<prompt> Which of the following condition is associated with normal anion gap acidosis ?Lactic acidosisKeto acidosisMethanol PoisoningHyperchloremic acidosis  <response>: All evaluations of acid-base disorders should include a simple calculation of the AG; it represents those unmeasured anions in plasma normally 10 to 12 mmolL and is calculated as follows: AG Na - CI- HCOs . When acid anions such as acetoacetate and lactate accumulate in extracellular fluid, the AG increases causing a high AG acidosis. An increase in the AG is most often due to an increase in unmeasured anions and less commonly is due to a decrease in unmeasured cations calcium, magnesium, potassium.
