drug computation.. help!

The order is digoxin 0.325 mg and the stock is 0.25 mg/tab.. how many tab/s to give?

A. 2 tabs

B. 3

C. 1.5

D. 3/4

Per answer key the answer is 3/4 but no explanation. I want to know how did it come up to that answer. Tnx

The order is dilantin 5 mg/kg in a 50 lbs patient to be divided in 3 equal doses. Stock is 125 mg/ml. Waht is the current amt to be administered?

A. 3 ml

B. 2

C. 4

D 2.0

The answer for #1 is 1.3, not 1.5. The ordered dose was 0.325 not 0.375. Also, you have to divide #2 by 3, because it is supposed to be split into 3 equal doses, so the answer is 0.3.

Correct and correct.

This was intentional on my part (uh yeah, right)... to demonstrate the value of showing all of one's work... which makes it very, very obvious where lie the mistakes.

Seriously, though... the single biggest problem people have in math is *not* showing all of their work... which leads to mistakes within the problem and which makes it difficult to figure out where one made an error...

and which eliminates your chance at partial credit :-)

In my case, I just over medicated both of my patients :-( because of not reading the problem carefully enough...

Another lesson: Always have somebody else check your work before you dose your patient... no matter how good you are at the calculations.

If you're certain you copied it correctly, then the only explanation is that you've got a crappy book full of typos.

For the first question, maybe option D is supposed to be 4/3 tabs instead of 3/4. 1.3 is approximately one and a third (=4/3).

For the second question, maybe option A is supposed to be 0.3 instead of 3?

Whoever wrote those questions, they really need a proof reader...

Maybe it's just a trick question and the answer is to question the orders. I mean come on who gives 1.3 tab of anything. And since no right answer to second question means you can't administer it so question the order ha ha. Am I thinking too much into it? Probably
