Final answer:
Based on the ABG results provided, the client has metabolic acidosis. The blood pH is below the normal range, indicating acidosis, and the HCO3 value is lower than normal, indicating a deficiency of bicarbonate.
Step-by-step explanation:
Based on the ABG results provided, the nurse should identify that the client has metabolic acidosis. In metabolic acidosis, the blood pH is below the normal range of 7.35-7.45, indicating acidosis. The pH value of 7.28 shows that the blood is more acidic than normal. The HCO3 value of 14 mEq/L is lower than the normal range of 22-28 mEq/L, indicating a deficiency of bicarbonate.
