What is the correct sequence of actions after opening the airway for mouth-to-mouth ventilation on an adult?

• A. Pinch the nose and seal your lips around the victim's mouth; Give 1 breath and blow for about 1 second; Watch for chest rise; Give a second breath
• B. Seal lips around mouth first; Pinch nose; Give two breaths; Check pulse
• C. Give a second breath immediately; Pinch nose; Seal lips; Check pulse
• D. Check pulse first; Then give breaths

Answer: (A)

Opening the airway and starting mouth-to-mouth ventilation for an adult relies on an airtight seal and delivering breaths that actually inflate the lungs. Pinch the victim’s nose and seal your lips over their mouth, then give a breath for about one second and watch for chest rise. If the chest rises, give a second breath in the same way. This two-breath sequence ensures the lungs are being filled and that the breaths are of appropriate duration. If the chest does not rise on the first attempt, reposition the head and try again with a proper seal. Other sequences either place a pulse check before ventilations or mix up the order, which can delay or prevent effective air entry.
