I am a New MISI Nurse but have been a nurse for many years. I work in a unit that sees so many GSW's and stab wounds that I can't see straight. Anyway, my problem is the constant factor. My new boss, who is great wants us to use the constant factor when figuring out mg to mcg, etc. I am having trouble figuring out this CF and the math that goes with it. My Clinical Team Leaders have been great but I don't always have the time to sit and figure these problems out. Any sites out there that I can visit that will help me with the constant factor? Any books? I have calculations on paper for most of the drugs but not all. Siam:banghead:
