Question

the md orders 125mg of a drug to be administered stat. available is 50 mg tablets of that drug.what should be administered

Answer 1

Answer:

2.5 tablets

Explanation:

First thing to do, in dealing with this type of questions, is to make sure that the prescribed dose and the dose of the drug in a single tablet are expressed in the same units. Since that is the case here (both doses are in milligrams), we can proceed.

So, one tablet has 50 mg of the drug and we need to administer 125 mg. That basically comes down to the equation:

50mg • x = 125 mg

where x is the number of tablets.

Now, we can find x:

x = 125 / 50

x = 2.5

So we need to administer 2.5 50 mg tablets in order for a patient to recieve 125 mg dose.
