Dosage Calculations Test 1 KEY Mandatory Questions and CORRECT Answers

You are preparing to infuse Ensure 1/2 strength at 60 mL/hour. The Ensure is available in 240 mL cans. You mix one can of ensure with 240 mL of water to obtain the 1/2 strength. How many hours will it take for the feeding to infuse? (Place only the numerical value in the space provided.) - 240 Ensure + 240 water = 480 total volume. 480/60 mL/hr = 8 hours. A client is receiving Glucerna 180 mL at 35 mL/hour. How many hours will it take for the Glucerna to infuse? (Round to the nearest 10th decimal and place only the numerical value in the space provided.) Infusion time: - 180 mL/35 mL per hour = 5.14 hours = 5.1 hours A client is receiving Osmolyte 240 mL at 40 mL per hour via an enteral tube. How many hours will it take the Osmolyte to infuse? (Place only the numerical value in the space provided.) - 240 mL/40 mL/hr = 6 hours The provider prescribes aminophylline 15 mcg/kg/min for a child with status asthmaticus. The child weighs 44 pounds. The aminophylline bag is labeled 500 mg/500 mL of NS. What rate will you program the infusion pump to deliver? (Place only the numerical value in the space provided.) - 44/2.2 = 20 kg; 15/1000 = 0.015 X 20 = 0.3 X 60 = 18 mg/hr; 18 mg/500 mg X 500 mL = 18 mL/hr The provider prescribes aminophylline 15 mcg/kg/min for a child with status asthmaticus. The child weighs 44 pounds. The aminophylline bag is labeled 500 mg/500 mL of NS. What volume will you set the infusion pump to infuse? (Place only the numerical value in the space provided.) - You infuse the total volume of the bag which is 500 mL. A client is prescribed dopamine 8 mcg/kg/min. The client weighs 198 pounds. The dopamine available is 800 mg in 500 mL of D5W. What rate will you infuse this medication using an IV pump? (Place only the numerical value in the space provided.) - 198/2.2 = 90 kg; 8/1000 = 0.008 X 90 = 0.72 X 60 = 43.2 mg/hr; 43.2/800 X 500 = 27 mL/hr You enter a client's room and the pump reads 45 mL/hour with a volume to be infused of 500 mL. The label on the bag reads lidocaine 2 g in 500 mL of D5W. What dose in mg/min of the lidocaine is this client receiving? (Place only the numerical value in the space provided.) - X g/2 g X 500 mL = 45 mL/hr; Multiple each side of the equation by 2. 500X = 90. X=90/500 = 0.18 g/hr; 0.18 X 1000 = 180 mg/hr. 180/60 = 3 mg/min A client had 1 glass of apple juice, 1 bowl of oatmeal, 1/2 cup coffee, 1 carton of milk, and 1 slice of toast for breakfast. A juice glass is 3 ounces, a coffee cup is 6 ounces and a carton of milk is 8 ounces. How many mL of fluid did the client drink this meal? (Place only the numerical value in the space provided.) - 1 glass of juice is 3 oz, 1/2 cup of coffee is 3 oz, and 1 carton of milk is 8 oz. 3+3+8 =14 oz; 14 X 30 = 420 mL A client is receiving 1000 mL of 0.9% sodium chloride at 100 mL per hour. The infusion began at 0800. How many mL of fluid will be remaining at 1330? (Place only the numerical value in the space provided.) - 0800 to 1330 is 5.5 hours; 100 mL/hr X 5.5 hrs = 550 mL infused; 1000 mL-550 mL = 450 mL remaining A client is to receive 500 mL of D5 1/2 NS with 30 mEq KCL over four hours. How many mL/hr will you set the IV pump? (Place only the numerical value in the space provided.) - 500 mL/4 hours = 125 mL/hr
