The correct answer is D. Combined respiratory and metabolic acidosis. (A) Compensated metabolic alkalosis would be reflected by the following: pH within normal limit (7.35-7.45), PCO2>; 45 mm Hg, HCO3>;26 mEq/L. (B) Respiratory acidosis would be reflected by thefollowing: pH < 7.35, PCO2 > 45 mm Hg, HCO3 within normal limits (22-26 mEq/L). (C)…

Question

A 52-year-old female client is admitted to the hospital in acute renal failure. She has been on hemodialysis for the past 2 years. Stat arterial blood gases are drawn on the client yielding the following results: pH 7.30, PCO2 51 mm Hg, HCO3, 18 mEq/L, PaO2, 84 mm Hg. The nurse would interpret these results as:

Options

ACompensated metabolic alkalosis
BRespiratory acidosis
CPartially compensated metabolic alkalosis
DCombined respiratory and metabolic acidosis

Explanation

(A) Compensated metabolic alkalosis would be reflected by the following: pH within normal limit (7.35-7.45), PCO2>; 45 mm Hg, HCO3>;26 mEq/L. (B) Respiratory acidosis would be reflected by thefollowing: pH < 7.35, PCO2 > 45 mm Hg, HCO3 within normal limits (22-26 mEq/L). (C) Partially compensated metabolic alkalosis would be reflected by the following: pH > 7.45, PCO2 > 45 mm Hg, HCO3 > 26 mEq/L. (D) Combined respiratory and metabolicacidosis would be reflected by the following: pH < 7.35, PCO2 > 45 mm Hg, HCO3 < 22 mEq/L.
