Question

The physician has ordered 1.0 g of tetracycline to be given every six hours to a patient . If your stock on hand is 500 mg tablets how many will you need for one days treatment

Answer 1

Answer:

We will need 8 tablets for a one day treatment.

Explanation:

Mass of tetracycline ordered to be given = 1.0 g

Mass of tetracycline tablet = 500 mg = 0.5 g

Let the number of tablets be x

$x\times 0.5 g=1.0 g$

x = 2

1 day = 24 hours

2 tablets after every six hours

24 hours = 4 times in a day

Total tablets used in a day = 4 × 2 = 8 tablets

Answer 2

2 tablets every 6 hours. The patient will receive four doses of 2 tablets. The physician will need 8 tablets for one days treatment.
