My friend got this on her pre-employment meds test, and it has both of us stumped. I even showed it to two people at work and we all came up with the same answer, which is not one of the choices listed.

A nitro drip at 24 mcg/min is ordered. The pharmacy sends a bottle of 250 ml D5W with 8 mg of nitro. The drip factor for the nitro tubing is 60 gtts/ml. What would be the flow rate for this IV?

A) 28 gtts/min
B) 36 gtts/min
C) 43 gtts/min
D) 47 gtts/min

We all came up with 45 gtts/min. What do you get?

[EricEnfermero]

Hmmm... I got the same.

I didn't try to figure it out, but since so many came up with the same answer, maybe it was a typo on the test.

[Jules A]

Are you sure this was the original problem? I'm also getting 45 which would have me furious if they didn't even offer the correct answer on the stinking test!

[lsyorke]

Yup, 45 works by my calculations!

[Altra]

45 here also ...

[TazziRN]

Thanks, guys! After I posted my doc came through here, and he's a whiz at calcs. He got the same answer. I'm going to tell my friend to write it in.

[GingerSue]

definitely tell them that the correct answer hasn't been included

I've experienced exam questions that just aren't right
(even in one I answered the wrong answer intentionally, and it marked it right) - my point here - the exam preparers make mistakes too - so tell them!

[morte]

yup, 45 here, too. betcha that 43 should have been a 45.....tell'em...

[morte]

on the other hand, how is the nitro supplied? having never worked critical care i dont know....is it already in solution, the amount of which would need to be added to the volume? if it comes 1 mg/ml....it would work out to 43 ggts/min......
