Greetings fellow nurses in any field, I am trying to figure out drug conversions and need a site I can go to for reference..
Examples: convert 127 mcg = mg
65 mg - mcg
.238 mg = ? mcg
14 mg =?gm
7mg tablet=?mg/0.5 tablet
What is the correct way to convert these from one to the other please...andmake it wasy!!
As well I need to know the answer to this...and how to get the answer as well
Calculate the number of tablets or capsules administered for each dose over a 24 hour period
a/calcium carbonate 600 mg.p.o. t.i.d. The medication is available in 300 mg tablets.
b) Prednisone 40 mg po. u.i.d The medication is available in 5 mg tablets
Calculate the amount of liquid administered for each dose and for the 24 hour period
a) Docusate sodium syrup 200 mg.p.o. u.i.d. The medication is available in 4mg per mL
b) Gravol liquid 75 mg,p.o. q4h p.r.n. Gravol liquid is available in 15 mg per 5 mL
127 mcg = .127 mg
The way I do these calculations is if its asking u to go from small unit to big unit (mcg to mg) I divide and when going form big unit to small unit I multiply- So If u know that 1 milligram(mg) = 1000 micrograms(mcg) you divide 127/1000= .127
A) Calcium Carbonate 600mg p.o t.i.d. med available only in 300 mg tablets so we have a problem here! Here's the formula Ordered over on hand (600 is ordered, 300 is what u have on hand). Ordered
X Quantity = 600
X 1 =2
On hand 300
therefore you have to give the patient 2 tablets each 300 mg to make 1 dose!
Gravol liquid 75 mg /p.o /q 4 h /p.r.n available 15 mg per 5 ml
Here's that formuala again!
X quantity = 75
X 5 so 75/15= 5
On hand 15 then 5 X 5= 25( your answer)
So give 25 ml Gravol p.o/ q 4 h/ p.r.n
