Solution

The correct answer is A. Hyperventilation increases blood pH by decreasing CO2 concentrations.

Here's the step-by-step explanation:

  1. Respiratory acidosis is a condition that occurs when the lungs can't remove enough of the carbon dioxide (CO2) produced by the body, leading to a decrease in blood pH (making the blood more acidic).

  2. Hyperventilation is a response to this condition. When a person hyperventilates, they breathe out more CO2 than usual.

  3. The decrease in CO2 concentration in the blood leads to a reaction that reduces the amount of hydrogen ions (which are responsible for acidity) in the blood.

  4. This results in an increase in blood pH, making the blood less acidic (or more alkaline).

So, hyperventilation is a compensatory mechanism that the body uses to correct the acid-base imbalance caused by respiratory acidosis.
