Question

b. At least 2 inches but no more than 2.4 inches
c. About 1½ inches
d. At least 1 inch but no more than 2 inches

Answer 1

When performing CPR on an adult, chest compressions should be at least 2 inches but no more than 2.4 inches deep.

Step-by-step explanation:

When performing CPR on an adult, chest compressions should be at least 2 inches but no more than 2.4 inches deep. Current standards recommend compressing the chest to a depth of at least 5 cm, which is equivalent to about 2 inches. Deep compressions help to circulate the blood and provide effective chest compressions for the patient.
