You are supervising a college party. One guest is semi-responsive, vomiting, and has shallow breathing. Using the continuum concept of BAC effects, which integrated plan best synthesizes immediate priorities?

Treat this as a medical emergency: call emergency services immediately, ensure airway protection (position on the side if breathing), stop further alcohol intake, and provide information to responders—because symptoms suggest serious CNS depression on the continuum that can progress rapidly to respiratory failure.

Give them acetaminophen to treat any pain or headache and keep them upright to prevent aspiration; call a friend to drive them home once they regain responsiveness, as immediate medical services are unnecessary unless unconscious.

Allow the guest to sleep it off in a quiet room after giving them water and a small snack, then re-evaluate in a few hours—because most alcohol effects are benign and resolve with rest alone.

Induce vomiting to clear alcohol from the stomach and give them coffee to improve alertness, then allow them to continue socializing under observation since stimulating them reduces BAC quickly.
