I didn't have 3 for loading and 2 for initial dose. I over think things...before I had 1.5 tablets and 1 tablet thinking something completely different!
I am assuming that you did this one in your head, which is what I would have done. However, it is easy to get things mixed up when you don't write things out.
One of the things I do when I come up to a muti-part question is write out the infomation.
500 mg /tab
The first thing to notice is you have more then one unit and internally you should know that 1g = 1000 mg. You write this out or just keep it in mind, but at one point or another will need to do the conversion.
1g= 1000 mg or 1g= 2 tabs
Therefore 1g is 2 tabs and 1.5g is 3 tabs
For speed, durring the test write out the information and do the conversion inline
Step one writeout the info
step two convert g to mg
Step three, convert to tablets, when the answer is simply a 1:2 or 1:3 you may internalize the conversion to tabs and just write the answer.
In more complex problems where the tablets are someting odd like 175mg, you set up each part as its own problem as either DA or Ratio.
