When performing CPR on an adult patient, what action should be taken regarding chest compressions?

The recommended action regarding chest compressions when performing CPR on an adult patient is to depress the chest by approximately 5 cm (2 inches) during compressions. This depth is critical for ensuring that the chest compressions are effective in generating adequate blood flow to the heart and brain during cardiac arrest. Compressions that are deep enough can help create the necessary pressure to circulate blood throughout the body, increasing the chances of survival until advanced medical help arrives.

Effective CPR emphasizes the importance of reaching this depth to optimize perfusion. Additionally, proper positioning and rhythm are essential. Aiming for a compression depth of at least 5 cm helps ensure that the heart is adequately compressed and can effectively push blood through the circulatory system.

Other options involve actions that are either not part of current CPR recommendations or are not effective. For instance, checking for a pulse at the radial artery can lead to unnecessary delays in care, as pulse checks can take too long and compromise the effectiveness of CPR. Rescue breaths lasting 3 seconds would not align with guidelines, which recommend a ratio of compressions to breaths and timing that provides stability to the rhythm rather than prolonged breaths. Lastly, the recommended rate of compressions is 100 to 120 compressions per minute, making the stated
