Question

Quizplus · Accepted Answer

Hypercapnia refers to an increase in the partial pressure of carbon dioxide (PCO2) in arterial blood, which is caused by hypoventilation or inadequate removal of CO2 from the lungs. A, B, and C all refer to respiratory or breathing-related terms, but only hypercapnia specifically describes an increase in arterial PCO2. Hypoglycemia refers to low blood sugar levels, which is unrelated to this question.
