Guest guest Posted August 6, 2003 Report Share Posted August 6, 2003 Hello everyone, I am brushing up on some math before classes begin next week. I have either become numb with anxiety or dumb with stupidity because today I am not getting it(ha). here goes: 1. How many milliequivalents of sodium are in 100 ml of saline? Molecular weight of sodium =23, chlorine =35. 2. You add 10 ml of 10% calcium gluconate to a 1 L bag of D5W. What is the concentration of calcium gluconate in the bag? 3. You reconstitute a vial of drug with 2.5 ml of saline. The vial contains 2,500,000 U of drug. what is the final concentration of drug in the vial? 4. An IV solution of heparin contains 10000 U in 500 ml and takes 2 hr to infuse. If the patient gets 1000 U of heparin per hour, what is the flow rate? 5. You add 10 ml of a 10% solution of calcium gluconate to a 500 ml IV bag. The flow rate is 30 gtt/min with an infusion set labeled 15gtt/ml. How much drug does the patient get per hour? 6. An adult dose of a drug is 1 g. What is the dose for a child weighing 50 lbs? 7. You have 10 ml of a 1% solution and need to dispense a 2 mg dose. how many doses are in the bottle? 8. You have a 5% solution of calcium gluconate, prices at $1 per 10 ml. There is a 200% markup on the product. Your order is for 1 g of calcium gluconate in a saline drip. What would the patient be charged for the drug? I do appreciate the help, as my brain is having difficulty computing... Thanks, Janet Quote Link to comment Share on other sites More sharing options...
