3 Math for Allied Health (Math 117) Competency Review Part II DIRECTIONS: The Allied Health Competency Test will include a conversion chart and abbreviation list. You will be allowed to use a four function calculator available in the Assessment/Testing Center. To pass this test you will have to score at least 80%. To be assured of credit, please show work in detail. Be sure to use the correct unit with answers. 1. Change to decimals and arrange in order from smallest to largest: 0.08, 10 8, 0.8% 2. Order: 60 units U Insulin. (Assume 100 U in 1 ml) If a 1mL hypodermic syringe is used, how many ml should be administered?. How many ml will be given to a patient who has been prescribed 750 mg of DRUG from a vial labeled "1 g inject 2. ml of sterile water to yield 2.5 ml of DRUG. (Round to the nearest tenth of a ml.). A 220 lb patient is to receive all of a medicated IV fluid labeled 50 mg/500 cc. The doctor prescribes mcg/kg/min. Calculate the rate of flow using a microdropper administration set. (Round to the nearest whole drop.)

4 5. Drug Order: 6 1 grain phenobarbital. Medication on Hand: 1 grain per 1 tablet phenobarbital. How many tablets will you administer? 6. Order: 5% glucose 1000 ml to be administered IV over 8 hours via a 20 gtt/ml delivery system. After 2 hours 00 ml have been delivered. Calculate a new rate in order to finish on time. _ (Round to the nearest whole drop.) mg of Keflin is within 1000 ml of 5% glucose in water. If the IV is running at 0 gtt/min and the administration set is 15 gtt/ml, how long will it take the IV to run? (Round to the nearest whole minute.) b) If the IV is started at 10:15 A.M. on Dec. 17, when should it be completed? 8. A patient should receive 5 ml of DRUG per dose. If she has a 2 fluidounce bottle, how many doses will she have? _

5 9. How many grams of Dextrose does 500 ml of D10W contain? 10. A patient is to receive 2 tsp per dose four times a day. How many days will a 520 ml bottle last? 11. Order: 60 mg/m 2 Available: 8 mg/cc How many ml should be given a patient with a body surface of 1.2 m 2? 12. How many tablets should be ordered if the dose is 0.25 gram q6h for 5 days and the tablet strength is 0.5 g? 1a. A person has an IV medication order for 200 mg. It is to be diluted to 0 ml. Calculate the controller rate in ml/hr for this infusion if it is to be administered in 20 min. b. What will the rate be in gtt/min for the patient in part a) if a controller is not used and the set calibration is 60 gtt/ml?

6 1a. An IV of 0 ml of D5W containing 100 mcg of a medication is to be infused using a controller over a 25 min. period. The normal dosage of this drug is 5-7 mcg/kg/dose. The child weighs 15 kg. What is the normal dosge range for this child? _ b. If a 15 ml flush is used in part a), what rate in ml/hr will you set on the controller to deliver this medication is 25 min? (Assume that the 15 ml flush is part of the total volume for the IV.) 15. What heparin dosage in U/Hr. is being administered if 1 L of D5W containing 0,000 U is infusing at 60 ml/hr? b) What is the heparin dosage in U/min.? 16. Heparin has been ordered to infuse at the rate of 900 U/Hr. The solution has 0,000 U heparin in 1000 ml, and the set is calibrated at 15 gtt/ml. Calculate the flow rate in ml/hr. 17. A solution of 1 L D5W containing 20,000 U heparin is infusing at 28 gtt/min on a set calibrated at 15 gtt/ml. Calculate the number of ml/hr. (Round to the nearest whole ml.) b. the number of U/Hr.

7 18. The normal heparinizing range for adults is 20,000-0,000 Units/2 Hr. A patient is receiving 70mL/Hr of a solution of 18,000U heparin in 1L of D5W. The patient is receiving how many U/2Hrs.? Is this dosage within the average range? 19. Calculate the flow rate in ml/hr for a critical care drug that is to be delivered at 0.2 mg per min from a solution of 500 ml containing 100 mg. 20. The medication is to be infused at the rate of 1 mcg/kg/min. The patient weighs 9 kg. The strength of the solution is 0 mg in 500 ml. Calculate the flow rate in ml/hr. (Round to the nearest whole ml.) 21. A solution infusing has a concentration of 200 mg of DRUG in 50 ml. The pressure has regulated at a flow rate of 9 ml/hr. How many mcg is the patient now receiving per minute?
