CNA Infection Control and Safety 3

Question 1

A resident with MRSA is on contact precautions. Which statement about their room placement is CORRECT?

Accepted Answer

A private room or cohorting with same-organism patients is preferred

Answer

Contact precautions ideally use a private room, or cohorting (placing patients with the same organism together) when a private room is unavailable.

Question 2

Which type of transmission requires an N95 respirator rather than a surgical mask?

Accepted Answer

Airborne transmission

Answer

Airborne precautions (e.g., tuberculosis, measles) require a fit-tested N95 respirator because particles remain suspended in the air over long distances.

Question 3

When changing a resident's soiled bed linens, the CNA should:

Accepted Answer

Roll soiled linen inward and place it directly in the linen bag

Answer

Rolling soiled linen inward contains contaminants and prevents dispersal of microorganisms into the air.

Question 4

The 'chain of infection' concept is used in infection control to:

Accepted Answer

Identify weak links that can be broken to prevent disease spread

Answer

Breaking any one link in the chain of infection — such as eliminating the reservoir or blocking transmission — prevents an infection from spreading.

Question 5

A CNA is caring for a resident with an indwelling urinary catheter. Which action BEST prevents a catheter-associated urinary tract infection (CAUTI)?

Accepted Answer

Maintain a closed drainage system and keep the bag below bladder level

Answer

Maintaining a closed drainage system and keeping the collection bag below bladder level prevents backflow and reduces CAUTI risk.
