If a doctor orders aspirin gr. x to be given, how many tablets should be administered?

• A. 2 tablets which are each gr. v
• B. 1 tablet which is gr. v
• C. 3 tablets which are each gr. v
• D. ½ tablet which is gr. v

Answer: (A)

To determine how many tablets should be administered, it’s essential to convert the units of measurement and understand the relation between grain and the dosage prescribed. In this context, the doctor has ordered aspirin in grains (gr.), specifically 10 grains (gr. x). The common form of aspirin available is often 5 grains per tablet (gr. v). To convert the total ordered dosage of 10 grains into the number of tablets needed, you can divide the ordered dose by the amount in each tablet. Since each tablet contains 5 grains (gr. v), you would calculate the following: 10 grains (ordered) divided by 5 grains (per tablet) equals 2 tablets. Thus, the correct approach is to recognize that to deliver a total of 10 grains of aspirin, you would need to administer 2 tablets, as each tablet provides 5 grains. This is why the first choice is correct.
