When performing CPR on an adult, it is crucial to ensure that chest compressions are both effective and safe. Here is the comprehensive step-by-step solution to determine the correct depth and rate of compressions per minute:

1. Depth of Compressions:
- According to the guidelines, the chest must be compressed to a depth of 2 to 2.4 inches. This depth ensures that adequate blood flow is generated to vital organs during the compression phase of CPR.
- Converting these measurements to the metric system, 2 inches equates to approximately 5 centimeters, and 2.4 inches equates to approximately 6 centimeters.
- Hence, the appropriate depth for chest compressions is 2 to 2.4 inches or 5 to 6 centimeters.

2. Rate of Compressions:
- The recommended rate for chest compressions during CPR is 100 to 120 compressions per minute. This rate has been determined to maximize blood flow without causing excessive fatigue for the person performing CPR.

Based on these guidelines, the correct answer to the question, "When performing CPR on an adult, you should compress the chest to what depth and at what rate of compressions per minute?" is:

2 to 2.4 inches (5 to 6 cm); 100 to 120
