Answer 1

Given that a nurse is to administer ampicillin drug weighed 1,000 milligrams PO (given orally) per day and divided into four equal doses.

Amount of ampicillin drug present in each dose is equal to the total dosage of drug divided by the number of equal doses. This is calculated as follows:

Now, the capsules available contain 250 mg per capsule. Thus, the number of capsules which are needed to be administered per dose is calculated as follows:

Thus, the nurse should administer one capsule per dose.
