🔍 Key Concepts

• Proper mouth-to-mouth technique to create an airtight seal • Role of the nose and mouth in air leakage during rescue breathing • Which actions actually block or close gaps where air could escape

💭 Think About

• Think about where air could leak out of the victim’s airway if you only pinch the nose—what still needs to be sealed? • Which option directly involves contact between the rescuer’s and victim’s mouths, rather than just hand position or head position? • Which choice is specifically about making a tight closure, not just supporting or positioning the head or jaw?

✅ Before You Answer

• Identify which option most clearly prevents air from escaping around the mouth area • Eliminate any choices that are mainly about positioning (head or jaw) rather than sealing • Confirm that the remaining option would create a direct, tight seal between rescuer and victim
