JIBC Emergency Medical Responder Care 4 — Questions and Answers
Question 1: When should an EMR consider stopping CPR in the field?
- After 10 minutes of CPR without ROSC
- When the scene becomes unsafe, valid DNR is confirmed, or EMS assumes care (Correct answer)
- When the patient's skin becomes mottled
- After the AED has delivered three shocks without response
Correct answer: When the scene becomes unsafe, valid DNR is confirmed, or EMS assumes care
An EMR may stop CPR when the scene becomes dangerous, a valid DNR is presented, or higher-level EMS providers take over care.
Question 2: A patient with a diabetic emergency is confused but can still swallow. The EMR should:
- Administer oral glucose gel between the cheek and gum (Correct answer)
- Withhold all glucose until blood sugar is confirmed low by glucometer
- Position the patient supine and monitor only
- Give water to dilute blood sugar
Correct answer: Administer oral glucose gel between the cheek and gum
If a diabetic patient is conscious and can protect their airway, oral glucose gel can be safely administered to address hypoglycemia.
Question 3: The 'rule of nines' is used to estimate:
- Degree of burn depth
- Total body surface area affected by burns (Correct answer)
- Fluid replacement volume for burns
- Pain severity in burn patients
Correct answer: Total body surface area affected by burns
The rule of nines divides the body into sections each representing approximately 9% to estimate total body surface area (TBSA) burned.
Question 4: A patient presents with a sucking chest wound. The EMR should immediately:
- Apply a fully occlusive dressing on all four sides
- Apply a vented (three-sided) chest seal or improvised flutter valve (Correct answer)
- Firmly pack the wound with gauze
- Position the patient prone to seal the wound
Correct answer: Apply a vented (three-sided) chest seal or improvised flutter valve
A three-sided or vented chest seal allows air to escape on exhalation while preventing air entry, reducing the risk of tension pneumothorax.
Question 5: Which of the following pulse oximetry readings in an adult at rest indicates a need for supplemental oxygen?
- SpO2 of 98%
- SpO2 of 95%
- SpO2 of 93%
- SpO2 of 88% (Correct answer)
Correct answer: SpO2 of 88%
An SpO2 below 90–94% (depending on protocol) indicates hypoxemia requiring supplemental oxygen in most emergency care settings.
Question 6: The term 'mechanism of injury' (MOI) refers to:
- The anatomical location of the patient's injury
- The forces and events that caused the patient's trauma (Correct answer)
- The severity classification of a traumatic injury
- The medical history related to the injury
Correct answer: The forces and events that caused the patient's trauma
Mechanism of injury describes the forces (kinetic energy, type of impact) and events that produced a traumatic injury.
Question 7: When immobilizing a suspected femur fracture, the EMR should:
- Straighten the leg forcibly before splinting
- Splint the limb in the position found and include joints above and below the fracture (Correct answer)
- Apply a tourniquet immediately above the fracture site
- Avoid all movement until EMS arrives
Correct answer: Splint the limb in the position found and include joints above and below the fracture
Splinting in the position found and immobilizing joints above and below the fracture minimizes further injury and pain.
