Which step is NOT part of performing CPR?

Providing dietary advice is not part of the CPR protocol. CPR, or cardiopulmonary resuscitation, is a lifesaving technique used in emergencies when someone's heartbeat or breathing has stopped. The primary steps involved in CPR include checking for responsiveness, calling for help, and initiating chest compressions to maintain blood flow to vital organs until professional help arrives.

Checking for responsiveness ensures that the person needs assistance, while calling for help prompts emergency services to take action. Initiating chest compressions is critical as it helps circulate blood and oxygen throughout the body. Dietary advice, however, falls outside the context of immediate life-saving measures required during a cardiac emergency and is not a consideration during the CPR process.
