will it take for the Glucerna to infuse? (Round to the nearest 10th decimal
and place only the numerical value in the space provided.)
1/7
,Infusion time:: 180 mL/35 mL per hour = 5.14 hours = 5.1 hours
3. 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
4. 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

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
