<prompt> A CLD patient was having pedal oedema and was prescribed thiazides. He complains of muscle cramps and excessive sleepiness. Work up shows the following repo. pH 7.55, pCO2 38 mmHg, Na 140, K 3.0mEq, Chloride 91mEq and HCO3 33. Comment on the diagnosis.Normal anion gap Metabolic alkalosisElevated anion gap metabolic alkalosisMetabolic alkalosis with compensated respiratory acidosisNormal anion gap metabolic alkalosis  <response>: CLD, pedal edema - GFR- RAAS stimulate Aldosterone Hypokalemic Metabolic alkalosis Here, AG Na - Cl- HCO3- 140 - 9133 16 The normal value for the AG repoed by clinical laboratories has declined with improved methodology for measuring plasma electrolytes, and ranges from 6 to 12 mmolL, with an average of 10 mmolL.
