A normal total CO₂, increased pCO₂, and decreased pH is most correctly classified as:

Question

Quizplus · Accepted Answer

The decreased pH indicates some type of acidosis.The increased pCO₂ with normal total CO₂ suggests the presence of a normal bicarbonate level.With pCO₂ representing the respiratory component of the Henderson-Hasselbalch equation, the imbalance is respiratory acidosis.Since bicarbonate (the metabolic component) has not started to increase to regain the 20:1 ratio, the correct classification of the acid-base status is uncompensated respiratory acidosis.
