Just went through and saw all the requests and I must say that you are AWESOME to help us all out! I start pharm 2 in august and did ok with dosage calc. but this looks a little hairy! Another tip my teacher taught us with dosage is the pig pharm which i thought was ingenious! There is a pig pharm that is located right down the middle of two counties. (you make up we used jefferson county and bullit county) all the ppl from jeff called the pharm the 1 gram pharm. But all the ppl from bullit called it the 1000 mg pharm. So on the 1 gram pharm there is 15 grain bins. And each grain bin feeds 60 mg piggies. 1g = 1000mg 1g = 15 gr 1gr = 60 mg also to calc up and down the metric: kg ............... kL ................... up lefting 3 spaces g ................ L .......................down right dirty 3 spaces mg .............. mL mcg make these with stair steps on the side so you can go up or down. so example i want to change 600 mg to grams. So I have to go up (mg is under g so its up LEFTING) so the decimal goes three spaces to the left. 600 mg = .6 g. EX: 0.6 L to mL.. L to mL is DOWN RIGHT DIRTY so.. 0.6 L = 600 mL. EX: 0.25 g to mg is down right dirty so.. 0.25 g = 250 mg found that i used these calcs alot and its a fun way to to remember them...Shout out to Ms. Obreezy!!
