Free HHA Infection Control and Safety Questions and Answers 3

Question 1

When should an aide perform hand hygiene during patient care?

Accepted Answer

Before touching the patient, before clean procedures, after body fluid exposure, after touching the patient, and after touching the patient's surroundings (the WHO "5 Moments")

Answer

The WHO's Five Moments for Hand Hygiene provides a research-based framework that identifies the key points during care when hand hygiene is most critical to prevent infection transmission.

Question 2

A patient who is immunocompromised is at highest risk from:

Accepted Answer

Infection from microorganisms that would not normally cause disease in healthy individuals

Answer

Immunocompromised patients (e.g., those on chemotherapy or with HIV) have weakened defenses; opportunistic organisms that are harmless to healthy people can cause life-threatening infections in them.

Question 3

What is the purpose of the chain of infection model?

Accepted Answer

To identify the six links (agent, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host) so that any one can be broken to stop infection spread

Answer

Understanding the chain of infection helps aides identify intervention points (e.g., hand hygiene breaks the mode of transmission link, PPE blocks the portal of entry).

Question 4

A home is found to have cockroaches. Why is this a concern related to infection control?

Accepted Answer

Cockroaches can carry pathogens that contaminate food, surfaces, and supplies, increasing infection risk

Answer

Cockroaches are vectors that can transport bacteria (e.g., Salmonella, E. coli) on their bodies, contaminating food and surfaces and increasing infection risk for vulnerable patients.

Question 5

An aide accidentally splashes blood onto their eyes. The immediate action is to:

Accepted Answer

Flush the eyes immediately with clean water or saline for at least 15 minutes, then report the exposure per agency protocol

Answer

Immediate flushing for at least 15 minutes dilutes and removes pathogens. All blood/body fluid exposures must be reported immediately so post-exposure prophylaxis can be considered if needed.
