Which is the correct sequence for performing chest compressions and ventilations for an adult in CPR?

15 compressions followed by 2 ventilations
30 compressions followed by 2 ventilations
30 compressions followed by 4 ventilations
40 compressions followed by 2 ventilations

The correct answer is: 30 compressions followed by 2 ventilations

Performing 30 compressions followed by 2 ventilations is the correct sequence for performing CPR on an adult. This follows the standard 302 compression to ventilation ratio recommended by the American Heart Association. Option A, 15 compressions followed by 2 ventilations, does not provide enough compressions per minute and may not effectively circulate blood. Option C, 30 compressions followed by 4 ventilations, provides too many ventilations and does not allow for enough compressions to be performed. Option D, 40 compressions followed by 2 ventilations, also does not follow the recommended ratio and may result in inadequate ventilation for the patient.
