AS A MATH PROBLEM:
The 12.1 mg amount is contained in a chewable tablet or in a 6-mL volume.\
a. For tablets
Rounding would give you tablets in a week,
and that is what a pharmacist would dispense for a week.
b. For liquid formulation:
Rounding would give you mL in a week.
A pharmacist would dispense 350mL if the prescription is for a week,
so that about 333mL could be taken out of the medicine bottle.
AS A REAL-LIFE QUESTION:
a. With 12.1 mg per tablets, 2 tablets would be 24.2mg,
which is close enough to 24 mg.
As a mother of a 100-pound child, you would be supposed to give
2 tablets every 6 hours, meaning times a day
That translates to
tablets per day, and
tablets per week.
The problem does not look that bad from the point of view of a mother.
A mother with a 4th-grade education should be competent enough to figure this out,
and would count to see if there are enough tablets in the medicine bottle for a 1 week vacation.
If mothers cannot do that, their schooling has failed them.
b. A measuring teaspoon has a volume of 5mL,
and the small measuring cups that come with many syrup medications have lines for 5mL, but not for 6mL.
However, a resourceful mother will figure out what to do.
A concentration of 12.1mg/6mL means
In 11mL you would have , and
in 12mg there would be ,
so a mother would give her 100-lb child 12 mL each time,
measured as accurately as she could manage.
That would mean
about each day, and
about each week.
