Which statement about chest compression depth in CPR is true according to the guidelines?

Explanation:
When performing CPR on an adult, the goal of chest compressions is to generate enough blood flow by creating sufficient pressure with each squeeze. The guidelines specify a depth of at least 2 inches (about 5 cm) for each compression, with full chest recoil between compressions. This depth reliably moves blood out of the heart without unduly increasing injury risk. A depth of 1 inch is too shallow to produce adequate circulation. Going deeper than about 2.4–2.5 inches can raise the chance of injury without providing proportional benefit, so the standard target reflected in the guidelines is 2 inches.
