🔍 Key Concepts

• Standard CPR sequence for an unresponsive victim (airway, breathing, circulation) • How electric shock affects both breathing and heart function • Proper hand placement and body posture when doing closed chest cardiac massage

💭 Think About

• Think about whether closed chest cardiac massage alone is usually enough, or whether it is normally combined with another life‑support action. • Consider which options describe positioning and technique versus which option changes the overall CPR procedure. • Ask yourself what the current basic life support guidance says you must do if the victim is not breathing and has no pulse.

✅ Before You Answer

• Verify what standard CPR for adults requires when there is no breathing and no pulse (chest compressions alone vs. compressions plus ventilations). • Check which answer choice, if followed, would omit a critical life‑support step rather than just describe how to position or move your body. • Confirm that all recommended steps maintain an open airway and oxygen supply, not just blood circulation.
