Question 3

A patient diagnosed with MRSA (Methicillin-resistant Staphylococcus aureus) skin infection should be placed on which isolation precaution?

Accepted Answer

Contact precautions with gloves and gown

Answer

MRSA is primarily transmitted via direct or indirect contact; contact precautions (gown and gloves upon room entry) are required to prevent spread of this drug-resistant organism.

Question 4

What is the correct order for doffing (removing) PPE after leaving an isolation room?

Accepted Answer

Gloves, gown, eye protection, mask/respirator

Answer

PPE is removed in the order gloves, gown, eye protection, then mask last — this sequence keeps the most contaminated items (gloves/gown) removed first while the cleaner mask protects against facial contamination until the end.

Question 5

Which class of microorganism is most resistant to standard chemical disinfectants and requires sterilization to eliminate?

Accepted Answer

Bacterial endospores such as those from Bacillus and Clostridium species
