A nurse is reviewing the arterial blood gas values of a client who has chronic kidney disease. Which of the following sets of values should the nurse expect?

Choice A reason: This ABG profile suggests respiratory alkalosis with metabolic acidosis, which is not typical for chronic kidney disease. The elevated pH contradicts the expected acid-base disturbance. Choice B reason: This set of values indicates metabolic acidosis with partial respiratory compensation, which is common in chronic kidney disease due to the kidneys’ inability to excrete hydrogen ions and reabsorb bicarbonate effectively. Choice C reason: This profile reflects metabolic alkalosis with respiratory compensation, which is not characteristic of chronic kidney disease. CKD typically leads to acidosis, not alkalosis. Choice D reason: While the pH and bicarbonate are slightly low, the elevated PaCO₂ suggests respiratory acidosis rather than metabolic acidosis. This pattern is more consistent with pulmonary dysfunction than renal failure.
