Calculating Dosage, Part 2
A) 10 mg tablets
1) 4 tablets (because 10 x 4 = 40 mg dose)
2) bid = 2 times per day
3) 3d = 3 days
4) 4 x 2 x 3 = 24 tablets
B) 250 mg tablets
C) 15 mg tablets
Calculating Dosage, Part 2: How many tablets of each dosage form are needed for a 40 mg dose taken bid for 3 days, using 10 mg tablets, 250 mg tablets, and 15 mg tablets?

To calculate the total number of tablets needed for sections B and C, let’s break it down step by step:
B) 250 mg tablets
– If the prescribed dose is 40 mg (as per A), you’d calculate the number of tablets needed as follows:
1) Determine how many 250 mg tablets are necessary to achieve a 40 mg dose:
[
text{Number of tablets} = frac{40 text{ mg}}{250 text{ mg/tablet}} = 0.16 text{ tablets}.
]
Since you can’t administer a fraction of a tablet, this dosage requires a different approach or may not be suitable with 250 mg tablets.
C) 15 mg tablets
– For 40 mg total dose:
1) Calculate how many 15 mg tablets are needed:
[
text{Number of tablets} = frac{40 text{ mg}}{15 text{ mg/tablet}} approx 2.67 text{ tablets}.
]
This means you would round up to 3 tablets because you cannot administer a fraction of a tablet in practice.
Summary:
– For 250 mg tablets, it’s impractical for a 40 mg dose.
– For 15 mg tablets, you would need 3 tablets to cover the 40 mg dose.
