<prompt> How much Potassium is present in the Ringer Lactate solution1 mEqL4 mEqL2 mEqL6 mEqL  <response>: A litre provides 9 calories from lactate, sodium Na-130 mEq, potassium K-4 mEq, calcium Ca-3 mEq, chloride Cl--109 mEq and lactate - 28 mEq. The electrolyte content is isotonic 273 mOsmolliter, calc. in relation to the extracellular fluid approx. 280 mOsmolliter. The pH of the solution is 6.6 6.0 - 7. Ringers lactate solution RL, also known as sodium lactate solution and Hamanns solution, is a mixture of sodium chloride, sodium lactate, potassium chloride, and calcium chloride in water. It is used for replacing fluids and electrolytes in those who have low blood volume or low blood pressure Ref Davidson 23rd edition pg 368
