SGNA Infection Control and Safety 2

Question 1

Standard precautions in the GI endoscopy unit apply to which patients?

Accepted Answer

All patients regardless of known infection status

Answer

Standard precautions treat all blood, body fluids, and mucous membranes as potentially infectious, protecting both patients and healthcare workers universally.

Question 2

What is the proper technique for removing contaminated gloves to prevent self-contamination?

Accepted Answer

Peel off inside-out using clean technique

Answer

Gloves should be removed by peeling inside-out, keeping contaminated surfaces turned inward so clean hands never contact the soiled exterior.

Question 3

According to the Spaulding Classification, flexible GI endoscopes are categorized as which level?

Accepted Answer

Semi-critical

Answer

Semi-critical items contact mucous membranes but do not penetrate sterile tissue; they require high-level disinfection at minimum (sterilization preferred when possible).

Question 4

What action should be taken immediately after an endoscope is used at the point of care (bedside)?

Accepted Answer

Wipe external surfaces and flush channels with enzymatic detergent

Answer

Immediate post-procedure bedside cleaning prevents biofilm formation by wiping outer surfaces and flushing channels with enzymatic detergent before transport.

Question 5

Which disinfectant concentration test should be performed before each use of high-level disinfectant (HLD) solution?

Accepted Answer

Minimum effective concentration (MEC) test strips

Answer

MEC test strips verify that the disinfectant remains above the minimum effective concentration; diluted or expired solution will not achieve high-level disinfection.
