Please help!! Need help with math problem

Published

I have a question that I need help with. The problem is this: The physician orders nitroglycerin tablets GRAIN sublingual every 5 minutes up to 3X a day for chest pain. The medication is supplied in 0.4-mg tablets. The patient took three tablets. How many Milligrams did she receive? The answer I got is 450 MG. Is this right?

I know we dont do others homework, but somethings could have been displayed better in which most people did. Thanks.

You cannot determine intent or tone from written messages on a message board. The intent could have been humor and you assumed condescension.

This is the type of problem that requires you to use your critical thinking skills. Why? Because there is a heck of a lot of extraneous distracting information in the stated problem. What is the pertinent information you need to do the math? Only 2 of those sentences are relevant.

And your answer of 450mg is way off. If a patient truly took that much nitro, she's probably on the floor with major hypotension.

Nah, Im thinking probably in the morgue already.

I guess I still have some optimism left. But yeah, celestial transfer.

I think that the OP is getting confused on converting the dose from apothecary to metric; grain 1/150 equals 0.4 mg.
