Question

3- A pharmacy intern had just finished mixing a morphine drip for a patient when he received word that the morphine drip was discontinued by the physician. the pharmacy intern had originally placed 5ml of morphine 20 mg/ml solution into 500 ml bag of dextrose. Rather than waste the solution , the intern decided to make the morphine drip into morphine PCA syringes, which contain 50ml of a 1 mg/ml morphine solution. Calculate how much 20 mg/ml of the morphine stock solution is needed to be added to the solution. Assume the volumes being added are negligible, meaning the final IV bag volume is 500 ml. round you answer to whole number.
