A client has the following arterial blood gas (ABG) results: pH 7.51, PaCO2 39 mm Hg, HCO3 32 mEq/L. How would the nurse interpret these results?
Normal values: pH: 7.35-7.45, PaCO2: 35-45 mm Hg, HCO3: 22-26 mEq/L
Uncompensated metabolic alkalosis
Uncompensated respiratory acidosis
Uncompensated metabolic acidosis
Uncompensated respiratory alkalosis
The Correct Answer is A
Choice A reason: The ABG results show an elevated pH and HCO3, which are indicative of metabolic alkalosis. The PaCO2 is within the normal range, suggesting that it is uncompensated.
Choice B reason: Respiratory acidosis would be indicated by an elevated PaCO2 and a decreased pH, which is not the case here.
Choice C reason: Metabolic acidosis would be indicated by a decreased pH and HCO3, which is not consistent with the given results.
Choice D reason: Respiratory alkalosis would be indicated by a decreased PaCO2 and an increased pH, which is not consistent with the given results.

Correct Answer is B
Explanation
Choice A reason: Impaired elimination may be a concern with pancreatitis due to potential complications affecting the gastrointestinal tract, but it is not the immediate priority.
Choice B reason: Fluid imbalance is the most critical issue in acute pancreatitis, as evidenced by inelastic skin turgor and concentrated urine, indicating dehydration, which can exacerbate the condition and lead to hypovolemic shock.
Choice C reason: Fever may be present due to inflammation or infection, but the temperature provided is not indicative of a significant fever and is not the priority over fluid imbalance.
Choice D reason: Nausea is a symptom of acute pancreatitis and while it needs to be managed, it is not the priority over fluid imbalance.
