NWSA Emergency Response and First Aid 1 — Questions and Answers
Question 1: When arriving at a tower site where a worker has been found unresponsive, the very first action must be to:
- Begin chest compressions immediately
- Ensure the scene is safe before approaching the victim (Correct answer)
- Call the site supervisor before doing anything
- Remove the victim's hard hat and check for head injuries
Correct answer: Ensure the scene is safe before approaching the victim
Scene safety must be confirmed before any rescuer approaches an unresponsive victim to avoid creating additional casualties from the same hazard.
Question 2: Current American Heart Association (AHA) guidelines recommend a CPR chest compression rate of:
- 60 compressions per minute
- 80 compressions per minute
- 100–120 compressions per minute (Correct answer)
- 150 compressions per minute
Correct answer: 100–120 compressions per minute
The AHA recommends a compression rate of 100–120 per minute to generate adequate blood flow during cardiac arrest.
Question 3: The correct compression-to-ventilation ratio for single-rescuer adult CPR is:
- 15:2
- 5:1
- 10:1
- 30:2 (Correct answer)
Correct answer: 30:2
For adult CPR with one rescuer, the AHA standard is 30 chest compressions followed by 2 rescue breaths, repeated continuously.
Question 4: An AED (Automated External Defibrillator) is specifically designed to treat:
- Ventricular fibrillation and pulseless ventricular tachycardia (Correct answer)
- Respiratory arrest with absent pulse
- Anaphylactic shock reactions
- Traumatic injuries causing blood loss
Correct answer: Ventricular fibrillation and pulseless ventricular tachycardia
AEDs deliver a controlled electrical shock to reset shockable cardiac rhythms — specifically ventricular fibrillation and pulseless ventricular tachycardia.
Question 5: OSHA requires that first aid kits on construction job sites be:
- Locked and accessible only through the site supervisor
- Readily accessible to all workers at all times (Correct answer)
- Stored exclusively in the main office trailer
- Inspected only quarterly by the designated safety officer
Correct answer: Readily accessible to all workers at all times
OSHA mandates that first aid supplies be immediately accessible to every worker so care can be administered without delay after an injury.
Question 6: A worker who has been suspended in a fall arrest harness and rescued must:
- Return to light duty after a 10-minute rest break
- Complete an incident report and continue working the shift
- Be evaluated by medical personnel before returning to work (Correct answer)
- Drink water and self-monitor for 30 minutes
Correct answer: Be evaluated by medical personnel before returning to work
Harness suspension can cause suspension trauma (orthostatic intolerance) with delayed onset; medical evaluation is mandatory before the worker resumes any duties.
