Answer 1

Answer: First, let's find out how many times a 100-pound person would take the antihistamine in a week:

Every 6 hours * 24 hours/day = 4 times a day

4 times a day * 7 days/week = 28 times a week

Next, let's find the number of 13.2 mg chewable tablets taken in a week:

A typical dose of 19 mg * 28 doses/week = 532 mg

532 mg / 13.2 mg/tablet = 40 tablets

So, a 100-pound person would take 40 chewable tablets in a week following the prescribed dosage.

Now, let's find the amount of liquid antihistamine to be taken in a week:

A typical dose of 19 mg * 28 doses/week = 532 mg

532 mg / 13.2 mg/10 mL = 40.15 mL

So, a 100-pound person would take 40.15 mL of liquid antihistamine in a week following the prescribed dosage.
