"Metabolic acidosis" is an incorrect answer because the pH is low and the HCO3 is within normal range.
This ABG result indicates that the client has an excess of carbon dioxide (CO2) due to hypoventilation.
"Respiratory alkalosis" is an incorrect answer because the pH is low and the PaCO2 is elevated.
"Metabolic alkalosis" is an incorrect answer because the HCO3 is within normal range, and the pH is low.
This ABG result indicates that the client has an excess of carbon dioxide (CO2) due to hypoventilation.
A. "Metabolic acidosis" is an incorrect answer because the pH is low and the HCO3 is within normal range.
C. "Respiratory alkalosis" is an incorrect answer because the pH is low and the PaCO2 is elevated.
D. "Metabolic alkalosis" is an incorrect answer because the HCO3 is within normal range, and the pH is low.
Explanation: The ABG result shows a low pH, elevated PaCO2, and normal HCO3, indicating respiratory acidosis. This condition can be caused by conditions that affect breathing, such as pneumonia, asthma, or chronic obstructive pulmonary disease (COPD).
