This patient’s vomiting is most likely because of alcohol intoxication. Because vomiting carries a risk of aspiration, the best next step is to maintain the airway and place the patient in side-lying position or raise the head of the bed. After this, the nurse should perform an assessment of emesis characteristics and note if vomiting is projectile. The last steps of management are to assess hydration status, electrolytes, and daily weight, and to notify the doctor.
