The doctor orders Pepcid 10 mg by mouth three times a day. Instructions on the container say to reconstitute with water to make a concentration of 0.5 g/3 mL. How many ml/dose would you administer?

The concentration provided is 0.5 g/3 mL. Convert grams to milligrams: 0.5 g=500 mg Now, the concentration is 500 mg/3 mL. Find the concentration in mg/mL: Concentration=(500 mg/3 mL)≈166.67 mg/mL Next, to find the volume needed for a 10 mg dose, use the formula: Volume=(Desired dose (mg)/Concentration (mg/mL) 10 mg/166.67 mg/mL≈0.06 mL/dose
