Name the imbalance using the following Arterial Blood Gas (ABG) values: pH 7.48, PaCO2 44, HCO3- 29

Choice A reason: Metabolic acidosis involves low pH (45 mm Hg) and low pH. Here, PaCO2 is 44 mm Hg (normal) and pH is 7.48 (alkalotic), with high HCO3-, pointing to a metabolic cause, not respiratory, making this choice incorrect for the ABG values. Choice D reason: Respiratory alkalosis involves low PaCO2 (<35 mm Hg) and high pH. With PaCO2 at 44 mm Hg (normal) and high HCO3- (29 mEq/L), the alkalosis is metabolic, not respiratory. This choice doesn’t match the ABG profile, making it incorrect.
