Basic Drug Calculations: Problem 7
Ordered: D5W 50 ml with 20 mEq KCl to infuse at 8 mEq KCL/hr per IV pump. How many ml of solution will you administer per hour?
Ratio-proportion:

    20 mEq : 50 ml = 8 mEq : x
     20 x = 400
     x = 400/20 = 20 ml/hr

Fraction:

       20 mEq   =    8 mEq  
         50 ml                x  
         20 x = 400
         x = 400/20 = 20 ml/hr
