Question: 1 / 400

How do you calculate the dosage in mg if you have a solution of 5 mg per ml and you need 10 ml?

20 mg

30 mg

40 mg

50 mg

To determine the total dosage in milligrams, you multiply the concentration of the solution by the volume you need to administer. In this case, the concentration is 5 mg per milliliter (ml) and the required volume is 10 ml.

The calculation is performed as follows:

1. Start with the concentration: 5 mg/ml.

2. Multiply that by the desired volume: 10 ml.

So, the calculation would be:

5 mg/ml × 10 ml = 50 mg.

Thus, the total dosage required is 50 mg, which corresponds with the answer selected. This method of calculation is essential in healthcare settings to ensure that patients receive the proper dosage of medication based on concentration and volume.
