I have a problem similar to. I don't know how to tackle it. If anyone could help I would appreciate it. I'm sure if I saw how to work out the problem I'm sure to understand it. My teacher isn't the greatest at explaining things. Thank you. Your patient is to receive Gentamycin 150 mg IVPB q18h. You have to constitute the powdered form of the medication. The Gentamycin comes in a 260 mg multidose vial. The directions state that after reconstituting with 3.6 ml of sterile water there will be a volume of 4 ml in the vial. After reconstitution the medication must be mixed in 100 ml D5W and infused over 45 minutes. The drip factor of the IV is 20 gtt/ml. 1. After reconstitution, what is the strength of the gentamycin in the vial? 2. What volume of medication will you remove from the vial in order to administer the required dosage? & 3. What will the drip rate (gtt/min) be for the IVPB? PLEASE HELP!!!!
