Pupils are 6 mm and poorly reactive to light. Mucous membranes are dry. Her airway is patent and her pulmonary examination is unremarkable. Her abdomen is soft, mildly distended, and bowel sounds are absent. She is placed on 2L of 100% O2 by nasal cannula, and a normal saline IV bolus is initiated. Serum glucose is 85, and other laboratory studies are pending. Electrocardiogram reveals sinus tachycardia and QRS duration of 130 msec. What is the next best step in management?
