CBIC Infection Prevention 3

Question 1

A hospital experiences a cluster of Legionnaires' disease cases. The FIRST priority investigation step is to:

Accepted Answer

Conduct a water system risk assessment and collect environmental samples

Answer

The immediate priority is to identify and characterize the environmental source through a water system risk assessment and sampling to guide targeted remediation.

Question 2

Which sterilization method is MOST appropriate for heat-sensitive flexible endoscopes?

Accepted Answer

High-level disinfection with glutaraldehyde or OPA

Answer

Flexible endoscopes that contact mucous membranes are semicritical items requiring high-level disinfection; steam and dry heat would damage them.

Question 3

In the chain of infection, which link does respiratory hygiene/cough etiquette primarily interrupt?

Accepted Answer

Mode of transmission

Answer

Covering coughs and sneezes and disposing of tissues interrupts the mode of transmission by reducing respiratory droplet spread in the environment.

Question 4

Which metric is used by NHSN to adjust HAI rates for patient population risk and allow fair facility comparisons?

Accepted Answer

Standardized Infection Ratio (SIR)

Answer

The SIR compares observed infections to a risk-adjusted predicted number based on national baseline data, enabling meaningful benchmarking across facilities.

Question 5

A construction project is beginning adjacent to an oncology unit. The MOST critical infection prevention measure is to:

Accepted Answer

Move all immunocompromised patients to a different floor and establish an ICRA

Answer

Implementing an Infection Control Risk Assessment (ICRA) and relocating highly susceptible patients protects immunocompromised individuals from fungal spores released during construction.
