Based on your patient's ABG's what acid-base imbalance is present? pH 7.30 HCO3 23 PaCO2 49.

A. Respiratory alkalosis – Respiratory alkalosis is characterized by elevated pH (>7.45) and low PaCO₂ (7.45) and elevated HCO₃ (>28 mEq/L), which is not present here. D. Metabolic acidosis – Metabolic acidosis is indicated by low pH and low HCO₃ (<21 mEq/L), which is not the case in these ABG values.
