Lungs Breathing Difficulty and blood gas analysis

A 14-year-old girl is brought by her father to the emergency room (ER) with a complaint of shortness of breath. Her symptom began 1 hour ago. She has suffered several of these episodes of breathing difficulty in the past, and her vital signs and physical exam are entirely consistent with her most likely diagnosis. Included in her diagnostic workup is an arterial blood gas (ABG). Results from the ABG include: PaO2 = 75 mm Hg, PaCO2 = 59 mm Hg, and HCO3- = 30 mEq/L. Which lab finding would be expected based on the child's likely acute clinical condition?
A) Decreased anion gap
B) Hypernatremia
C) Increased serum haptoglobin levels
D) Low hematocrit
E) Oxyhemoglobin dissociation curve is shifted to the right
