Question

When a client has an arterial blood PH of 7.48, which buffer action will bring the pH back to normal?

a) Carbonic acid dissociation.
b) Bicarbonate ion secretion.
c) Hydrogen ion retention.
d) Oxygen dissociation.

Answer 1

The carbonic acid dissociation buffer action will bring the arterial blood pH back to normal when it is 7.48.

Step-by-step explanation:

The buffer system that would bring the arterial blood pH back to normal when it is 7.48 is the carbonic acid dissociation buffer action. Carbonic acid and bicarbonate ions are present in the blood in a 20:1 ratio, and this capture system is most efficient at buffering changes that would make the blood more acidic. The level of bicarbonate in the blood is controlled through the renal system, where bicarbonate ions are conserved and passed back into the blood.
