the spread of infection in healthcare settings?
A. Wearing gloves only when performing invasive procedures
B. Using hand sanitizer only when hands look dirty
C. Proper hand hygiene
D. Wearing a mask at all times
Hand hygiene is the single most effective measure to prevent the
transmission of pathogens in healthcare settings.
2. Standard precautions are applied:
A. Only to patients with known infections
B. Only in surgical units
C. To all patients, regardless of infection status
D. Only when handling blood
Standard precautions are applied universally to prevent exposure to
blood and body fluids from all patients.
3. Which of the following is considered a vector in disease
transmission?
,A. Contaminated water
B. Mosquito
C. Sneezing
D. Contaminated surfaces
Vectors are living organisms that transmit infectious agents between
humans or from animals to humans.
4. A nurse is caring for a patient with tuberculosis. Which isolation
precaution is appropriate?
A. Contact
B. Droplet
C. Airborne
D. Standard
Tuberculosis is transmitted via airborne particles; thus, airborne
precautions, including N95 masks, are required.
5. Which of the following is the correct sequence for donning
personal protective equipment (PPE)?
A. Gloves → Gown → Mask → Eye protection
B. Mask → Gloves → Gown → Eye protection
C. Gown → Mask → Eye protection → Gloves
D. Mask → Gown → Gloves → Eye protection
The proper sequence reduces the risk of self-contamination when
putting on PPE.
6. The most important reason for using alcohol-based hand rubs
over soap and water is:
,A. They are cheaper
B. They smell better
C. They are more effective at killing most pathogens quickly
D. They remove visible dirt better
Alcohol-based hand rubs kill most pathogens efficiently and are
convenient when hands are not visibly soiled.
7. Which of the following organisms is known for forming spores
and being resistant to disinfectants?
A. Staphylococcus aureus
B. Escherichia coli
C. Clostridium difficile
D. Influenza virus
Clostridium difficile produces spores that are highly resistant to heat
and many chemical disinfectants.
8. When cleaning a patient’s room after discharge, which solution is
most effective against C. difficile spores?
A. 70% ethanol
B. 50% bleach solution
C. Sodium hypochlorite (bleach) solution at appropriate

Bleach solutions are effective in destroying spores, which are
resistant to alcohol-based cleaners.
9. Which of the following is considered a fomite?
, A. Tick
B. Bed linens
C. Cough droplets
D. Mosquito
Fomites are inanimate objects that can carry infectious agents, such
as bedding, doorknobs, or medical equipment.
10. Droplet precautions are necessary for infections transmitted by:
A. Airborne particles <5 µm
B. Large respiratory droplets >5 µm
C. Contaminated water
D. Bloodborne exposure
Droplet precautions protect against infections spread by large
respiratory droplets, such as influenza or meningitis.
11. The proper way to remove gloves to prevent contamination is:
A. Pull off both gloves together quickly
B. Peel one glove off from the inside, then remove the other by
sliding fingers inside the glove
C. Wash hands while wearing gloves
D. Shake off gloves into the trash
Proper glove removal prevents contamination of the hands with
pathogens present on the glove surfaces.
12. Which is the primary goal of infection control programs in
healthcare facilities?
A. Reduce paperwork
B. Prevent healthcare-associated infections (HAIs)
