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 formulawhich converts an adult dose into a child’s dose using the child’s age. As in all literal equationsthis one has more than one variable, in fact it has three variables. They are:a = child’s age D = adult dosed = child’s dose The formula is d = I have been assigned to calculate a 4-year-old child’s dose of amoxicillin given that the adult dose is 500mg. d = The Cowling’s Rule formulad = I substituted500 for D and 4 for a. d = Following order of operations I added inside parentheses first. d = 2500/24Following order of operations the multiplication comes next. d = 104.166…. The division is the last step in solvingfor the child’s dose. The proper dose of amoxicillin for a 4-year-old child is 104mg. The next thing we are to do for this discussion is to determine a child’s age based upon the dose of
