Question

calcium carbonate 1000 mg daily is ordered in divided doses bid. 250 mg per tablet is available. how many tablets should you administer to the patient per dose? 2 3 4 5

Explanation:

Step1: Calculate daily dose per administration

Since it's divided bid (twice - daily), the daily dose of 1000 mg is divided into two equal doses. So, the dose per administration is $\frac{1000}{2}=500$ mg.

Step2: Calculate number of tablets per dose

Each tablet is 250 mg. Let the number of tablets be $n$. We use the formula $n=\frac{\text{Dose per administration}}{\text{Dose per tablet}}$. So, $n = \frac{500}{250}=2$.
