WILL respond to PAIN
Term
Narcosis
Definition
Drug induced state of DEE SLEEP - Difficult to arouse patient

the state of general anesthesia that is sufficient for surgery to be performed
Term
How many mg/ml or g/dL are in a 5% solution
Definition
50mg/ml
Term

Definition
Kg * (mg/kg) = mg dose

mg dose/ [ ] of mg/ml = Volume dose
