confirms the autoclave achieved true sterilization.

Question 3

When removing PPE after patient care, which item is removed LAST?

Accepted Answer

Mask or respirator

Answer

The CDC's recommended doffing sequence removes the mask/respirator last because it protects the respiratory tract from airborne contamination during doffing.

Question 4

MRSA requires which transmission-based precaution?

Accepted Answer

Answer

MRSA spreads primarily through direct and indirect contact with colonized skin or contaminated surfaces, requiring contact precautions.

Question 5

An accidental needlestick injury should be managed FIRST by:
