HCA - Health Care Assistant Infection Prevention and Control Questions and Answers

Question 1

A resident is on contact precautions due to an infection with Clostridioides difficile (C. diff). Which of the following actions by the Health Care Assistant is most appropriate?

Accepted Answer

Wearing a gown and gloves for all interactions with the resident and their environment.

Answer

Contact precautions require wearing a gown and gloves for all interactions with the patient or their environment to prevent the spread of pathogens through direct or indirect contact. C. diff spores are not effectively killed by alcohol-based hand rubs, so handwashing with soap and water is preferred. Closing the door is typical for airborne precautions, and an N95 respirator is used for airborne pathogens, not those spread by contact.

Question 2

Which of the following is the single most effective way to break the chain of infection?

Accepted Answer

Performing frequent and proper hand hygiene.

Answer

Proper hand hygiene, including handwashing with soap and water or using an alcohol-based hand sanitizer, is recognized as the single most effective measure to prevent the spread of infections in healthcare settings. It breaks the chain of infection by removing or inactivating pathogens on the hands, which are a primary mode of transmission.

Question 3

A Health Care Assistant is preparing to assist a nurse with a sterile dressing change. This procedure requires the use of surgical asepsis. What is the primary goal of surgical asepsis?

Accepted Answer

To eliminate all microorganisms and their spores.

Answer

Surgical asepsis, or sterile technique, aims to create an environment completely free of all microorganisms, including spores. This is different from medical asepsis ('clean technique'), which focuses on reducing the number of pathogens to prevent their spread.

Question 4

In the chain of infection, a resident with a weakened immune system due to age and chronic illness represents which link?

Accepted Answer

Susceptible Host

Answer

A susceptible host is an individual who is at risk of becoming infected. Factors like age, chronic illness, and a weakened immune system make a person more vulnerable to infection, thus making them a susceptible host in the chain of infection.

Question 5

When removing Personal Protective Equipment (PPE) after caring for a resident in isolation, which item should the Health Care Assistant remove first?

Accepted Answer

Gloves

Answer

Gloves are considered the most contaminated piece of PPE and should be removed first to prevent contaminating other surfaces and oneself during the doffing process. The general principle is to remove the most contaminated items first, followed by performing hand hygiene.
