A prescription for azithromycin requires 500 mg for 3 days. If available as 250 mg scored tablets, how many tablets per dose should be given?

To determine the number of tablets to be administered per dose, we first need to analyze the amount of medication required and the dosage form available.

The prescription calls for a total of 500 mg of azithromycin per dose. The tablets available are scored and contain 250 mg each.

To find out how many tablets are needed to achieve the required dosage of 500 mg, we can perform a simple calculation:

1. Start with the required dose (500 mg).

2. Divide this by the strength of each tablet (250 mg per tablet):

[

\text{Number of tablets} = \frac{500 , \text{mg}}{250 , \text{mg/tablet}} = 2 , \text{tablets}

]

Thus, each dose requires 2 tablets of 250 mg to reach the required 500 mg. Therefore, the correct answer is that 2 tablets should be given per dose.

This method illustrates the importance of understanding how to manipulate dosage strengths and ensures accurate administration of medications based on prescription orders.
