A 13-year-old presents to the emergency department. His parents state that he
passed out at home and had been vomiting and had diarrhea for the last few days.
He answers questions appropriately, although he complains of dizziness. His vital
signs on arrival: BP 70/40 mm Hg, HR 132 beats/min, RR 24 breaths/min, T 36.9
C (98.4 F), and SpO2 97% without supplemental oxygen. A new graduate nurse
inserted an intravenous line and is about to begin a fluid bolus of D5W. What does
