1. What is the primary reason ICS requires the use of common terminology among all responding agencies? → To ensure clear communication and mutual understanding among all responders
2. A dispatcher is working a major traffic collision with multiple patients. CAD shows no available ALS units. What should the dispatcher do? → Initiate mutual aid, upgrade the closest BLS unit, and notify a supervisor
3. Why is it important for a dispatcher to remain on the line with a caller during a medical emergency? → To monitor patient status and provide ongoing instructions until responders arrive
4. What is 'triangulation' in qualitative dispatch research? → Comparing findings from multiple data sources or methods to strengthen conclusions
5. In EMD, what is the PRIMARY purpose of interrogation (key questioning) in a medical call? → To determine call priority and guide the appropriate response
6. What does 'inter-rater reliability' measure in dispatch protocol research? → Agreement between two or more independent raters scoring the same data
7. What is 'external validity' in dispatch research? → The degree to which findings can be generalized beyond the study sample
8. In emergency communications, what does 'interoperability' specifically mean? → The ability of different agencies' radio systems to communicate with each other
9. A dispatcher is subpoenaed to testify about a call recording. The dispatcher believes the recording was improperly deleted. What is the appropriate first step? → Immediately notify a supervisor and the agency's legal counsel
10. A dispatcher receives a 911 call but hears only silence after answering. What is the standard protocol? → State the agency name, ask if help is needed, and attempt to trace the location
11. Which level of evidence is considered LOWEST on the evidence hierarchy? → Expert opinion or anecdotal evidence
12. A dispatcher receives a call about a hazardous materials spill at a chemical plant. According to ICS principles, what should be established first? → Command
13. During a multi-casualty incident, a dispatcher receives calls from multiple witnesses reporting the same event. What is the best approach? → Dispatch resources based on the most detailed caller's information
14. Which physical symptom cluster is most commonly reported by dispatchers experiencing occupational burnout? → Chronic fatigue, sleep disturbances, and frequent headaches
15. What is a key principle of multi-agency coordination in Certified Emergency Dispatcher practice? → Applying structured methodologies based on evidence and best practices
16. An off-duty officer calls in to report a situation and wants to handle it without official dispatch. The dispatcher should: → Document the call and dispatch appropriate resources per standard protocol
17. Why is evidence-based practice important in Certified Emergency Dispatcher? → It integrates best available evidence with expertise for improved outcomes
18. A caller describes a suicidal subject who has barricaded themselves inside a home with a firearm. Which units should be dispatched? → Police, EMS, and a crisis negotiation team
19. A dispatcher receives a duplicate call for the same address already in the CAD. What should the dispatcher do first? → Link the new call to the existing incident
20. A caller provides information that conflicts with what a bystander is shouting in the background. How should the dispatcher handle this? → Acknowledge both information sources and clarify discrepancies with targeted questions
21. Under ICS, what role is responsible for coordinating communication between agencies at the operations level during a major incident? → Liaison Officer
22. Which type of incident most commonly triggers the activation of formal CISD in an emergency dispatch center? → Line-of-duty death, mass casualty event, or the death of a child caller
23. When establishing communications during a multi-agency response, which of the following should dispatchers confirm FIRST? → That a common operating frequency or channel has been established
24. In a dispatch quality improvement study, 'process measures' refer to: → Actions taken during the dispatch process itself
25. What is a corrective action in Certified Emergency Dispatcher quality systems? → A systematic response to eliminate causes of nonconformity and prevent recurrence
26. A dispatcher is monitoring a channel and hears a unit transmit 'Code 4, no further assistance needed.' This communication indicates: → The situation is under control and additional resources are not required
27. In radio communications, what does 'radio dead zone' or 'shadow' refer to? → A geographic area where radio signals cannot reliably reach due to terrain or structures
28. Which approach best demonstrates professional competency in CED practice? → Integrating education, experience, and evidence-based decision making
29. What is one key consideration in making decisions during a crisis? → The urgency and potential impact of the decision
30. A hearing-impaired caller contacts the center via TTY/TDD. What is the dispatcher's obligation? → Respond using proper TTY protocols and maintain the connection
