Problem Set
Problem 8: Chronic compensation for diet rich in acid
Your patient presents with the following blood gases. When questioned about his diet, he admits to binging on citrus fruits in the past few weeks, and his favorite drinks are grapefruit and tomato juice.
| Patient's Value | Normal Value |
|
| pH | 7.32 | 7.35-7.45 |
| pCO2 | 25 mm Hg | 35-45 mm Hg |
| [HCO3-] | 15 mmol/liter | 24-28 mmol/liter |
What condition does this patient appear to have?
A. compensated respiratory acidosis B. compensated metabolic acidosis C. uncompensated respiratory acidosis D. uncompensated metabolic acidosis
