A medication is ordered as 0.2 g. The available form is 100 mg tablets. How many tablets should be given?
A. 2.5 tablets
Calculation: Ordered Dose = 0.2 g Available Dose = 100 mg Convert Ordered Dose to mg Ordered Dose = 0.2 × 1000 = 200 mg Number of tablets = Ordered Dose / Available Dose = 200 / 100 = 2 tablets
B. 3 tablets
Calculation: Ordered Dose = 0.2 g Available Dose = 100 mg Convert Ordered Dose to mg Ordered Dose = 0.2 × 1000 = 200 mg Number of tablets = Ordered Dose / Available Dose = 200 / 100 = 2 tablets
C. 4 tablets

D. 2 tablets
Calculation: Ordered Dose = 0.2 g Available Dose = 100 mg Convert Ordered Dose to mg Ordered Dose = 0.2 × 1000 = 200 mg Number of tablets = Ordered Dose / Available Dose = 200 / 100 = 2 tablets
Full Explanation
Calculation:
Ordered Dose = 0.2 g
Available Dose = 100 mg
- Convert Ordered Dose to mg
Ordered Dose = 0.2 × 1000
= 200 mg
Number of tablets = Ordered Dose / Available Dose
= 200 / 100
