HAC Safety & Infection Control 2

Question 1

Which isolation precaution category requires a dedicated HEPA-filtered negative-pressure room?

Accepted Answer

Airborne infection isolation

Answer

Airborne infection isolation rooms maintain negative pressure with ≥12 air changes per hour and HEPA filtration to prevent spread of pathogens like M. tuberculosis.

Question 2

Under OSHA's Bloodborne Pathogens Standard, how often must employers offer Hepatitis B vaccination to at-risk employees at no cost?

Accepted Answer

Within 10 days of assignment to at-risk duties

Answer

OSHA 29 CFR 1910.1030 requires employers to offer HBV vaccination within 10 working days of an employee's initial assignment to tasks with occupational exposure.

Question 3

A healthcare analyst notices surgical site infection rates spike following a HVAC maintenance outage. Which infection control measure is most directly implicated?

Accepted Answer

Positive-pressure airflow in ORs

Answer

Operating rooms require positive-pressure ventilation to prevent environmental pathogens from entering the sterile field; HVAC failure compromises this barrier.

Question 4

The CDC's Healthcare Infection Control Practices Advisory Committee (HICPAC) Tier 1 precautions are applied to:

Accepted Answer

All patients regardless of diagnosis

Answer

Tier 1 (Standard Precautions) apply to all patients at all times because any patient may harbor unrecognized infectious agents.

Question 5

Which metric best measures the effectiveness of a hospital's central-line-associated bloodstream infection (CLABSI) prevention program?

Accepted Answer

Standardized Infection Ratio (SIR) compared to national baseline

Answer

The SIR adjusts for patient risk and facility type, providing a risk-stratified comparison to the NHSN national baseline to reflect true prevention effectiveness.
