If a patient is prescribed 150 mg of a medication and you have 75 mg tablets, how many tablets are needed?

To determine how many 75 mg tablets are needed to provide a total dose of 150 mg, you can use a simple calculation. You start by dividing the prescribed dose by the strength of the available tablet.

Here’s how the calculation works:

1. The total dose required is 150 mg.

2. Each tablet contains 75 mg.

3. To find out how many tablets are needed, you perform the following calculation:

[

\text{Number of tablets} = \frac{\text{Total dose required}}{\text{Dose per tablet}} = \frac{150 \text{ mg}}{75 \text{ mg/tablet}} = 2 \text{ tablets}

]

This calculation shows that you need 2 tablets of 75 mg each to reach the total of 150 mg prescribed. This is why the answer indicating 2 tablets is correct. It ensures that the patient receives the exact prescribed amount of medication.
