The doctor orders 1 gram of an oral antibiotic to be given prior to a procedure. the office carries 250mg tablets. how many would you administer?

We know that 1g=1000 mg thus

250 g=250/1000=1/4 g

hence the number of drugs to administer given that the doctor instructed for 1 g antibiotics will be:

(amount ordered) / (the amount in 1 tablet)

1 / (1/4)

=4 tablets

Since the doctor requires 1 gram of the oral antibiotic and the tablets are 250mg each, we would need to administer 1 gram = 1000 mg / 250 mg/tablet = 4 total tablets. This would provide the necessary dose of the medication to the patient which is needed in order to start the procedure.
