Dosage Calculation RN Fundamentals Assessment 3.0 Practice Test

To determine the correct number of tablets needed, it's essential to convert the prescribed dosage from milligrams to grams since the tablet strength is given in grams. The prescription states that the patient requires 750 mg of Gantrisin daily.

Since 1 gram (g) is equal to 1000 milligrams (mg), the conversion from milligrams to grams is:

750 mg = 750 mg ÷ 1000 = 0.75 g

Next, we need to find out how many tablets provide 0.75 g of the medication. Each tablet contains 0.5 g of Gantrisin. To find the number of tablets required to reach the prescribed dosage of 0.75 g, you can use the formula:

Number of tablets = Total dosage required (g) ÷ Dosage per tablet (g)

Substituting in the values:

Number of tablets = 0.75 g ÷ 0.5 g/tablet = 1.5 tablets

Since you cannot prescribe a half tablet in standard practice, it’s reasonable to round down to the nearest whole number for the purpose of medication administration if the practice allows. However, in this case, if the provider needs the total dosage accurately represented, administering
