Free HHA Infection Control and Safety Questions and Answers 3 — Questions and Answers
Question 1: When should an aide perform hand hygiene during patient care?
- Only before the visit begins and after leaving the home
- 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") (Correct answer)
- Only after removing gloves
- Only when hands are visibly soiled
Correct 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")
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:
- Environmental noise
- Infection from microorganisms that would not normally cause disease in healthy individuals (Correct answer)
- Excessive sunlight exposure
- Physical overexertion
Correct answer: Infection from microorganisms that would not normally cause disease in healthy individuals
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?
- To list all infectious diseases alphabetically
- 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 (Correct answer)
- To describe how antibiotics work
- To rank diseases by severity
Correct 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
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?
- Cockroaches only affect the patient's mental well-being
- Cockroaches can carry pathogens that contaminate food, surfaces, and supplies, increasing infection risk (Correct answer)
- Cockroaches only matter in hospital settings
- Cockroaches are a concern solely for property value
Correct answer: Cockroaches can carry pathogens that contaminate food, surfaces, and supplies, increasing infection risk
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:
- Rub the eyes vigorously with a dry cloth
- Flush the eyes immediately with clean water or saline for at least 15 minutes, then report the exposure per agency protocol (Correct answer)
- Continue the task and report at the end of the shift
- Apply antibiotic eye drops from the medicine cabinet
Correct answer: Flush the eyes immediately with clean water or saline for at least 15 minutes, then report the exposure per agency protocol
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.
Question 6: Cleaning versus disinfecting are different because:
- They are the same process with different names
- Cleaning physically removes dirt and organic matter; disinfecting kills or inactivates most pathogens on surfaces (Correct answer)
- Disinfecting is done before cleaning
- Cleaning eliminates all microorganisms including spores
Correct answer: Cleaning physically removes dirt and organic matter; disinfecting kills or inactivates most pathogens on surfaces
Cleaning (soap/water) must precede disinfection because organic matter inactivates many disinfectants. Together they form effective decontamination of home care equipment and surfaces.
