If a patient needs 75 mg of a medication and has 150 mg tablets, how many tablets do they need to consume?

To determine how many tablets the patient needs to consume, start by understanding that each tablet contains 150 mg of the medication. The patient requires only 75 mg.

In this case, since one tablet (150 mg) exceeds the patient's requirement (75 mg), cutting one tablet in half would provide exactly the amount needed. Therefore, the patient only needs to take half of a tablet to achieve the prescribed dose of 75 mg. This means that taking one full tablet is unnecessary and results in an excess of the medication.

Thus, the answer indicates that only one tablet is involved, as it effectively communicates the need for half a tablet for the 75 mg dose, acknowledging that the patient cannot take a full tablet without exceeding the required amount.
