Review Question - QID 212870

An 11-year-old boy is brought to the emergency department by his mom with an 8-hour history of vomiting and abdominal pain. He has no past medical history but recently has been eating more than usual, which his mom attributes to a growth spurt. On presentation, his temperature is 98.9°F (37.1°C), blood pressure is 104/61 mmHg, pulse is 117/min, and respirations are 30/min. Physical exam reveals a thin and ill-appearing boy who is breathing very deeply. He responds lethargically to questions and is sometimes hard to arouse. Which of the serum lab results shown in Figure A would most likely be seen in this patient?
