Approach to Acid Base Disorders – 4

ABG:

• pH = 7.33
• pCO₂ = 30 mmHg
• HCO₃⁻ = 15 mEq/L
• BE = −10

Labs:

• Na⁺ = 117 mEq/L
• K⁺ = 3.9 mEq/L
• Cl⁻ = 92 mEq/L
• Albumin = 6 g/L
• Ca²⁺ = 3 mEq/L
• Phosphate = 0.6 mEq/L 

Based on the Stewart approach which of the following best describes the acid-base disorder

48-year-old man with type 1 diabetes was admitted with vomiting. The plasma sodium level was 132 mmol per litre, and the chloride level was 70 mmol per litre. Arterial blood gas values were as follows: pH, 7.432; PaCO2 , 36.5 mm Hg; HCO −, 24.3 mmol per litre; and SBE, -0.3 mmol per litre , lactate-20. Other plasma values included a glucose level of 448 mg per decilitre and an albumin level of 2.1 g per litre
