Chauffeur License Emergency Response & First Aid 3 — Questions and Answers
Question 1: A passenger complains of sudden crushing chest pain radiating to the left arm. What condition should you suspect?
- Heart attack (myocardial infarction) (Correct answer)
- Muscle cramp from prolonged sitting
- Panic attack
- Acid reflux
Correct answer: Heart attack (myocardial infarction)
Crushing chest pain radiating to the left arm is a classic symptom of a heart attack and requires immediate emergency response.
Question 2: If a passenger is unresponsive and not breathing normally, and you are alone, what is the correct order of actions?
- Call 911, then begin CPR (Correct answer)
- Begin CPR for 2 minutes, then call 911
- Check for a pulse for 60 seconds before calling 911
- Wait for another passenger to call 911 while you continue driving
Correct answer: Call 911, then begin CPR
Call 911 first so advanced help is dispatched, then immediately begin CPR to maintain circulation.
Question 3: During CPR on an adult, what is the recommended compression-to-breath ratio for a single rescuer?
- 30 compressions to 2 breaths (Correct answer)
- 15 compressions to 2 breaths
- 5 compressions to 1 breath
- 20 compressions to 1 breath
Correct answer: 30 compressions to 2 breaths
The American Heart Association recommends a 30:2 ratio of chest compressions to rescue breaths for single-rescuer adult CPR.
Question 4: A passenger suddenly faints in your vehicle. After ensuring the scene is safe, what should you do first?
- Check for responsiveness by tapping their shoulders and calling out (Correct answer)
- Splash cold water on their face immediately
- Loosen their clothing and recline the seat
- Give them smelling salts from the first aid kit
Correct answer: Check for responsiveness by tapping their shoulders and calling out
Checking for responsiveness is the first step in assessing an unconscious person before proceeding with further aid.
Question 5: What is the recommended depth for chest compressions when performing CPR on an adult?
- At least 2 inches (5 cm) (Correct answer)
- 1 inch (2.5 cm)
- 3 to 4 inches (7–10 cm)
- Half an inch (1.3 cm)
Correct answer: At least 2 inches (5 cm)
The AHA recommends compressing the chest at least 2 inches (5 cm) but not more than 2.4 inches for effective CPR on adults.
Question 6: A passenger is burned by a hot beverage spill. Which immediate first aid step is correct?
- Cool the burn with cool (not ice cold) running water for 10–20 minutes (Correct answer)
- Apply butter or oil to soothe the burned area
- Cover the burn tightly with plastic wrap immediately
- Pop any blisters that form to prevent infection
Correct answer: Cool the burn with cool (not ice cold) running water for 10–20 minutes
Cool running water for 10–20 minutes is the recommended first aid for a burn; ice, butter, and popping blisters can worsen the injury.
Question 7: Which type of fire extinguisher is appropriate for a vehicle electrical fire?
- Class C or ABC dry chemical extinguisher (Correct answer)
- Class A water-based extinguisher
- Class B foam extinguisher only
- Any extinguisher available since all types work on vehicle fires
Correct answer: Class C or ABC dry chemical extinguisher
Class C or ABC extinguishers are rated for electrical fires; using water on an electrical fire can cause electrocution.
