A nurse is preparing to administer acyclovir (zovirax) 5 mg/kg po every 8 hr to a client who weighs 75 lb. how many mg should the nurse adminster per dose?

The answer for this question is 170mg.

To calculate the drug doses first you need to change the patient weight into kilograms. If 75lb converted to kilograms it would be 34.0194kg. After that, you need to multiply 34kg with 5mg/kg so it would be 170mg.

But there is 200mg acyclovir tablet, not 170mg. In this case, you might need to make it into pulveres/powder.
