Transport, Triage, Communication, Documentation, Medical
Direction, Disaster Response, Legal and Ethical Responsibilities,
Quality Improvement & Emergency Decision-Making
Question 1
Which of the following best describes the primary purpose of an EMS system's "medical
director"?
A. To manage the daily scheduling and deployment of all EMS units.
B. To provide legal representation for the EMS agency in cases of malpractice.
C. To assume ultimate responsibility for the clinical care provided by the EMS system.
D. To oversee the financial budget and purchasing of all medical equipment.
Correct Answer: C
Explanation: The medical director is a physician who legally and ethically assumes ultimate
responsibility for all clinical aspects of the EMS system, including protocols and quality
assurance.
Question 2
An EMS crew is dispatched to a multi-vehicle collision on a busy highway. Upon arrival, the
paramedic's first priority is to:
,A. Begin triaging the most critically injured patients.
B. Establish command and ensure scene safety for all responders.
C. Quickly extricate a patient from a smoking vehicle.
D. Request additional resources and law enforcement backup.
Correct Answer: B
Explanation: Scene safety and establishing command are the absolute first priorities at any
incident to prevent further injury to responders, patients, and bystanders.
Question 3
A 55-year-old male with a history of hypertension presents with a sudden, severe headache
and a blood pressure of 220/120 mmHg. He is conscious but confused. Which of the
following is the most appropriate destination for this patient?
A. The nearest hospital, regardless of its capabilities.
B. A hospital with a dedicated stroke center.
C. A hospital with a specialized cardiac catheterization lab.
D. A Level I trauma center.
Correct Answer: B
Explanation: The patient's presentation is highly suggestive of a hypertensive emergency,
likely a hemorrhagic stroke. Transport to a stroke center is critical for rapid neurological
assessment and intervention.
Question 4
,During a Mass Casualty Incident (MCI), the START triage system is being used. A patient who
is ambulatory and has minor injuries would be assigned which triage color?
A. Red
B. Yellow
C. Green
D. Black
Correct Answer: C
Explanation: In the START triage system, the "Green" category is for the "walking wounded"
or patients with minor injuries who can wait for treatment and transport.
Question 5
Which of the following is the most reliable method for confirming endotracheal tube
placement in an adult patient?
A. Auscultating for equal breath sounds bilaterally.
B. Observing chest rise and fall.
C. Using a colorimetric end-tidal CO2 detector.
D. Hearing air escaping from the tube during compressions.
Correct Answer: C
Explanation: Continuous waveform capnography is the gold standard, but a colorimetric end-
tidal CO2 detector is a highly reliable and practical field method to confirm tracheal
placement.
, Question 6
An EMS supervisor is conducting a quality improvement review of a cardiac arrest
resuscitation. The review finds that the fraction of time the patient received chest
compressions (chest compression fraction) was 45%. What is the primary implication of this
finding?
A. The team was over-ventilating the patient.
B. The team was not defibrillating quickly enough.
C. The team had excessive interruptions in compressions, reducing coronary perfusion.
D. The team was using an incorrect compression rate.
Correct Answer: C
Explanation: A low chest compression fraction indicates frequent or long interruptions in
compressions, which lowers coronary perfusion pressure and reduces the chance of return
of spontaneous circulation (ROSC).
Question 7
A patient with a suspected cervical spine injury needs to be extricated from a vehicle. Which
technique is preferred to minimize spinal movement?
A. Rapid extrication by pulling the patient under the arms.
B. Application of a cervical collar, then a rapid take-down.
C. Use of a short spine board or vest-type extrication device.
D. Allowing the patient to self-extricate if they are able.
Correct Answer: C
