<prompt> Increased anion gap acidosis is caused by all except:DiureticsUremiaKetoacidosisEthylene glycol  <response>: Ans: a Diuretics Ref: Harrison, 16th ed, p. 265,17th ed, p. 181Diuretics does not cause increased anion gap acidosisAnion gap - It represents the unmeasured anions in plasma. It helps to identify whether the acidosis is due to retention of H or another acid. The normal cations present in plasma are Na, K, Ca, Mg2The normal anions present in plasma are Cl-, HCO3-, albumin, phosphate, sulphate lactate, and other organic acids.The positive and negative charges are usually equal. But only Na, K, Cl- and HCO3 are easily measurable. So if we calculate the difference between the measured cations and anions, there will be a gap - the anion gap, which represents the unmeasured anions.Anion gap - Normal anion gap is 10-12 mmolLCauses of normal and high anion gap acidosis: refer above
