DCW - Direct Care Worker Infection Control and Prevention Questions and Answers

Question 1

Which of the following is the MOST critical step for a Direct Care Worker to take to break the chain of infection?

Accepted Answer

Proper and frequent hand hygiene

Answer

Proper and frequent hand hygiene is considered the single most effective way to prevent the spread of infections. It breaks the 'mode of transmission' link in the chain of infection by removing pathogens from the hands of the caregiver.

Question 2

A client has a known infection that is spread through contact with their wound drainage. When providing care that may involve touching the client or their linens, what Personal Protective Equipment (PPE) should the DCW wear at a minimum?

Accepted Answer

Gloves and gown

Answer

For contact precautions, which are used for infections spread by direct or indirect contact, the CDC recommends wearing both gloves and a gown to prevent the transmission of pathogens from the patient or their environment to the healthcare worker.

Question 3

When washing hands with soap and water, what is the minimum amount of time a DCW should scrub their hands together vigorously?

Accepted Answer

20 seconds

Answer

The Centers for Disease Control and Prevention (CDC) recommends scrubbing hands with soap and water for at least 20 seconds to effectively remove germs. A common tip is to hum the 'Happy Birthday' song twice.

Question 4

How should a DCW handle a client's soiled linens that are contaminated with body fluids?

Accepted Answer

Roll them away from the body and place them in a designated, leak-proof bag.

Answer

Soiled linens should be handled with minimal agitation to prevent airborne contamination. They should be rolled carefully, held away from the caregiver's body, and placed directly into a leak-proof bag or container designated for contaminated laundry.

Question 5

The 'chain of infection' describes how pathogens are transmitted. Which of the following represents the 'portal of entry' link in this chain?

Accepted Answer

A break in a client's skin

Answer

A portal of entry is the path by which an infectious agent enters a new host. Examples include non-intact skin (like a cut or wound), mucous membranes, and the respiratory tract. A contaminated object is a 'reservoir', a bacterium is the 'infectious agent', and a person with a weakened immune system is a 'susceptible host'.
