Hypocapnia will lead to which of the following conditions?
Hypoventilation due to acidosis
Hypoventilation due to alkalosis
Hyperventilation due to acidosis
Hyperventilation due to alkalosis
Hypocapnia does not affect ventilation rate.
The Correct Answer is D
A. Hypoventilation due to acidosis: Hypoventilation would increase CO₂, leading to respiratory acidosis, not hypocapnia.
B. Hypoventilation due to alkalosis: Hypocapnia is a result of hyperventilation, not hypoventilation.
C. Hyperventilation due to acidosis: Hyperventilation is a response to acidosis to blow off CO₂, but hypocapnia itself is a result of hyperventilation.
D. Hyperventilation due to alkalosis: Hypocapnia (low CO₂) leads to respiratory alkalosis. This occurs due to hyperventilation, which blows off too much CO₂.
E. Hypocapnia does not affect ventilation rate: CO₂ levels significantly influence ventilation via central chemoreceptors.

E. Digestive alkalosis: Not a recognized acid-base disturbance.
