Question 1

When performing a hand hygiene compliance audit, an infection preventionist observes that a nurse applies alcohol-based hand rub but does not cover all surfaces of both hands. This represents which type of hand hygiene failure?

Accepted Answer

Technique failure

Answer

A technique failure occurs when hand hygiene is performed at the correct indication but with improper technique, such as insufficient coverage of all hand surfaces.

Question 2

Which of the following is the RECOMMENDED antiseptic for skin preparation prior to inserting a central venous catheter?

Accepted Answer

Chlorhexidine gluconate >0.5% in alcohol

Answer

Current evidence and NHSN/APIC guidelines support chlorhexidine gluconate in an alcohol base as the preferred antiseptic for central line insertion site preparation due to superior residual activity.

Question 3

A hospital experiences a cluster of E. coli infections in the neonatal ICU. Pulse-field gel electrophoresis (PFGE) reveals identical banding patterns in all isolates. This finding suggests:

Accepted Answer

A common clonal outbreak source requiring investigation

Answer

Identical PFGE banding patterns indicate that the isolates are clonally related, strongly suggesting a common source or transmission chain requiring a formal outbreak investigation.

Question 4

Which of the following best describes the purpose of a ventilator bundle in ICU patients?

Accepted Answer

To combine evidence-based interventions that collectively reduce VAP rates

Answer

A ventilator bundle groups multiple independent evidence-based practices — such as head-of-bed elevation and daily sedation vacations — which together achieve greater VAP reduction than any single measure.

Question 5

In the context of infection prevention program management, a process measure would BEST be exemplified by:

Accepted Answer

The percentage of staff who completed annual infection prevention competencies

Answer

Process measures evaluate whether recommended practices are being performed, such as training completion rates, whereas outcome measures (like CLABSI rates) reflect the end result.
