Quizplus · Accepted Answer

An ABG provides information on the levels of carbon dioxide and oxygen, as well as the pH, bicarbonate, and partial pressure of oxygen in the arterial blood. Bicarbonate (HCO3-) is one of the most important indicators of an acid-base imbalance, as it reflects the metabolic component of the acid-base balance. Changes in the levels of bicarbonate can indicate metabolic acidosis or alkalosis. Therefore, the answer is D- Bicarbonate.
