The correct answer is B) establish an open airway. Before administering CPR, it is crucial to ensure the victim has an open airway. This is the first and most important step in the CPR protocol, as the victim needs to be able to receive oxygen in order for CPR to be effective. Establishing an open airway involves tilting the victim's head back and lifting the chin to clear any obstructions and allow air to flow freely. The other answer choices are incorrect because they do not address the immediate need to establish an open airway. Making the victim comfortable, treating bleeding wounds, or ensuring the victim is conscious are important steps, but they should only be done after the airway has been cleared and CPR is ready to begin.
