20 milligrams of the drug lincomycin is to be given for each kilogram of a person's weight the drug is be mixed with 250 cc of a normal saline solution, and the mixture is to be administered intravenously over a 1 hour period. weight 196 lb determine the dosage of the drug given
at what rate per minute should the 250 cc solution be adminstered

First you need to convert pounds to kilograms. 196 pounds is 88.904 kilograms. The directions tell you that 20 milligrams of the drug is to be administered for each kilogram of a person's weight.

You need to multiply 88.904 by 20. That should give you 1778.08 milligrams of lincomycin.

You would then mix 250 cc's of saline solution to the 1778.08 milligrams of lincomycin; but I think its just asking you how much lincomycin to administer.
