Karen is bulimic, a condition where she induces vomiting to avoid weight gain. When the doctor sees her, her weight is 89 pounds and her respiratory rate is 6 breaths/min.  (Normal = 12/min.).

Her PCO 2 is 61 mm Hg (normal = 40mm).
Why is she hypoventilating?
A) Her PCO 2 is high, and the body monitors PCO 2 to control ventilation.
B) Her O 2 must be low, because the body monitors O 2 to control ventilation.
