If a tablet contains 250 mg and the patient needs 1000 mg, how many tablets should be given?

To determine how many tablets a patient should receive, you start by looking at the information provided: each tablet contains 250 mg of the medication. The patient's required dosage is 1000 mg.

You can calculate the number of tablets needed by dividing the total required dosage by the amount of medication in one tablet. In this case, you take 1000 mg (the total dosage needed) and divide it by 250 mg (the amount in each tablet):

1000 mg ÷ 250 mg/tablet = 4 tablets.

This calculation shows that the patient needs four tablets to meet the required dosage of 1000 mg, making this the correct answer. Understanding this calculation method is crucial for ensuring that patients receive the correct dosage of their medications based on the strength of the individual tablets.
