A. Immediately after completion of the IV dose and 30 minutes before the next administration of the medication. B. One hour after completion of the IV dose and one hour before the next administration of the medication. C. Thirty minutes into the administration of the IV dose and 30 minutes before the next administration of the medication. D. Two hours after completion of the IV dose and two hours before the next administration of the medication.
