A client's arterial blood gas (ABG) results are pH 7.30, PaCO2 58 mmHg, HCO3 25 mEq/L, and PaO2 80 mmHg. What acid-base imbalance does the nurse interpret from these results?

The correct answer to the question "A client's arterial blood gas (ABG) results are pH 7.30, PaCO2 58 mmHg, HCO3 25 mEq/L, and PaO2 80 mmHg. What acid-base imbalance does the nurse interpret from these results?" is Option B: Respiratory acidosis, uncompensated.

The other options — A) Metabolic acidosis, C) Metabolic alkalosis, D) Respiratory alkalosis, partially compensated — are incorrect for this NCLEX-RN Exam Prep question. As explained above: The pH (7.30) is acidic. The PaCO2 (58 mmHg) is high, indicating a respiratory cause. The HCO3 (25 mEq/L) is within the normal range, meaning there is no renal compensation yet. Therefore, it is unco…
