1. Which statement best describes the primary purpose of hand hygiene
in healthcare settings?
A. To eliminate every microorganism from the hands permanently
B. To replace the need for personal protective equipment
C. To reduce the transmission of microorganisms between healthcare
workers, patients, and the environment
D. To prevent only infections caused by bacteria
Rationale: Hand hygiene is one of the most important measures for
preventing transmission of microorganisms in healthcare. It reduces
contamination of the hands and interrupts routes by which pathogens can
spread between patients, healthcare workers, and surfaces.
2. Which two methods constitute the principal forms of hand hygiene in
routine healthcare practice?
,A. Surgical gloves and sterile gowns
B. Handwashing with soap and water and cleaning with an appropriate
alcohol-based hand rub
C. Antiseptic wipes and surgical masks
D. Plain-water rinsing and drying with clothing
Rationale: Routine hand hygiene is primarily performed using soap and
water or an appropriate alcohol-based hand rub. The choice depends on
the clinical circumstances, including whether hands are visibly soiled and
the suspected or known pathogen.
3. When should a healthcare worker generally use soap and water rather
than alcohol-based hand rub?
A. Whenever entering any hospital corridor
B. Whenever gloves are worn
C. When hands are visibly dirty or soiled, after certain gastrointestinal
infections, or when otherwise indicated by infection-control guidance
D. Only before eating lunch
Rationale: Alcohol-based hand rub is highly effective for many organisms
but is not appropriate when hands are visibly soiled and may be less
effective against some organisms or situations requiring mechanical
removal with soap and water.
, 4. What is the most appropriate duration for applying an alcohol-based
hand rub?
A. Approximately 2 seconds
B. Approximately 5 seconds
C. Long enough to cover all hand surfaces and allow the hands to dry
completely, following the product's recommended application time
D. Exactly 60 minutes
Rationale: Effective hand-rub application requires sufficient product and
coverage of all hand surfaces until the hands are dry. Product instructions
should be followed because formulations can differ.
5. Which action is essential when performing handwashing with soap
and water?
A. Rinse before applying soap and immediately leave the sink
B. Wet the hands, apply soap, thoroughly rub all hand surfaces, rinse, and
dry with an appropriate clean or disposable towel
C. Apply soap only to the palms
D. Dry the hands on a used clinical gown
Rationale: Effective handwashing involves mechanical rubbing of all hand
surfaces followed by thorough rinsing and appropriate drying. Inadequate
coverage or drying can leave microorganisms on the hands or facilitate
transfer to surfaces.
, 6. Which area is commonly missed during routine hand hygiene?
A. The center of the palm only
B. Thumbs, fingertips, between the fingers, and the backs of the hands
C. The wristwatch only
D. The forearm exclusively
Rationale: People frequently miss areas such as the thumbs, fingertips,
interdigital spaces, and backs of the hands. A systematic rubbing technique
helps ensure complete coverage.
7. Why is hand drying an important component of hand hygiene?
A. Drying has no relationship to infection prevention.
B. Wet hands can transfer microorganisms more readily than properly
dried hands.
C. Drying restores all microorganisms to the skin.
D. Drying eliminates the need for handwashing.
Rationale: Moisture facilitates transfer of microorganisms from hands to
other surfaces. Proper drying therefore contributes to effective hand
hygiene and reduces environmental contamination.
8. Which statement about alcohol-based hand rub is correct?
A. It should be applied only to the fingertips.
B. It is effective only when the hands are visibly dirty.
