If a patient is prescribed atenolol 100 mg and provided with 25 mg tablets, how many tablets should the nurse administer?

To determine the number of tablets to administer, divide the total prescribed dosage by the amount per tablet. The patient has been prescribed 100 mg of atenolol, and each tablet contains 25 mg.

When you take the prescribed dose of 100 mg and divide it by the dose per tablet, you get:

100 mg (prescribed) ÷ 25 mg (per tablet) = 4 tablets.

Thus, the nurse should administer a total of four tablets of 25 mg each to achieve the 100 mg dose that has been prescribed.
