DCW - Direct Care Worker Infection Control and Prevention Questions and Answers — 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?
- Wearing a new uniform every day
- Proper and frequent hand hygiene (Correct answer)
- Opening windows to air out rooms
- Using hand lotion to prevent dry skin
Correct answer: Proper and frequent hand hygiene
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?
- Gloves and gown (Correct answer)
- Mask and goggles
- Gloves only
- Gown and shoe covers
Correct answer: Gloves and gown
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?
- 5 seconds
- 10 seconds
- 20 seconds (Correct answer)
- 60 seconds
Correct answer: 20 seconds
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?
- Shake them out to remove any solid debris before washing.
- Wash them separately with cold water and regular detergent.
- Place them on the floor until they can be taken to the laundry.
- Roll them away from the body and place them in a designated, leak-proof bag. (Correct answer)
Correct answer: Roll them away from the body and place them in a designated, leak-proof bag.
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?
- A person with a weakened immune system
- A contaminated piece of medical equipment
- A break in a client's skin (Correct answer)
- A microorganism like a bacterium or virus
Correct answer: A break in a client's skin
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'.
Question 6: After providing care to a client, a DCW needs to remove their Personal Protective Equipment (PPE) which includes a gown, gloves, and a face mask. What is the correct order for removal (doffing)?
- Mask, gown, gloves
- Gown, mask, gloves
- Gloves, gown, mask (Correct answer)
- Mask, gloves, gown
Correct answer: Gloves, gown, mask
The CDC recommends a specific sequence for doffing PPE to minimize self-contamination. Generally, the most contaminated items are removed first. The correct order is to remove gloves, then the gown, and finally the mask (which is often removed outside the client's room). Hand hygiene should be performed after each step. A common mnemonic for doffing is to remove items in alphabetical order: Gloves, Goggles, Gown, Mask.
