Subtopic 1: Fundamentals of Outbreak Management in
Healthcare Settings
Questions 1–20
Question 1
A cluster of three patients develops similar respiratory symptoms within 48 hours on the
same hospital ward. What is the nurse's priority action?
A. Isolate all patients in the ward
B. Report the cluster to the infection control team
C. Administer broad-spectrum antibiotics
D. Contact environmental services for deep cleaning
Correct answer: B
Rationale: Early identification and prompt reporting to the infection control team are
critical in initiating an outbreak investigation and control measures.
Question 2
Which of the following best describes the goal of outbreak management in a clinical
setting?
A. Eliminate all microorganisms from the hospital environment
B. Identify, control, and prevent further spread of infection
C. Reduce patient complaints regarding infection control
D. Document infection cases for legal purposes
Correct answer: B
Rationale: The primary goal of outbreak management is to rapidly control and prevent the
spread of disease among patients and healthcare workers.

Question 3
What is the first step in the outbreak investigation process?
A. Confirm the existence of an outbreak
B. Collect laboratory samples
C. Interview exposed staff
D. Notify local health authorities
Correct answer: A
Rationale: Determining whether the number of cases exceeds the expected baseline is
essential to confirm an outbreak.
Question 4
Which metric best helps identify the rate of infection during an outbreak?
A. Case-fatality ratio
B. Attack rate
C. Incubation period
D. Reproduction number (R₀)
Correct answer: B
Rationale: The attack rate measures the proportion of exposed individuals who become ill,
helping quantify outbreak severity.
Question 5
What defines a “nosocomial outbreak”?
A. Community-based infection brought into the hospital
B. Infection acquired within a healthcare facility
, 4
C. Bioterrorism-related infection
D. Infection that only affects healthcare workers
Correct answer: B
Rationale: Nosocomial outbreaks are healthcare-associated infections that occur within
the facility and often involve patient-to-patient or staff-to-patient transmission.
Question 6
Which of the following should be the nurse’s initial action after detecting a possible
hospital-acquired infection cluster?
A. Begin administering antivirals
B. Isolate affected individuals and notify infection prevention
C. Inform hospital visitors
D. Document the cases for the quarterly report
Correct answer: B
Rationale: Isolation and prompt reporting limit further exposure and initiate a formal
investigation.
Question 7
In an outbreak of Clostridioides difficile, what environmental measure is crucial?
A. Use of alcohol-based sanitizers
B. Cleaning with bleach-based disinfectants
C. Daily mopping with plain water
D. Use of UV light only
Correct answer: B
