If Metronidazole 0.75 g is ordered daily and the patient has 14 tablets of 375 mg each, how many days will this supply last?

To determine how many days the supply of Metronidazole tablets will last, first, we need to understand the total amount of medication available and the daily dosage required.

The order specifies a daily dose of Metronidazole at 0.75 grams. This needs to be converted into milligrams for easier comparison since the tablets are measured in milligrams.

0.75 grams is equal to 750 milligrams (since 1 gram = 1000 milligrams).

Now, the patient has 14 tablets, each containing 375 milligrams. To calculate the total amount of Metronidazole available, multiply the number of tablets by the amount in each tablet:

14 tablets × 375 mg/tablet = 5250 mg total.

Next, to find out how many days this supply will last, divide the total amount available by the daily dose:

5250 mg ÷ 750 mg/day = 7 days.

This calculation shows that the supply of Metronidazole will last for 7 days, confirming that this is the correct answer.
