Paramedics Exam Rescue Operations 2 — Questions and Answers
Question 1: When approaching a vehicle collision scene at night, where should the rescue unit be positioned?
- Directly behind the crashed vehicle
- Uphill and upwind from the scene
- At an angle to the scene with lights illuminating the wreckage (Correct answer)
- Parallel to the road to block one lane
Correct answer: At an angle to the scene with lights illuminating the wreckage
Positioning the unit at an angle with lights aimed at the wreckage maximizes scene visibility while protecting rescuers from traffic.
Question 2: What is the PRIMARY hazard when performing rescue operations near downed electrical lines?
- Fire ignition from sparks
- Step potential voltage traveling through the ground (Correct answer)
- Direct contact with the wire only
- Electromagnetic interference with medical equipment
Correct answer: Step potential voltage traveling through the ground
Step potential (ground gradient) allows current to flow through a rescuer's body if their feet are at different voltages on energized ground.
Question 3: During a confined-space rescue, atmospheric monitoring detects 18% oxygen. The correct action is:
- Enter with SCBA and proceed with rescue
- Ventilate the space for 5 minutes then re-enter
- Declare an IDLH atmosphere and do not enter without proper PPE (Correct answer)
- Send one rescuer with an air-purifying respirator
Correct answer: Declare an IDLH atmosphere and do not enter without proper PPE
Oxygen levels below 19.5% define an IDLH (Immediately Dangerous to Life or Health) atmosphere requiring supplied-air entry only.
Question 4: The 'golden hour' concept in trauma is MOST relevant to which rescue scenario?
- Confined-space entrapment requiring extrication (Correct answer)
- Structural collapse with patients ambulatory
- Water rescue in a heated pool
- Patients in a motor vehicle crash with minor injuries
Correct answer: Confined-space entrapment requiring extrication
Prolonged entrapment delays definitive surgical care, making rapid extrication critical to survival within the golden hour.
Question 5: A patient is pinned under a vehicle with suspected crush syndrome. EMS should anticipate which complication upon extrication?
- Sudden hyperglycemia
- Reperfusion-induced hyperkalemia and cardiac dysrhythmia (Correct answer)
- Acute hypertensive crisis
- Immediate coagulopathy requiring blood transfusion
Correct answer: Reperfusion-induced hyperkalemia and cardiac dysrhythmia
Releasing prolonged compression allows myoglobin and potassium to flood the circulation, risking fatal cardiac dysrhythmias.
Question 6: Which rope rescue system provides the greatest mechanical advantage for raising a litter?
- 2:1 system
- 3:1 (Z-rig) system
- 4:1 system
- 6:1 (C-rig) system (Correct answer)
Correct answer: 6:1 (C-rig) system
A 6:1 (C-rig) system provides six times the input force, making it the most efficient for raising heavy loads in technical rescue.
Question 7: During water rescue, a non-swimming bystander is trying to reach a drowning victim. The paramedic should FIRST:
- Allow the bystander to attempt rescue while preparing equipment
- Direct the bystander to throw a rope or flotation device rather than enter the water (Correct answer)
- Have the bystander wade in waist-deep to extend reach
- Call for a boat before taking any other action
Correct answer: Direct the bystander to throw a rope or flotation device rather than enter the water
Reach-throw-row-go prioritization keeps rescuers safe; a panicking drowning victim can incapacitate an untrained swimmer.
