Solumedrol 15mg IV is ordered. Solumedrol contains 40mg/ml. How lots mL wil be drawn into syringe?
Answer:
the calculation lookslike this:
40 mg/ml * X = 15 mg
of late solve for X
X = 15/40 = 0.375
so the answer is 0.375 ml
You seem to be struggling next to figuring out dosages.I guess you are making it much more complicated than it is. It's really just key fractions. You need 15 mg and one cc contains 40mg.so you want 15/40.reduce that to 3/8...and to be exact how much of a CC you need. If you needed 20 mg, you would involve 1/2 cc.
If you need 5 mg of a drug that have 10mg/ML (or cc) you need 5/10.shrink that to 1/2.so you need .5mL
Conversely if you entail 10mg of a drug that comes 5mg/cc...you need 10/5.which comes out to 2 cc.
Hope this help you!
