Week Two Discussion One Nicole Bartholomew MAT 221 November 25, 2017. For this discussion we are to use Cowling’s Rule to determine the child sized dose of a particular medicine. Cowling’s Rule is a formula which converts an adult dose into a child’s dose using the child’s age. The formula is d = D( a + 1) d = child’s dose, D = adult dose 24, a = child’s age 1 - I have been assigned to calculate a 8-year-old child’s dose of amoxicillin given that the adult dose is 1000mg. The Cowling’s Rule formula d = [D( a +1)] / (24) I substituted 1000 for D and 8 for a . d = [1000(8+1)] / (24) Following order of operations, I added inside parentheses first. d = [1000(9)] / (24) Following order of operations, the multiplication comes next. d = (9000) / (24) The division is the last step in solving for the child’s dose. d = 375 The proper dose of amoxicillin for a 8-year-old child is 375mg. 2 - The next thing we are to do for this discussion is to determine a child’s age based upon
