The physician orders D5W 1000 mL to be administered over 4 hours. How much dextrose is in this order?
5g
25g
50g
75g
50g
Rationale: There is 50g of dextrose in this order. Use ratio and proportion to calculate. Therefore, 5% dextrose is 5g dextrose per 100 mL of solution. 5g / 100 mL = X grams / 1000 mL. 100X = 5000 . Therefore, X = 5000/100, or 50g.
