💊 NCLEX-RN Exam Prep

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?

A Metabolic acidosis
B Respiratory acidosis, uncompensated
C Metabolic alkalosis
D Respiratory alkalosis, partially compensated

✓ Correct Answer: Option B

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 uncompensated respiratory acidosis.
