GAMSAT Safety and Infection Control 3

Question 1

A ward experiences a cluster of Clostridioides difficile (C. diff) infections. Which hand hygiene agent is most effective against C. diff spores?

Accepted Answer

Soap and water with friction

Answer

C. diff produces spores resistant to alcohol; soap and water with friction physically removes spores from hands.

Question 2

During a surgical procedure, the scrub nurse accidentally touches an unsterile surface with a gloved hand. What is the correct response?

Accepted Answer

Immediately change gloves and the contaminated instrument

Answer

Any break in sterile technique requires immediate correction by changing gloves and replacing any contaminated instruments.

Question 3

Which of the following isolation room requirements is specific to airborne precautions?

Accepted Answer

Negative pressure ventilation with at least 12 air changes per hour

Answer

Airborne isolation requires negative pressure rooms with high air-change rates to prevent infectious particles from escaping into the corridor.

Question 4

A healthcare facility implements a bundle approach to prevent central-line-associated bloodstream infections (CLABSI). Which element is NOT part of the standard CLABSI prevention bundle?

Accepted Answer

Routine line replacement every 72 hours

Answer

Routine scheduled line replacement is not evidence-based and is not part of the CLABSI bundle; lines should be removed when no longer needed.

Question 5

What is the primary risk associated with reusing single-use medical devices (SUDs) without reprocessing?

Accepted Answer

Residual protein contamination leading to infection transmission

Answer

SUDs may retain protein deposits after use that are difficult to remove, creating a risk of transmitting prions and other pathogens.
