Correct answer: C. About 5 to 6 centimetres
- A. About 2 to 3 centimetres
- B. About 3 to 4 centimetres
- C. About 5 to 6 centimetres
- D. About 7 to 8 centimetres
Explanation
Adult compressions should depress the chest about 5 to 6 centimetres, allowing full recoil after each compression. Shallower compressions may produce inadequate circulation, while excessive depth can cause injury.
