Question 1

When donning PPE before entering a contact isolation room, which item should be put on first?

The gown is donned first because it covers the largest body surface area; gloves are applied last and pulled over the gown cuffs.

Question 2

What is the single most effective method for preventing the spread of healthcare-associated infections?

Accepted Answer

Hand hygiene with soap and water or alcohol-based hand rub

Answer

Hand hygiene is the single most effective measure for preventing transmission of pathogens in healthcare settings, as recommended by the CDC and WHO.

Question 3

When removing PPE after caring for a patient on contact precautions, what is the correct sequence?

Accepted Answer

Gloves, goggles or face shield, gown, mask or respirator

Answer

Per CDC guidelines, gloves (most contaminated) are removed first, followed by eye protection, then gown, with the mask removed last to minimize self-contamination.

Question 4

During a sterile dressing change, which action would break sterile technique?

Accepted Answer

Reaching over the sterile field to arrange supplies

Answer

Reaching over a sterile field contaminates it because unsterile clothing or arms pass directly above the field, allowing microorganism fallout.

Question 5

A patient is admitted with a Clostridium difficile (C. diff) infection. Which precautions should be initiated in addition to standard precautions?

Accepted Answer

Contact precautions

Answer

C. difficile spreads via the fecal-oral route through contact with spore-contaminated surfaces or hands, requiring contact precautions.
