What is a Mass Casualty Incident (MCI) best defined as?
- A Any single event involving more than ten injured individuals
- B An event whose casualties overwhelm available healthcare resources
- C A disaster severe enough to require national or international aid
- D A routine emergency call that needs only standard staffing levels
Correct answer: An event whose casualties overwhelm available healthcare resources
An MCI is defined as an event where casualties exceed local resources and the healthcare system becomes overwhelmed.
In the concept of Surge Capacity, a critical component is described by the “4 S’s”. Which of the following is not one of those components?
- A Treating every patient exactly the same regardless of injury
- B Prioritizing those most likely to survive with available resources
- C Treating only the patients who happen to arrive at the scene first
- D Providing full intensive care to every patient who presents
Correct answer: Prioritizing those most likely to survive with available resources
The “4 S’s” in surge capacity include Staff, Space, Stuff, and System/Structure—not “Speed”.
During a surge scenario, a hospital may implement which of the following to expand capacity quickly?
- A Cancel elective procedures and discharge stable patients
- B Admit only new critical patients while neglecting current ones
- C Rely solely on outpatient facilities with no triage process
- D Deactivate the hospital incident command structure entirely
Correct answer: Cancel elective procedures and discharge stable patients
One key strategy in surge planning is to cancel elective procedures and expedite discharge of stable patients to free space and resources.
In the triage of an MCI, the principle of “greatest good for the greatest number” means:
- A Expanding services within the facility versus bringing in external resources
- B Relying solely on external field hospitals set up off site
- C Disregarding the facility's own internal bed capacity entirely
- D Delivering all patient care through telemedicine consultations only
Correct answer: Expanding services within the facility versus bringing in external resources
In disasters, resources are limited and triage aims to maximize survival by allocating care to those most likely to benefit.
Which triage tag color is used to identify patients who are walking wounded in a START (Simple Triage and Rapid Treatment) system?
- A To centralize decision making and coordinate resources across agencies
- B To allow every department to act fully independently of one another
- C To permanently replace the hospital's normal leadership structure
- D To delay allocation of resources until after the event is over
Correct answer: To centralize decision making and coordinate resources across agencies
In START triage, ambulatory patients with minor injuries are tagged green—“walking wounded”.
A hospital surge capacity plan described as “intrinsic surge” versus “extrinsic surge” refers to:
- A Only when the media reports large numbers of casualties arriving
- B When expected patient numbers exceed the hospital's daily capacity
- C Only after all available hospital resources have been depleted
- D Only when responding to a declared infectious-disease pandemic
Correct answer: When expected patient numbers exceed the hospital's daily capacity
Intrinsic surge uses internal hospital resources; extrinsic involves external support or resources outside the normal facility framework.
In a mass casualty event, what is the purpose of establishing an Incident Command System (ICS)?
- A Offering only luxury or elective treatments to patients
- B Care good enough to sustain life for most patients, though not full standard
- C Care that is identical in every respect to elective care
- D Withholding all care from the most critically injured patients
Correct answer: Care good enough to sustain life for most patients, though not full standard
ICS provides structure for unified command, coordination of personnel and resources, and effective communication during MCIs.
When would a hospital activate its disaster surge plan?
- A A routinely scheduled outpatient surgical procedure
- B A sudden explosion or earthquake with no warning
- C A planned community sporting or recreational event
- D A long-scheduled mass vaccination clinic for the public
Correct answer: A sudden explosion or earthquake with no warning
Surge plans are activated when demand exceeds routine capacity and normal operations cannot meet patient needs.
In a disaster surge, what does “sufficient care” vs “standard care” refer to?
- A Continuing to rely only on the current day-shift staff on duty
- B Cross-training staff, calling in extra personnel, and arranging external support
- C Depending only on untrained volunteers to fill staffing gaps
- D Waiting until on-duty staff are exhausted before activating backups
Correct answer: Cross-training staff, calling in extra personnel, and arranging external support
During surge, hospitals may shift from ideal (standard) care to “sufficient” care—meeting minimal acceptable outcomes given constrained resources.
Which of the following is a “no-notice” event typical of mass casualty scenarios?
- A Closing wards to free up additional nursing staff
- B Using non-traditional care areas such as conference rooms and hallways
- C Reducing the number of staffed inpatient beds available
- D Limiting all new patient admissions to the facility
Correct answer: Using non-traditional care areas such as conference rooms and hallways
No-notice events are sudden and unplanned, causing rapid patient influx that can overwhelm systems, characteristic of MCIs.
One key challenge in surge capacity is “staff”. Which strategy helps hospitals meet staff demands during an MCI?
- A Using only current day shift staff.
- B Cross-training staff, calling in additional personnel, having agreements for external support.
- C Only relying on volunteers with no training.
- D Waiting until staff are exhausted before activating backups.
Correct answer: Cross-training staff, calling in additional personnel, having agreements for external support.
Prepared surge plans include training, call-in lists, cross-training and external support agreements to maintain staff capacity during disasters.
Which of the following best represents “stuff” in surge capacity planning?
- A Only the physical hospital building and its structure
- B Supplies, equipment, pharmaceuticals, and protective gear
- C The hospital's policy and procedure documents
- D Only the human resources and staffing available
Correct answer: Supplies, equipment, pharmaceuticals, and protective gear
“Stuff” covers the physical supplies and equipment needed to support increased patient loads during a surge event.
In the early response to a mass casualty event, the emergency department should set up an external triage zone. Why?
- A To process patients outside the main ED and separate ambulatory from non-ambulatory
- B To deliberately delay all patient care until additional staff arrive
- C To make use of only the parking lot with no clinical resources
- D To restrict entry so only the most critical patients are admitted
Correct answer: To process patients outside the main ED and separate ambulatory from non-ambulatory
An external triage area helps sort incoming patients before entering the main ED, reduces overcrowding and improves flow in surge situations.
Which is a primary goal of disaster triage in a mass casualty incident?
- A Treat each patient strictly in chronological order of arrival
- B Sort and prioritize patients by severity and survivability
- C Focus exclusively on treating all pediatric patients first
- D Disregard condition and transport everyone directly to the ICU
Correct answer: Sort and prioritize patients by severity and survivability
Triage in MCIs aims to prioritise limited resources for those who will most likely survive with treatment, rather than strictly based on arrival or age.
Surge capacity also includes “space” expansion. Which of the following is a valid way to increase space during surge?
- A Closing existing wards in order to free up nursing staff
- B Using non-traditional areas such as conference rooms and hallways
- C Reducing the total number of available inpatient beds
- D Limiting new patient admissions to the facility entirely
Correct answer: Using non-traditional areas such as conference rooms and hallways
Expanding physical care areas using alternative spaces is a key strategy to increase capacity during a patient surge.
What role does the nursing staff play in mass casualty and surge capacity planning?
- A None - nurses respond only when specifically directed to
- B A key role in planning, drills, protocols, and implementing response
- C No role, since only administrative staff plan for disasters
- D Only bedside care, with no involvement in incident planning
Correct answer: A key role in planning, drills, protocols, and implementing response
Nurses are integral in disaster preparedness—participating in plan development, training, drills, and actual response to MCIs.
Which of the following is not a feature of surge capability (versus surge capacity)?
- A Caring for a large number of patients during a surge
- B Specialized resources for patients with high-acuity needs
- C The ability to manage only routine, day-to-day patient care
- D Capability to deliver specialized care during a surge event
Correct answer: The ability to manage only routine, day-to-day patient care
Surge capability refers to the ability to manage patients requiring specialized care during disasters, beyond just increased volume; routine care only is not that.
In mass casualty scenario triage, the “expectant” category (often black tag) means:
- A Immediate transport of these patients for definitive care
- B Injuries so severe that survival is unlikely with available resources
- C Minor injuries, allowing these patients to safely wait
- D A category for which treatment is deliberately never provided
Correct answer: Injuries so severe that survival is unlikely with available resources
“Expectant” patients are those unlikely to survive with available resources and thus are prioritised differently during disaster triage.
After the immediate response in a mass casualty event, one of the next phases is “recovery”. What does this phase involve?
- A Restoring operations to normal, debriefing staff, and revising plans
- B Only cleaning and decontaminating the facility after discharge
- C Deliberately disregarding any lessons learned from the event
- D Permanently closing the emergency department to new patients
Correct answer: Restoring operations to normal, debriefing staff, and revising plans
Recovery phase includes returning to normal operations, staff debriefing, performance evaluation and updating disaster plans for future events.
Which of the following best describes the difference between a “multiple casualty incident” and a “mass casualty incident”?
- A No role, since they only respond when explicitly told to
- B A key role in planning, drills, protocols, and response
- C None, because only administrative staff plan for disasters
- D Only direct patient care, with no role in incident planning
Correct answer: A key role in planning, drills, protocols, and response
The key difference is resource capacity: in MCIs the number of casualties exceeds resources, in multiple casualty incidents resources remain sufficient.
