Medication Calculation Practice Problems1. You have an order for Dobutamine to run at 5mcg/kg/min.The label on the syringe states:Patient Label on SyringeD10 in water injection 50 mlDobutamine injection 40 mg/ml 100 mgwt 3.54 kgfinal concentration = Dobutamine 2 mg/mlYour patient weighs 3.54 kg. What is the standard concentrationfor this patient’s weight?Using your Standard Concentration list, determine the standardconcentration. Does this match the concentration listed on thesyringe label?Now calculate how many ml will be delivered in an hour (the rate ofthe pump).Use this formula:ml/hr = (ordered dose) (kg) (time frame)standard concentration availableThe formula would be:ml/hr = (5 mcg/kg/min) (3.54) (60 min)2mg/mlNOTE: All units of measure must match. The unit of measurefor the ordered dose must match the unit of measure for standardconcentration.

For example, if the ordered dose is in mg, then the standardconcentration must be in mg, if mcg, then mcg, if units, units.The ordered dose time must match the time frame in the equation. Ifthe order is written in min, ex. 5 mcg/kg/min, then the time frame is60 minutes. If the order is written in hour, then the time frame is 1hour, ex. 5 units/kg/hr then the time frame is 1 hour.The formula written with matching units would be:ml/hr = (5 mcg/kg/min) (3.54) (60 min)2000mcg/mlNow solve for the answer.2. You have an order for Dobutamine to run at 10 mcg/kg/min. Yourpatient weighs 18 kg.What is the standard concentration for this patient’s weight?How fast will the pump run?

3. You have an order for Insulin to run at 0.08units/kg/hour. Yourpatient weighs 3.54 kg.What is the standard concentration for this patient’s weight?How fast will the pump run?4. You have an order for Heparin to run at 10 units/kg/hour. Yourpatient weighs 4.5 kg.How fast will the pump run?5. You have an order for Insulin gtt @ 0.01 units/kg/hr. Yourpatient weighs 22 kg.How fast will the pump run?6. You have an order for Epinephrine gtt @ 0.1 mcg/kg/min. Yourpatient weighs 12 kg.How fast will the pump run?7. You have an order for Dopamine gtt @ 15 mcg/kg/min. Yourpatient weighs 0.98 kg.How fast will the pump run?

11. A 22 month-old child weighing 10 kg is to receive penicillin-G300,000 units IM. The penicillin-G is available in 5,000,000units/vial and is to be reconstituted to a concentration of1,000,000 units/ml. How many milliliters should the childreceive?a. 0.03b. 0.3c. 3.012. A 5 year-old child who weighs 18 kg is to receive amoxicillin13.3 mg/kg po q 8h. The medication is available as a liquidcontaining 250 mg/5 mL. How many milliliters should the childreceive with each dose?a. 0.96b. 1.9c. 4.813. A 2 year-old child who has a body surface area (BSA) of 0.63m2 is to receive 1.5 mg/m2 of a drug. The drug is available in 1mg/ml vials. How many milliliters should the child receive?a. 0.68b. 0.95c. 1.914. A 4 month-old infant who weighs 7 kilograms has an order for 8mg of ranitidine po b.i.d..
