Question

a nurse is preparing to administer metformin 500 mg po twice a day to a patient. the amount available is metformin tablets 250 mg each. how many tablets should the nurse administer per dose? (round the answer to the nearest tenth/whole number. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Step1: Identify the required dose and available dose per tablet

The required dose per administration (per dose) is 500 mg, and each tablet contains 250 mg.

Step2: Calculate the number of tablets

To find the number of tablets, we divide the required dose by the dose per tablet. The formula is: Number of tablets = $\frac{\text{Required dose}}{\text{Dose per tablet}}$.
Substituting the values, we get Number of tablets = $\frac{500\space mg}{250\space mg/tablet}$.
Simplifying the fraction, $\frac{500}{250} = 2$.
