HCA Infection Prevention and Control 2

Question 1

Which type of transmission occurs when infected droplets travel more than 6 feet through the air and remain suspended for extended periods?

Accepted Answer

Airborne transmission

Answer

Airborne transmission involves tiny particles (droplet nuclei) that remain suspended in air and can travel long distances, unlike larger droplets that fall quickly.

Question 2

A health care assistant is caring for a patient with C. difficile (C. diff). Which hand hygiene method is most effective after removing gloves?

Accepted Answer

Soap and water handwashing

Answer

Soap and water is required for C. diff because alcohol-based products are ineffective against C. diff spores; mechanical friction with water physically removes the spores.

Question 3

What does the acronym PPE stand for in infection control?

Accepted Answer

Personal Protective Equipment

Answer

PPE stands for Personal Protective Equipment, which includes gloves, gowns, masks, and eye protection used to protect both patients and healthcare workers.

Question 4

When donning (putting on) PPE, what is the correct order of steps?

Accepted Answer

Gown, mask, eye protection, gloves

Answer

The CDC-recommended donning order is gown first, then mask/respirator, then eye protection, then gloves so that each item protects the next.

Question 5

A patient is placed on droplet precautions. How far away from the patient should a surgical mask be worn by the HCA when entering the room?

Accepted Answer

Whenever entering the room regardless of distance

Answer

Droplet precautions require wearing a surgical mask upon entering the patient's room, regardless of the distance, because droplets can travel unpredictably within the enclosed space.
