🔍 Key Concepts

• Proper hand placement for adult CPR per current first aid/CPR guidelines • The structure and location of the sternum (breastbone) • Risks of pressing on the xiphoid process (tip of the sternum) or directly over the heart on one side

💭 Think About

• Think about which area of the chest can safely transmit force to the heart without damaging ribs or internal organs. • Which part of the sternum is broad, flat, and centrally located, and which part is narrow or pointed? • Why is it important to avoid pressing on the very bottom tip of the breastbone or off to the left side?

✅ Before You Answer

• Identify which option describes a central, flat area of the breastbone, not off to one side. • Eliminate any option that involves pressing on the xiphoid process (the pointed tip) of the sternum. • Confirm that the chosen area allows compressions to be delivered on the center of the chest, not just over the left chest where the heart lies.
