CNA Safety and Infection Control 3

Question 1

The chain of infection requires all links to be present for disease to spread. Which link does hand hygiene MOST directly break?

Accepted Answer

Mode of transmission

Answer

Hand hygiene removes pathogens from the hands, directly interrupting the mode of transmission before organisms can reach a new host.

Question 2

A resident who is confused tries to climb over the side rail at night. What is the SAFEST initial intervention?

Accepted Answer

Lower the bed to the lowest position and place a floor mat

Answer

Lowering the bed and padding the floor reduces fall-related injury risk without using restraints, which require a physician order and can increase agitation.

Question 3

Which action by a CNA demonstrates correct technique when using an alcohol-based hand rub?

Accepted Answer

Apply enough product to cover all hand surfaces and rub until dry

Answer

Rubbing all surfaces until the product fully evaporates (approximately 20 seconds) is required for effective pathogen reduction with alcohol-based hand rub.

Question 4

A fire breaks out in the room next to a resident's room. Using the RACE acronym, what is the FIRST action?

Accepted Answer

Rescue residents in immediate danger

Answer

The R in RACE stands for Rescue — moving residents in immediate danger to safety is always the first priority.

Question 5

A CNA accidentally splashes blood on their face during a procedure. What is the FIRST action?

Accepted Answer

Flush the area with water for at least 15 minutes

Answer

Flushing mucous membranes or skin with water for 15 minutes is the immediate first-aid response to a bloodborne pathogen exposure.
