Which of the Following is Characteristic of Acidosis

Question

Which of the following is characteristic of acidosis?
A) pH of 7.55
B) A decrease in the concentration of hydrogen ion in the blood
C) Urinary excretion of bicarbonate
D) pH less than 7.35

Accepted Answer

Acidosis is a state in which the pH of the blood is below the normal range of 7.35-7.45. Choice A is incorrect as a pH of 7.55 is more basic, not acidic. Choice B is incorrect as acidosis is characterized by an increase in the concentration of hydrogen ions in the blood. Choice C is incorrect as the urinary excretion of bicarbonate is a compensatory mechanism for alkalosis, not acidosis.
