CNA Isolation Precautions 2

Question 1

A resident is diagnosed with MRSA (Methicillin-resistant Staphylococcus aureus) in a wound. Which type of isolation precautions is required?

Accepted Answer

Contact precautions

Answer

MRSA is transmitted through direct contact with infected wounds or contaminated surfaces. Contact precautions are required to prevent spread to other residents and staff.

Question 2

Influenza (flu) spreads primarily through respiratory droplets produced when an infected person coughs or sneezes. Which precaution type is required?

Accepted Answer

Droplet precautions

Answer

Influenza spreads through large respiratory droplets (not tiny airborne particles) that fall quickly and travel less than 6 feet. Droplet precautions are required.

Question 3

In what order should personal protective equipment (PPE) be put on (donned) before entering a contact precaution room?

Accepted Answer

Gown first, then mask (if needed), then eye protection, then gloves last

Answer

The standard PPE donning sequence is: gown first (provides body coverage), then mask/respirator, then eye protection, then gloves last (gloves go over gown cuffs to prevent gaps).

Question 4

Tuberculosis (TB) requires airborne precautions. What type of room is needed for a resident with active TB?

Accepted Answer

Airborne Infection Isolation Room (AIIR) with negative air pressure

Answer

Active TB requires an Airborne Infection Isolation Room (AIIR) with negative pressure — air is drawn in from the hallway and exhausted outside or filtered, preventing TB bacilli from spreading to other areas of the facility.

Question 5

Standard precautions should be used:

Accepted Answer

With every resident, regardless of their diagnosis or infection status

Answer

Standard precautions are the baseline infection prevention practices applied with all residents in all settings, regardless of whether a resident has a known infectious disease, because blood and body fluids may harbor undiagnosed pathogens.
