settings?
A. To improve skin appearance
B. To prevent the spread of microorganisms
C. To replace environmental cleaning
D. To eliminate the need for gloves
Answer: B. To prevent the spread of microorganisms
Rationale: Hand hygiene is one of the most important measures for
preventing transmission of microorganisms between healthcare
workers, patients, surfaces, and equipment. It reduces the number of
potentially harmful organisms on the hands and interrupts chains of
infection.
2. Which microorganism transmission route is most directly
interrupted by effective hand hygiene?
A. Contact transmission
B. Genetic transmission
C. Radiation exposure
D. Inherited transmission
Answer: A. Contact transmission
,Rationale: Hand hygiene primarily interrupts contact transmission by
removing or inactivating microorganisms acquired through contact
with patients, contaminated surfaces, equipment, or body substances.
3. When should healthcare workers perform hand hygiene before
touching a patient?
A. Only when the patient requests it
B. Only after putting on gloves
C. Before direct contact with the patient
D. After leaving the healthcare facility
Answer: C. Before direct contact with the patient
Rationale: Hand hygiene before touching a patient protects the patient
from microorganisms carried on the healthcare worker’s hands and is
a fundamental component of safe patient care.
4. Which method is generally preferred when hands are not visibly
soiled and an appropriate alcohol-based hand rub is available?
A. Rinsing hands with cold water only
B. Wiping hands on a clean towel
C. Wearing two pairs of gloves
D. Using an alcohol-based hand rub
Answer: D. Using an alcohol-based hand rub
Rationale: Alcohol-based hand rub is generally preferred for routine
hand antisepsis when hands are not visibly dirty because it is rapid,
effective against many microorganisms, and readily accessible at the
point of care.
5. When should hands be washed with soap and water?
,A. When hands are visibly soiled
B. Only before entering a hospital
C. Only after removing a surgical mask

according to facility policy
D. Apply sanitizer only over the jewelry

appropriately cleaned according to facility policy

are visibly contaminated with blood?
A. Apply alcohol-based hand rub without washing
B. Wipe the hands on clothing
C. Put on another pair of gloves
D. Wash the hands with soap and water

A. Microorganisms can accumulate around and beneath nails
B. Nails prevent all contamination
C. Nail polish disinfects the fingers
D. Long nails improve hand-rubbing technique
Answer: A. Microorganisms can accumulate around and beneath

microorganisms. Keeping nails appropriately short and maintaining
good hand hygiene helps reduce microbial accumulation.
10. Which nail practice best supports effective infection
prevention?
