Seconal 35 mg is prescribed every 4 hours as needed for pain. The available concentration is 50 mg/mL. How many milliliters are required for a 35 mg dose?

Converting a prescribed milligram dose to the corresponding volume using the medication’s concentration is what this tests. With a concentration of 50 mg per 1 mL, the volume needed for a 35 mg dose is found by dividing the dose by the concentration: 35 mg ÷ 50 mg/mL = 0.7 mL. So, 0.7 mL of the solution supplies 35 mg because 0.7 mL × 50 mg/mL = 35 mg. In other terms, 0.5 mL would carry 25 mg, 0.35 mL would carry 17.5 mg, and 0.9 mL would carry 45 mg, so 0.7 mL is the correct amount for the required dose.
