The correct hand position for chest compressions in CPR for an adult or child is

• A. On the lower half of the breastbone midway between nipples
• B. On the left side of the chest
• C. On the upper sternum
• D. On the xiphoid process

Answer: (A)

The hands should be placed on the center of the chest, on the lower half of the sternum (breastbone), midway between the nipples. This position lines up with the heart, which sits behind the sternum, so pressing here pushes the heart straight toward the spine and generates the best blood flow during compressions. Placing the hands to the left of center or on the upper part of the sternum misses the heart, making compressions less effective. Pressing on the lower tip, or xiphoid process, can cause injury to the chest wall or internal organs. So the midline, lower-half sternum location is the safest and most effective site for both adults and children.
