If a patient is prescribed tablets gr 1/4 twice daily and the available tablets are gr 1, how many tablets would be given in a 7-day period?

To determine how many tablets are prescribed over a 7-day period, we first need to calculate the daily dose based on the prescription. The patient is prescribed gr 1/4 (which is one-quarter of a grain) twice daily. This means the total daily dosage is:

• Gr 1/4 dose in the morning
• Gr 1/4 dose in the evening

Thus, the total daily dosage is gr 1/4 + gr 1/4, which equals gr 1/2 (or half a grain) per day.

Next, we need to convert the total daily dosage into tablets. Since each available tablet is gr 1, the patient would need half a tablet for each dose. Therefore, the daily requirement in terms of tablets is:

• 1/2 tablet in the morning
• 1/2 tablet in the evening

This results in 1 tablet per day.

Now, to find out how many tablets the patient would take over a 7-day period, we simply multiply the daily dose (1 tablet) by the number of days (7):

1 tablet/day * 7 days = 7 tablets.

This makes the total number of tablets prescribed over a week 7 tablets.
