A nurse reviews the arterial blood gas (ABG) values of a client admitted with pneumonia: pH, 7.32; PaCO2, 48 mm Hg; PaO2, 70 mm Hg; and HCO3, 24 mEq/L. What do these values indicate?
Metabolic Acidosis
Respiratory Acidosis
Metabolic Alkalosis
Respiratory Alkalosis
The Correct Answer is B
A. Metabolic Acidosis
Metabolic acidosis is characterized by a low pH and low bicarbonate (HCO3) level. In this case, the pH is low (indicating acidosis), but the bicarbonate level is within the normal range, which is inconsistent with metabolic acidosis.
B. Respiratory Acidosis
This is correct. Respiratory acidosis is characterized by an elevated partial pressure of carbon dioxide (PaCO2), leading to a decrease in pH. The ABG values in this case indicate elevated PaCO2 and a low pH, consistent with respiratory acidosis.
C. Metabolic Alkalosis
Metabolic alkalosis is characterized by a high pH and high bicarbonate (HCO3) level. In this case, the pH is low (indicating acidosis), which is inconsistent with metabolic alkalosis.
D. Respiratory Alkalosis
Respiratory alkalosis is characterized by a low partial pressure of carbon dioxide (PaCO2) and a high pH. In this case, the PaCO2 is elevated, which is inconsistent with respiratory alkalosis.
