I've pretty much got the hang of doing all of the calculations with the exception of the ones like this mcg/kg/min Order: 3mcg/kg/min patient weighs 87.4 kg Supply: 50mg in 250mL I don't know if there are different ways of doing this, but I use the ratio and proportion method but, I can't get to that point (I've tried solving the problem and inserting it into this equation 50mg: 250mL :: "my super wrong answer"mg : xmL The answer never comes out right. For whatever reason, I'm having the most trouble with these. Help? Please? If someone could work it out all the way I would really appreciate it!
