RDA Infection Control and Barrier Techniques 2

Question 1

Which type of glove is NOT acceptable for use during patient examination and treatment procedures in dentistry?

Accepted Answer

Household utility gloves used for patient care

Answer

Household utility gloves are intended for cleaning and disinfection tasks, not patient care; using them for treatment would be inappropriate and violate infection control standards.

Question 2

What is the purpose of an alcohol-based hand rub (ABHR) in dental infection control?

Accepted Answer

It rapidly reduces microbial counts on hands when they are not visibly soiled

Answer

ABHR rapidly reduces transient microorganisms on hands that are not visibly soiled; when hands are visibly soiled, soap and water must be used instead.

Question 3

Respiratory hygiene and cough etiquette in the dental waiting room includes which of the following?

Accepted Answer

Providing tissues, no-touch waste containers, and hand hygiene supplies at the front desk

Answer

Providing tissues, waste containers, and hand hygiene resources at the point of patient entry is the CDC-recommended respiratory hygiene strategy for preventing respiratory infection spread.

Question 4

Which statement about latex allergy in the dental setting is correct?

Accepted Answer

Dental teams must be prepared to manage latex allergy reactions and offer latex-free alternatives

Answer

Both patients and staff can have latex allergies, so dental offices must stock latex-free alternatives (nitrile, vinyl) and have protocols to manage allergic reactions.

Question 5

What is the minimum contact time required for most intermediate-level surface disinfectants to be effective?

Accepted Answer

The wet contact time specified on the product label (usually 1–10 minutes)

Answer

Disinfectants must remain wet on a surface for the contact time listed on their EPA-registered label to achieve the claimed level of disinfection.
