EMR First Responder 3 — Questions and Answers
Question 1: Which of the following BEST describes the EMR's role at a multi-casualty incident (MCI)?
- Treat the most critically injured patient first regardless of resources
- Perform primary triage and begin immediate life-saving interventions (Correct answer)
- Wait for ALS units before touching any patient
- Evacuate all patients to the nearest hospital immediately
Correct answer: Perform primary triage and begin immediate life-saving interventions
At an MCI, the EMR performs triage and initiates life-saving interventions, maximizing the number of survivors with available resources.
Question 2: A diabetic patient is confused, diaphoretic, and has a blood glucose reading of 48 mg/dL. The patient can swallow. The EMR should:
- Administer insulin as ordered
- Give oral glucose gel or sugar (Correct answer)
- Place the patient supine and monitor
- Start IV fluid therapy
Correct answer: Give oral glucose gel or sugar
A conscious patient with hypoglycemia who can swallow should receive oral glucose to rapidly raise blood sugar.
Question 3: The START triage system classifies patients based on all of the following EXCEPT:
- Respiratory rate
- Radial pulse presence
- Glasgow Coma Scale score (Correct answer)
- Ability to walk
Correct answer: Glasgow Coma Scale score
START triage uses respirations, perfusion (radial pulse/capillary refill), and mental status — not the full GCS score.
Question 4: An EMR is treating a patient in anaphylactic shock. The patient has their own epinephrine auto-injector. After assisting with administration, which site is correct?
- Deltoid muscle of the upper arm
- Outer mid-thigh (Correct answer)
- Anterior forearm
- Lateral abdomen
Correct answer: Outer mid-thigh
Epinephrine auto-injectors are designed for injection into the outer mid-thigh for reliable absorption.
Question 5: When sizing a rigid cervical collar for a trauma patient, the measurement is taken from:
- Chin to the top of the sternum (Correct answer)
- Chin to the shoulder
- Earlobe to the shoulder
- Mastoid to the clavicle
Correct answer: Chin to the top of the sternum
Cervical collar size is determined by measuring from the bottom of the chin to the top of the sternum (or trapezius).
Question 6: A patient has a burn covering the entire front of both legs. Using the Rule of Nines, what percentage of body surface area (BSA) is burned?
- 9%
- 18% (Correct answer)
- 27%
- 36%
Correct answer: 18%
Each full leg equals 18% BSA; the front of each leg is 9%, so both anterior legs total 18% BSA.
Question 7: Which finding BEST indicates that a patient has adequate perfusion?
- Respiratory rate of 22 breaths/min
- Radial pulse present and skin warm and dry (Correct answer)
- Blood pressure of 90/60 mmHg
- GCS score of 13
Correct answer: Radial pulse present and skin warm and dry
A palpable radial pulse with warm, dry skin indicates adequate peripheral perfusion.
