The following are multiple choice questions (with answers) about medical knowledge.   **Question:** A 3-year-old boy is brought to the emergency room by his mother after she found him somnolent at home next to multiple open pill bottles. The boy had seemingly opened several different pill bottles that were in a cabinet in his parent’s bathroom. The mother has brought the empty bottles to the emergency room, and they include aspirin, metoprolol, acetaminophen, levothyroxine, and lorazepam. The boy has no past medical history and takes no medications. His temperature is 98.6°F (37°C), blood pressure is 110/65 mmHg, pulse is 85/min, and respirations are 28/min. On exam, the boy is lethargic but responsive. He appears to be grasping at his ears and swaying from side-to-side when attempting to ambulate. He vomited once in the emergency room. Which of the following arterial blood gas readings is most likely to be found in this patient?   (A) pH 7.29, PCO2 47 mmHg, and HCO3- 22 mEq/L   (B) pH 7.35, PCO2 29 mmHg, and HCO3- 15 mEq/L   (C) pH 7.36, PCO2 22 mmHg, and HCO3- 16 mEq/L   (D) pH 7.47, PCO2 41 mmHg, and HCO3- 29 mEq/L
