Quizplus · Accepted Answer

Hypercapnia refers to excessive levels of CO₂ in the arterial blood. It is seen with many pulmonary diseases and may be caused by hypoventilation, which leads to inadequate elimination of CO₂. The statement that does not describe hypercapnia is D, which is the opposite of what actually happens in hypercapnia. Hypercapnia occurs when CO₂ production by the tissues exceeds the rate at which it can be eliminated from the body.
