A provider prescribes 2 g of a medication to give to a client in eight divided doses over the next 24h.
How many mg should the nurse administer for each dose?
The Correct Answer is ["250"]
The correct answer is 250 mg.
Step 1: Convert grams to milligrams. 1 gram = 1000 milligrams. So, 2 grams = 2000 milligrams.
Step 2: Divide the total milligrams by the number of doses. 2000 mg / 8 doses = 250 mg per dose.
