Question

Order states: Tetracycline® 0.5 gm p.o. twice a day. Drug available is 250 mg per tablet. How many tablets would you give in 24 hours?

Answer 1

To find the number of tablets needed in 24 hours for a prescription of Tetracycline 0.5 gm p.o. twice a day, divide the total dosage by the dosage per tablet. In this case, 4 tablets are needed.

Step-by-step explanation:

To find how many tablets are needed per day, we need to determine the total dosage required and divide it by the dosage per tablet.

The prescription states to take Tetracycline 0.5 gm (500 mg) twice a day. Each tablet available contains 250 mg.

So, to find the number of tablets needed in 24 hours, we divide the total dosage by the dosage per tablet.

Total dosage per day = 0.5 gm x 2 = 1 gm = 1000 mg

Number of tablets needed in 24 hours = Total dosage per day / Dosage per tablet

= 1000 mg / 250 mg

= 4 tablets
