Safety and First Aid: Prevention, Response, and Prioritization
Core concepts
Safety questions test both prevention (removing hazards) and response (correct first aid sequence). Know the emergency action steps: ensure the scene is safe, check responsiveness and breathing, activate emergency services, and provide care within your training. Understand universal precautions - gloves, hand hygiene, and barriers to prevent bloodborne exposure.
Know key first aid priorities. For severe bleeding, apply direct pressure with a clean barrier. For burns, cool with running water, do not apply ice or break blisters. For choking in a conscious adult, use abdominal thrusts; for an unresponsive victim, begin CPR and activate EMS. For CPR, high-quality compressions are deep and fast with minimal interruptions; know that an AED analyzes rhythm and delivers a shock and should be used as soon as available. For seizures, protect the person from injury, do not restrain or place anything in the mouth, and time the event. For poisoning, contact poison control and do not induce vomiting unless instructed.
Understand injury prevention: seat belts, helmets, smoke detectors, water safety, safe storage of medications and firearms, and fall prevention. Recognize signs of concussion (headache, confusion, dizziness, nausea) and that the person should stop activity and be evaluated.
Traps
Questions offer unsafe folk remedies (butter on burns, ice on burns, inducing vomiting). Another trap reverses the priority order - scene safety always comes first, even before helping the victim. Watch for answers that suggest moving an injured person unnecessarily.
Worked example / rule of thumb
Rule of thumb: Safety → Response → Breathing → Care. Example: you find a person collapsed near a downed power line. Do not approach; call for help from a safe distance and keep others back. Only after the scene is safe do you check responsiveness and breathing.
Exam strategy
Eliminate any answer that puts the rescuer at risk or delays activation of emergency services.
