Q1. Which is the primary goal of an infection prevention and control program?
A. Eliminate all microorganisms from healthcare facilities
B. Prevent and reduce healthcare-associated infections
C. Increase antibiotic use
D. Reduce the number of healthcare workers
Answer: B. Prevent and reduce healthcare-associated infections
Rationale: Infection prevention and control programs are designed to prevent
transmission of infectious agents and reduce healthcare-associated infections
(HAIs) among patients, residents, visitors, and healthcare personnel.
Q2. Which component of the chain of infection is the organism that causes
disease?
A. Reservoir
B. Portal of entry
,C. Infectious agent
D. Susceptible host
Answer: C. Infectious agent
Rationale: The infectious agent is the microorganism capable of causing
infection, such as a bacterium, virus, fungus, or parasite.
Q3. Which action most directly interrupts transmission through contaminated
hands?
A. Increasing room temperature
B. Performing appropriate hand hygiene
C. Limiting documentation
D. Increasing patient room lighting
Answer: B. Performing appropriate hand hygiene
Rationale: Hand hygiene removes or kills microorganisms acquired through
contact and is one of the most important measures for interrupting transmission
in healthcare settings.
Q4. Which microorganism is classified as a bacterium?
A. Candida albicans
B. Influenza virus
C. Escherichia coli
D. Giardia intestinalis
Answer: C. Escherichia coli
Rationale: Escherichia coli is a bacterium. Candida is a fungus, influenza is a
virus, and Giardia is a protozoan parasite.
Q5. What is the most appropriate reason for using standard precautions?
,A. They apply only to patients with known infections
B. They assume every person may have potentially infectious material
C. They eliminate the need for hand hygiene
D. They replace transmission-based precautions
Answer: B. They assume every person may have potentially infectious material
Rationale: Standard precautions are used for all patients and are based on the
principle that blood, body fluids, non-intact skin, and mucous membranes may
contain transmissible infectious agents.
Q6. When should alcohol-based hand rub generally be used in healthcare
settings?
A. When hands are visibly dirty
B. When hands are not visibly soiled
C. Only after eating
D. Only before leaving the facility
Answer: B. When hands are not visibly soiled

Q7. Which item is considered personal protective equipment (PPE)?
A. Blood pressure machine
B. Stethoscope
C. Gloves
D. Medication cart
Answer: C. Gloves
Rationale: Gloves are PPE used to protect healthcare personnel from contact
with potentially infectious materials and to reduce contamination of hands.
, Q8. Which transmission-based precaution is appropriate for a patient with
suspected measles?
A. Contact precautions only
B. Droplet precautions only
C. Airborne precautions
D. Protective environment only
Answer: C. Airborne precautions
Rationale: Measles is transmitted through airborne particles and requires
airborne infection isolation measures, including appropriate respiratory
protection and an appropriate isolation environment.
Q9. Which disease commonly requires droplet precautions?
A. Measles
B. Pulmonary tuberculosis
C. Pertussis
D. Scabies
Answer: C. Pertussis
Rationale: Pertussis is transmitted primarily through respiratory droplets and
requires droplet precautions in addition to standard precautions.
Q10. Which condition commonly requires contact precautions?
A. Clostridioides difficile infection
B. Measles
C. Pulmonary tuberculosis
D. Uncomplicated influenza
Answer: A. Clostridioides difficile infection
