Final answer:
When performing CPR on an unresponsive choking victim, it is important to 3) administer rescue breaths before chest compressions.
Step-by-step explanation:
When performing CPR on an unresponsive choking victim, it is important to follow the correct steps to clear the airway and provide life-saving care. The correct option among the given choices is 3) Administer rescue breaths before chest compressions.
Before starting CPR, it is important to ensure the victim's airway is clear. In the case of a choking victim who is unresponsive, the rescuer should attempt to clear the airway by administering rescue breaths. This involves giving two slow breaths into the victim's mouth while ensuring an airtight seal.
After administering the rescue breaths, the rescuer should then proceed with chest compressions. This involves positioning the hands on the sternum, between the lines at T4 and T9, and applying pressure to compress the chest at a rate of 100 compressions per minute.
It is important to note that checking for a pulse is not recommended before starting CPR. In an emergency situation, it is best to assume the victim does not have a pulse and immediately start CPR. Therefore the correct answer is 3) administer rescue breaths before chest compressions.
