A nurse is caring for a client who has chronic renal failure.
The client displays the following ABG results: pH 7.24, PaCO2 44 mm Hg, PaO2 84 mm Hg. HCO3 18 mEq/L, base excess -2, and O2 saturation 95%.
The nurse should conclude that the client has which of the following acid-base imbalances?
Respiratory acidosis.
Metabolic alkalosis.
Respiratory alkalosis.
Metabolic acidosis.
The Correct Answer is D
The client’s ABG results show a pH of 7.24, which is below the normal range of 7.35-7.45 and indicates acidosis.
The PaCO2 is within the normal range of 35-45 mm Hg, indicating that the acidosis is not caused by a respiratory issue.
The HCO3 level is 18 mEq/L, which is below the normal range of 22-28 mEq/L and indicates a primary metabolic cause for acidosis.
Respiratory acidosis is not indicated by the ABG results as the PaCO2 is within the normal range.
B) Metabolic alkalosis is not indicated by the ABG results as the pH and HCO3 levels are below their respective normal ranges.
C) Respiratory alkalosis is not indicated by the ABG results as the pH is below the normal range and the PaCO2 is within the normal range.
