1.Given

Order :Cephalexin

Weight :100lbs (0.454*100=45.4kg)

Dose :10mg/kg

As it is given 1kg=10mg

Then 45.4kg=??mg

Cross multiply and divide

=45.4*10/1

=45.4*10

=454mg

Ans:The ordered dose is 454mg for the patient

2.Now from the above calculation the dose to be administered to the patient is 454mg (upon rounding off it is 450mg ) the conversion is made because the medication is available in capsule form

The size of the capsule to be selected is two 500mg capsule and one 250mg capsule. In a day three times it has to be administered do the actual size is 1362mg. In order to prevent overdose the lowest dose can be chosen for drug and patient safety .

The medication has to be administered once in every eight hours as it is TID (means thrice a day)
