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. As in all literal equations this one has more than one variable, in fact it has three variables. They are : a = child’s age D = adult dose d = child’s dose The formula is d = I have been assigned to calculate a 9-year-old child’s dose of amoxicillin given that the adult dose is 500mg. d = The Cowling’s Rule formula d = I substituted 500 for D and 9 for a. d = Following order of operations I added inside parentheses first. d = 5000/24 Following order of operations the multiplication comes next. d = 208.333… The division is the last step in solving for the child’s dose. The proper dose of amoxicillin for a 9-year-old child is 208mg. The next thing we are to do for this discussion is to determine a child’s age based upon the
