Hey guys I wanted some help with this question: The doctor prescribes 4 mg of I.M. morphine every 3 hours for your patient's pain. The drug is available in a prefilled syringe containing 10 mg of morphine/mL. How many milliliters of morphine should you waste?
I understand that you should give 0.4mL to the patient but how much do you waste? If anybody could help me understand this part of the question I would really appreciate it. Thanks guys
10 x 4
---- ---- = 10x =4= x=4/10 or .4ml Dose wanted Subtract dose wanted from original
1ml X. Quantity (1ml) 1ml minus .4=.6
.6 is wasted.
