HCA Infection Prevention and Control 3

Question 1

A resident in a long-term care facility has MRSA in a wound. Which type of precautions should the HCA implement?

Accepted Answer

Contact precautions

Answer

MRSA is spread primarily through direct or indirect contact, so contact precautions — including gloves and gown — are required to prevent transmission.

Question 2

Which of the following best describes the 'chain of infection'?

Accepted Answer

The series of elements that must be present for an infection to spread

Answer

The chain of infection is a model with six links — infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host — all of which must be present for infection to occur.

Question 3

How long should proper handwashing with soap and water take according to CDC guidelines?

Accepted Answer

At least 20 seconds

Answer

The CDC recommends scrubbing hands with soap and water for at least 20 seconds to effectively remove most germs and contaminants.

Question 4

A patient with active pulmonary tuberculosis (TB) requires which type of isolation room?

Accepted Answer

Negative-pressure (airborne infection isolation) room

Answer

TB requires a negative-pressure airborne infection isolation room (AIIR), which pulls air inward and prevents infectious particles from escaping into hallways.

Question 5

When removing (doffing) contaminated PPE, what should be removed FIRST?

Accepted Answer

Gloves

Answer

Gloves are removed first during doffing because they are the most contaminated item and removing them first prevents contamination of other PPE and skin during the removal process.
