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 blood HCO 3 - is 62 meq/L (normal 24-29). Her arterial blood pH is 7.61 (normal = 7.4) 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. C) Her blood pH is basic, and the body monitors pH to control ventilation. D) Her blood bicarbonate is high, and the body monitors HCO3- to control ventilation.

Question
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 blood HCO 3 - is 62 meq/L (normal 24-29).
Her arterial blood pH is 7.61 (normal = 7.4)
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.
C) Her blood pH is basic, and the body monitors pH to control ventilation.
