The Nurse Is Reviewing the ABG's (Arterial Blood Gas) Results

The nurse is reviewing the ABG's (Arterial Blood Gas) results of a patient who has been admitted for gastro intestinal (GI) bleeding and is now in Hypovolemic shock after severe vomiting and diarrhea for 3 days. The arterial blood gas results are pH 7.25, pCO2 39, pO2 77, HCO 316 and oxygen saturation 92%. What is the most probably cause of the arterial blood gas result?

A) Acute respiratory distress syndrome in response to shock.
B) The increased production of bicarbonate by the kidney as a compensatory response to shock.
C) Tachycardia as a compensatory mechanism in response to the Hypovolemic shock state.
D) The change from aerobic to anaerobic metabolism as a result of cell injury and damage.
