25 practice questions

1. The National Incident Management System (NIMS) was created mainly to:

   1. A. Replace state EMS laws with a single federal EMS code
   2. B. Fund local EMS agencies after declared disasters
   3. C. Set national triage protocols for all hospitals
   4. D. Give all agencies one shared way to manage incidents
   Show answer

   Answer: D. Give all agencies one shared way to manage incidents

   NIMS, issued by FEMA under the Department of Homeland Security, gives responders at every level a common framework, structure, and language for managing incidents of any size. It does not replace state EMS law, serve as a funding program, or dictate hospital triage.

2. NIMS is designed to be used for:

   1. A. Federally declared disasters and terrorism
   2. B. Incidents of any size, cause, or complexity
   3. C. Incidents that involve more than ten patients
   4. D. Events that cross a state or national border
   Show answer

   Answer: B. Incidents of any size, cause, or complexity

   NIMS is scalable and all-hazards: the same principles manage a two-car crash and a hurricane. Limiting it to declared disasters or large patient counts is a common misconception that leads to poor organization on the many smaller incidents.

3. The Incident Command System (ICS) used in NIMS grew out of:

   1. A. FIRESCOPE, after 1970s California wildfires
   2. B. Military field hospitals in the Korean War
   3. C. The 9/11 Commission report on the 2001 attacks
   4. D. Hospital disaster drills in the early 1990s
   Show answer

   Answer: A. FIRESCOPE, after 1970s California wildfires

   ICS was developed by FIRESCOPE after wildfires in the 1970s exposed problems with communication, terminology, and coordination among agencies. NIMS later adopted ICS nationally; the 2001 attacks prompted that adoption but did not create ICS.

4. The five major functional areas of ICS are command, operations, planning, logistics, and:

   1. A. Public information
   2. B. Safety and security
   3. C. Finance/administration
   4. D. Medical and health services
   Show answer

   Answer: C. Finance/administration

   Command, operations, planning, logistics, and finance/administration are the five major ICS functions. Public information and safety are command staff positions that support the incident commander, not general staff sections.

5. On a small incident, the incident commander does not fill any section chief positions. This means that:

   1. A. The IC personally handles every ICS function
   2. B. Planning and logistics functions are skipped
   3. C. The functions are handed to dispatch to manage
   4. D. The incident is too small to need ICS
   Show answer

   Answer: A. The IC personally handles every ICS function

   Any ICS function that is not delegated stays with the incident commander. On a small call one person may cover all five functions, and positions are filled only as the incident grows (the modular principle). The functions still exist even when no one else fills them: someone must still plan and arrange supplies. Dispatch supports the incident but does not take over command functions. ICS applies to incidents of every size, so no incident is too small for it.

6. The NIMS principle of 'unity of command' means that:

   1. A. Every agency on scene shares a single radio
   2. B. All agencies agree on one set of objectives
   3. C. The IC must be from the agency with authority
   4. D. Each responder reports to only one supervisor
   Show answer

   Answer: D. Each responder reports to only one supervisor

   Unity of command means every person has one designated supervisor, which prevents conflicting orders. Agencies agreeing on shared objectives describes unified command, a different concept that is often confused with it.

7. Under NIMS, the recommended span of control for one supervisor is:

   1. A. Eight to twelve people, with ten ideal
   2. B. One to three people, with two ideal
   3. C. Three to seven people, with five ideal
   4. D. Up to fifteen people if radios work
   Show answer

   Answer: C. Three to seven people, with five ideal

   NIMS (2017) calls one supervisor to five subordinates the optimal span and treats it as a guideline. FEMA ICS training gives the working range as about 3 to 7. Spans of 8 to 12 overload a supervisor and weaken safety and accountability. Spans of 1 to 3 tie up supervisors that the incident needs elsewhere. Radio contact is not supervision, so good radios do not let one person safely manage 15.

8. You are the triage unit leader at a bus crash and find that 11 EMTs are now reporting directly to you. The best ICS response is to:

   1. A. Keep all 11 working and simply use the radio more
   2. B. Split them into teams with their own leaders
   3. C. Send the extra EMTs back to their stations
   4. D. Ask the IC to take over the triage function
   Show answer

   Answer: B. Split them into teams with their own leaders

   Eleven direct reports exceed the manageable span of control, so you should organize the crews into smaller teams, each with a leader who reports to you. The resources are still needed, so sending them away is wrong, and pushing the problem up to the IC breaks the modular structure.

9. A paramedic unit self-dispatches to a large MCI and goes straight to the patients without reporting in. The main problem is that:

   1. A. The crew loses its legal protection for care
   2. B. Their protocols no longer apply on the scene
   3. C. It forces the IC to switch to unified command
   4. D. Command cannot track or assign that crew
   Show answer

   Answer: D. Command cannot track or assign that crew

   Under NIMS, every arriving resource checks in, usually at staging or the command post, so command knows who is on scene, can assign them where they are needed, and can account for them if conditions change. Freelancing crews disrupt the plan and may be missed in an evacuation or roll call. Freelancing does not strip a crew of legal protection or suspend its protocols, and it does not change the command model; the problem is accountability and coordination.

10. A fender-bender grows into a 6-vehicle crash with 14 patients. As more units arrive, the IC adds a triage group and a transport group. This shows the ICS principle of:

    1. A. Unity of command
    2. B. Unified command
    3. C. Modular organization
    4. D. Common terminology use
    Show answer

    Answer: C. Modular organization

    Modular organization means positions are activated as the incident grows and released as it shrinks. Unity of command is about each person having one supervisor, and unified command is shared command among agencies, neither of which describes adding positions.

11. A fire chief at a chemical plant leak tells the EMS lieutenant, 'Our goal for the next hour is to remove all patients from the hot zone.' Choosing how crews will do it comes next. This shows:

    1. A. Management by objectives
    2. B. Unity of command
    3. C. Span of control
    4. D. Integrated communications
    Show answer

    Answer: A. Management by objectives

    Management by objectives means the IC first sets clear, measurable objectives and then selects strategies and tactics to meet them. Span of control concerns how many people one supervisor manages, which this statement does not address.

12. The incident action plan (IAP) is best described as a document that:

    1. A. Records each patient's care and final destination
    2. B. Lists objectives and assignments for a set period
    3. C. Sets out the agency's yearly disaster plan
    4. D. Logs each unit's arrival time at check-in
    Show answer

    Answer: B. Lists objectives and assignments for a set period

    The IAP states the objectives, strategies, assignments, and support for an operational period. On small incidents it may be oral; on larger ones the planning section writes it. Patient records are kept on tags and transport logs, arrival times on the check-in list, and the agency's standing disaster plan is a separate emergency operations plan.

13. The length of time covered by an incident action plan is called the:

    1. A. Response interval
    2. B. Operational period
    3. C. Command window
    4. D. Resource activation cycle
    Show answer

    Answer: B. Operational period

    An operational period is the time set for carrying out a given IAP, often 12 hours on large incidents. At its end the plan is reviewed and a new one is written for the next period.

14. In ICS, accountability for every responder on scene is maintained mainly by:

    1. A. Each supervisor tracking assigned people
    2. B. The public information officer's log
    3. C. The dispatch center listening to the radio
    4. D. Hospitals logging crews as they arrive
    Show answer

    Answer: A. Each supervisor tracking assigned people

    In ICS, accountability means every supervisor knows where their assigned people are and what they are doing, backed by check-in and resource tracking. The PIO handles information for the media and the public and does not track personnel. Dispatch helps, but it cannot see who is where on a large scene. Hospitals see only the crews that arrive with patients, long after assignments are made.

15. Several ambulances from a neighboring county arrive at your MCI. Before taking an assignment, NIMS expects them to:

    1. A. Go straight to the patients most in need
    2. B. Set up a separate treatment area of their own
    3. C. Check in so their arrival can be tracked
    4. D. Wait for their own chief to arrive on scene
    Show answer

    Answer: C. Check in so their arrival can be tracked

    Check-in, usually at staging or the command post, lets the IC track every resource and assign it where it is needed. Self-dispatching straight to patients is freelancing, which breaks accountability and can leave key areas uncovered.

16. A responder who goes to work on an incident without an assignment from the incident command structure is:

    1. A. Self-staging
    2. B. Task tracking
    3. C. Field triaging
    4. D. Freelancing
    Show answer

    Answer: D. Freelancing

    Freelancing means acting outside the command structure without an assignment. It undermines accountability, can put the responder in danger, and wastes resources even when the person means well.

17. In ICS, a 'strike team' is a group of:

    1. A. Mixed resources gathered for a single mission
    2. B. Command staff who advise the IC on hazards
    3. C. Off-duty staff on call for a later shift
    4. D. Same-kind, same-type resources under a leader
    Show answer

    Answer: D. Same-kind, same-type resources under a leader

    A strike team is a set number of the same kind and type of resource, such as five ALS ambulances, with a common leader and communications. A mix of resource types under one leader is a task force.

18. Your IC assembles two ambulances, an engine company, and a heavy rescue under one leader to clear a collapsed parking deck. In ICS this is a:

    1. A. Task force
    2. B. Strike team
    3. C. Division
    4. D. Unit
    Show answer

    Answer: A. Task force

    A task force combines different kinds of resources under one leader with common communications for a specific mission. A strike team would be resources of the same kind and type, and a division is a geographic area of the incident.

19. Under NIMS incident complexity typing, a Type 1 incident is one that:

    1. A. Is the smallest, handled by one or two units
    2. B. Involves a hazardous materials release
    3. C. Is most complex and needs national resources
    4. D. Is confined to a single hospital campus
    Show answer

    Answer: C. Is most complex and needs national resources

    NIMS types incidents on a scale from Type 5, the least complex, to Type 1, the most complex. A Type 1 incident needs national-level resources, runs over many operational periods, and fills most ICS positions. The small incident that one or two single resources can handle is Type 5, so that option reverses the scale. Complexity depends on size, resource needs, and duration, not on whether hazardous materials are present. An event confined to one hospital is run under that hospital's own incident command plan; the NIMS type does not depend on location.

20. At a highway pileup spread over 1 mile (1.6 km), the IC creates one unit for the east end and one for the west end. These are best called:

    1. A. Groups
    2. B. Divisions
    3. C. Units
    4. D. Strike teams
    Show answer

    Answer: B. Divisions

    When an incident is divided by location, the parts are divisions. A group is organized by function, such as triage, and may work across both ends. In ICS a unit is a functional element inside a section, such as the triage unit, not a geographic area. A strike team is a set of same-kind resources under one leader, not a part of the scene.

21. Under NIMS resource management, 'resource typing' means:

    1. A. Listing each responder's years of service
    2. B. Grouping resources by capability and kind
    3. C. Tagging each resource with its home agency
    4. D. Assigning resources in the order they arrive
    Show answer

    Answer: B. Grouping resources by capability and kind

    Resource typing describes resources by kind and capability (for example, an ALS versus a BLS ambulance), so a requesting agency gets exactly what it needs. Agency of origin and arrival order do not tell the IC what the resource can do.

22. Current NIMS doctrine (2017) organizes the system into three components: resource management, command and coordination, and:

    1. A. Training, exercise, and evaluation management
    2. B. Planning and response evaluation
    3. C. Communications and information management
    4. D. Mitigation and recovery planning
    Show answer

    Answer: C. Communications and information management

    The 2017 NIMS update groups doctrine into resource management, command and coordination, and communications and information management. Training and exercises support preparedness but are not one of the three components.

23. A county emergency operations center (EOC) is activated during a large MCI. Its main role is to:

    1. A. Support the incident with resources and policy
    2. B. Direct the tactics of the crews working at the scene
    3. C. Replace the incident command post on scene
    4. D. Provide definitive care for injured patients
    Show answer

    Answer: A. Support the incident with resources and policy

    An EOC coordinates resources, information, and policy decisions to support on-scene command. Tactical decisions stay with the incident commander at the command post, so the EOC does not replace or direct field tactics.

24. Two neighboring agencies agree that both will be dispatched together to every crash on their shared highway, without anyone having to ask. This arrangement is called:

    1. A. Unified command
    2. B. Area command
    3. C. Strike team response
    4. D. Automatic aid
    Show answer

    Answer: D. Automatic aid

    Automatic aid sends resources across a jurisdictional line every time a set type of call occurs, under a prior agreement, so no one has to ask. Mutual aid is sent only when the requesting agency asks for it. Unified command is how agencies that share authority run an incident together once they are on scene; it is not a dispatch agreement. Area command oversees several separate incidents. A strike team is a set number of same-kind resources under one leader, not an agreement between agencies.

25. Under NIMS, 'credentialing' of responders refers to:

    1. A. Issuing radio call signs at check-in
    2. B. Recording each responder's work hours
    3. C. Verifying identity and qualifications
    4. D. Giving each crew its own staging area
    Show answer

    Answer: C. Verifying identity and qualifications

    Credentialing confirms that a responder is who they claim to be and is qualified for the assigned role, which matters when outside or volunteer personnel arrive. Recording hours is a finance/administration task.
