1. A young woman is found comatose, having taken an unknown number of sleeping pills an unknown time before. An arterial blood sample yields the following values: pH=6.90, HCO3=13 meq/liter, paCO2=68 mmHg. This patient's acid-base status is most accurately described as: a. uncompensated metabolic acidosis. b. Uncompensated respiratory alkalosis. c. Mixed metabolic and respiratory acidosis. d. Respiratory acidosis with partial renal compensation.

Step 1
The patient's arterial blood sample shows a pH of 6.90, which is below the normal range (7.35-7.45), indicating acidemia. The bicarbonate (HCO3-) level is 13 meq/liter, which is below the normal range of 22-26 meq/liter, indicating a loss of bicarbonate or an Show more…

A 24-year-old female reported to the emergency with difficulty in breathing. History revealed that she had ingested some unknown drug. The blood chemistry revealed the following: pH 7.1; pCO2: 55 mm Hg (above normal level); and HCO3-: 17 meq/L (below normal level). Which of the following is the most appropriate acid-base imbalance in the above said condition?
