Colorful paper art displaying various hand hygiene related items for a knowledge quiz.

This hand hygiene quiz helps you check infection control basics and sharpen your handwashing steps. Answer 15 multiple-choice questions to spot gaps and build safer habits; when you're done, try the office hygiene quiz or the food hygiene quiz for broader practice.

What is the first step in proper handwashing with soap and water?
Rub hands together vigorously
Wet hands under running water
Apply soap to dry hands
Dry hands with a towel
The first step of effective handwashing is wetting hands under running water to help soap lather and loosen pathogens. Without wetting, soap cannot spread evenly across the skin.
How long should you rub your hands together when washing with soap to ensure effective cleaning?
10 seconds
20 seconds
30 seconds
5 seconds
Health authorities recommend scrubbing hands for at least 20 seconds to mechanically remove microorganisms. Shorter durations are less effective at dislodging pathogens.
Which method is considered best for drying hands after washing?
Air drying naturally
Wiping on clothing
Using a shared cloth towel
Using a single-use paper towel
Single-use paper towels effectively remove residual moisture and microbes and prevent cross-contamination. Shared or cloth towels can harbor and transfer pathogens.
When is it most appropriate to use an alcohol-based hand sanitizer instead of soap and water?
If soap and water are not available and hands are not visibly dirty
Before eating a meal at home
After using the restroom
When hands are visibly soiled
Hand sanitizer is recommended when hands are not visibly soiled and soap and water are unavailable. If hands are dirty, washing with soap and water is necessary to remove contaminants.
What is the primary active ingredient in most alcohol-based hand sanitizers?
Ethanol (ethyl alcohol)
Chlorhexidine gluconate
Quaternary ammonium compounds
Triclosan
Ethanol is the most common active ingredient in hand sanitizers because it effectively denatures proteins and disrupts microbial membranes. Other ingredients are less widely used.
Which handwashing action most effectively removes dirt and microbes from under the fingernails?
Rinsing with water only
Drying hands immediately
Applying hand sanitizer first
Scrubbing fingertips and under nails with soapy friction
Focusing on scrubbing fingertips and under the nails with soapy friction dislodges trapped dirt and pathogens. Simply rinsing or drying does not clean these areas effectively.
How does proper hand hygiene contribute to preventing the spread of healthcare-associated infections?
It increases skin moisture to protect integrity
It creates a physical barrier on the skin
It reduces microbial load on hands, interrupting transmission
It sterilizes all surfaces touched afterward
Effective hand hygiene lowers the number of microbes on hands, preventing their transfer between patients and surfaces. This interruption of transmission is key to infection control.
In which situation is handwashing with soap and water preferred over using alcohol-based hand sanitizer?
Before touching a patient
After using the restroom or when hands are visibly soiled
After wearing gloves
After contact with patient surroundings
Soap and water are necessary when hands are visibly dirty or after restroom use to physically remove dirt and organic material that sanitizer alone cannot clear.
What is the correct order of steps when using an alcohol-based hand rub?
Apply, rub palms, rub fingertips, rub until dry
Apply, rinse, rub palms, dry
Rub palms, apply, rub until dry, rub fingertips
Rub until dry, apply, rub palms, rub fingertips
The proper procedure is to apply the sanitiser, rub palms together, ensure coverage of fingertips and between fingers, and continue rubbing until hands are dry to ensure maximum microbial kill.
According to WHO's "Five Moments for Hand Hygiene," how many distinct times should healthcare workers clean their hands per patient encounter?
Four
Three
Five
Six
The WHO identifies five key moments: before touching a patient, before aseptic procedures, after body fluid exposure risk, after touching a patient, and after touching patient surroundings.
Which type of microorganism is most resistant to alcohol-based hand sanitizers?
Enveloped viruses like influenza
Spore-forming bacteria like Clostridium difficile
Non-enveloped viruses like Norovirus
Gram-positive bacteria like Staphylococcus
Clostridium difficile forms spores that are resistant to alcohol's mechanism of action. Handwashing with soap and water is required to remove these spores effectively.
Why is friction an essential component of effective handwashing?
It generates heat to kill microbes
It dilutes pathogens in water
It chemically inactivates enzymes
It physically removes microbes through mechanical action
Friction helps dislodge and lift microbes and dirt from the skin surface, allowing soap and water to wash them away. Without friction, pathogens remain attached.
After which of the following moments should a healthcare worker perform hand hygiene?
After removing examination gloves
Only before patient contact
Only at the start and end of a shift
Before donning gloves only
Hand hygiene should be performed after glove removal because gloves can have microtears or contamination during removal, posing a risk of pathogen transfer.
Which intervention is most effective for improving hand hygiene compliance in a hospital ward?
Strict penalties for noncompliance
Increased hand sanitizer sales
Strategic placement of reminders and dispensers at point of care
Daily email reminders to staff
Reminders and accessible dispensers at the point of care have been shown to significantly increase compliance by making hand hygiene convenient and top-of-mind.
What role does soap play in the removal of microbes compared to plain water?
Soap acts as a disinfectant on the skin
Soap coats microbes to inactivate them instantly
Soap increases skin pH to kill bacteria
Soap lowers surface tension and emulsifies oils that trap microbes
Soap molecules break down oils and fats on the skin that harbor microbes, emulsifying them so they can be rinsed away, whereas water alone cannot remove oily particles effectively.
Why are alcohol-based hand rubs ineffective against Clostridium difficile spores?
Spores lack protein structures alcohol targets
Spores are inactivated only by quaternary ammonium compounds
Spores are too large for alcohol molecules
Alcohol evaporates before penetrating spore coats
Alcohol evaporates quickly and cannot penetrate the resilient spore coat of C. difficile, leaving spores intact. Mechanical removal by washing is required to eliminate them.
For a patient under contact precautions with confirmed norovirus, which hand hygiene protocol is most appropriate for healthcare workers?
Use alcohol-based hand rub only
Perform handwashing with soap and water
Glove use alone is sufficient
Use hand rub then don gloves without washing
Norovirus is a non-enveloped virus resistant to alcohol rubs, so handwashing with soap and water is essential to physically remove the virus from hands.
How should hand hygiene frequency differ between an outpatient clinic and an intensive care unit (ICU)?
Frequency depends only on patient volume
Higher frequency in ICU due to more invasive procedures
Higher frequency in outpatient clinics
Same frequency in both settings
ICU settings involve more invasive procedures and critically ill patients, increasing contamination risk. Thus hand hygiene frequency is higher in the ICU.
A nurse draws blood and then proceeds to administer medication without changing gloves. What is the correct hand hygiene sequence?
Remove gloves, perform hand hygiene, don new gloves, then administer medication
Administer medication with same gloves, then wash hands
Wash hands first, then remove gloves
Disinfect gloves with sanitizer then administer medication
After contact with blood, gloves must be removed to avoid cross-contamination. Hand hygiene cleanses any potential contaminants before donning new gloves for medication administration.
According to surgical hand antisepsis guidelines, what is the recommended duration for applying antimicrobial scrub before orthopedic surgery?
1 minute
30 seconds
2 - 6 minutes
10 minutes
Surgical hand antisepsis requires 2 - 6 minutes of scrub time with an antimicrobial agent to achieve sufficient reduction of resident and transient flora before invasive procedures.
