An order for gabapentin 900 mg is prescribed, and the available strength is 300 mg per capsule. How many capsules will the nurse administer?

To determine how many capsules of gabapentin are needed, first, divide the prescribed dose by the amount of drug contained in each capsule. In this case, the ordered dose is 900 mg and each capsule contains 300 mg.

When performing the calculation:

900 mg (prescribed dose) ÷ 300 mg (strength per capsule) = 3 capsules.

So, the nurse needs to administer a total of three capsules to meet the prescribed dose of 900 mg. This ensures that the patient receives the correct dosage for effective management of their condition. The calculation is straightforward and emphasizes the importance of accurate dosing in pharmacological therapies.
