Problem
This patient is also low in calcium and requires an additional 40 mEq of calcium. Calcium is administered using a 20% CaCl2 solution. MW [CaCl2 monohydrate] = 129 g/mole (calcium MW = 40 g/mole) How many milliequivalents of Ca are there in 1 liter of a 20% CaCl2 solution? How many grams of calcium are present in a 100 ml of a 20% CaCl2 solution? What volume of 20% CaCl2 solution should be injected to add 40 mEq of Ca? Based upon the minimum value recommended for fluid intake, how much more fluid (in addition to the dextrose, saline and calcium) does this patient require?
