A nurse is caring for a client who has the following arterial blood gas results: HCO3-, 18 mEq, PaCO, 28 mm Hg and pH 7.30. The nurse recognizes the client is experiencing which of the following acid base imbalances?
Respiratory acidosis
Metabolic alkalosis
Respiratory alkalosis
Metabolic acidosis
The Correct Answer is D
A. Respiratory acidosis would typically involve an elevated PaCO2, which is not seen in this case.
B. Metabolic alkalosis is characterized by an elevated bicarbonate level, which is not present in this scenario.
C. Respiratory alkalosis would present with a low PaCO2 and an elevated pH, which is not the case here.
D. The low bicarbonate level (HCO3) 18mEq/L (normal range of 22-26 mEq/L), and low pH 7.30 (normal range of 7.35-7.45), indicate metabolic acidosis. suggesting acidemia. The PaCO2 is also low at 28 mm Hg, indicating a respiratory compensation for the metabolic acidosis.

Correct Answer is C
Explanation
A. Metabolic acidosis would involve a low pH and low bicarbonate level, which is not evident in the given arterial blood gas results.
B. The low pH (acidosis) and high PaCO2 (respiratory component) indicate respiratory acidosis. The increased HCO3 (normal range of 22-26 mEq/L), suggests a renal compensatory mechanism attempting to normalize the pH.
C. George Kent's arterial blood gas values indicate a lower pH and an elevated PaCO2, which are consistent with respiratory acidosis. The increased HCO3 ((normal range of 22-26 mEq/L), suggests a renal compensatory mechanism attempting to normalize the pH.
D. Metabolic alkalosis is not supported by the given arterial blood gas results.
Correct Answer is B
Explanation
A. Aluminum hydroxide can lead to increased serum magnesium levels, but this is not the reason for its preference in chronic kidney disease.
B. Aluminum hydroxide is preferred because it binds to dietary phosphate, reducing serum phosphorus levels in patients with chronic kidney disease who are prone to hyperphosphatemia.
C. Aluminum hydroxide does not significantly affect serum potassium levels.
D. Aluminum hydroxide can lead to decreased serum calcium levels due to binding, but this is not the primary reason for its preference in chronic kidney disease.
