First Aid, CPR, and Emergency Response

What this domain tests

First Aid, CPR, and Emergency Response tests scene safety, basic life support, bleeding control, and the legal protection for good-faith aid.

Core rules

  • Scene safety first. Do not become a second patient. Use gloves, eye protection, and a barrier device.
  • CPR. For an adult, compress at 100–120 per minute, depth 2–2.4 inches, full recoil, 30 compressions to 2 breaths. Use an AED as soon as available.
  • Severe bleeding. Apply direct pressure, then a tourniquet high and tight on the limb if pressure fails; note the time.
  • Opioid overdose. Give naloxone, support breathing, and place the person in a recovery position if breathing.
  • Good Samaritan. ORC 2305.23 protects a person who renders emergency care without expectation of compensation, absent willful or wanton misconduct.

Worked example

An officer finds a man unresponsive with pinpoint pupils and slow breathing beside a syringe. The officer puts on gloves, confirms the scene is safe, gives naloxone, and begins rescue breathing. The man begins breathing; the officer places him on his side and monitors until EMS arrives. Reasoning: the presentation suggests opioid overdose; naloxone is indicated, but airway support is the priority. The recovery position protects the airway. Document the dose and time.

Traps

  • Rushing in without checking for hazards.
  • Delaying compressions to find a pulse in a witnessed collapse.
  • Putting a tourniquet on a joint or too loosely.
  • Moving a trauma patient unnecessarily.
