55 year old male patient who is a know case of chronic kidney disease present to emergency with vomiting and Is diagnosed with uremic acidosis. His ABG analysis report is pH= 7.42 pCO2= 40 HCO3= 25 Na+= 140 mmol/L K+= 3 mmol/L Cl-= 95 mmol/L
High-Yield Explanation
PH is higher, but CO2 and HCO3 look normal. So look at Anion gap = 20 .
But difference in HCO3 = 0 so is a case of High Anion Gap metabolic acidosis + metabolic alkalosis.
