The nurse needs to administer 50 mg of ranitidine (Zantac) as an intermittent IV
infusion. The medication is diluted in 100 mL of 5% Dextrose solution. The nurse plans
to administer the infusion through an infusion pump over 15 minutes. The nurse should
set the pump to infuse how many mL per hour?

400
Rationale
Calculate as Volume/Time: 100 mL/15 minutes = 100 mL/.25 hour = 400
mL/hour Calculate as Ratio: Proportion:100 mL : .25 hr :: X mL : 1 hr100 =
.25X100/.25 = X = 400
A client with hypertension has a prescription for 8 mg of candesartan cilexetil PO
daily. The medication is available as a 16 mg tablet. How many tablets should the nurse
, administer?

8 mg: X tablets :: 16 mg: 1 tablet8 :: 16XX = 8/16 = 1/2 or 0.5 tablets
The nurse needs to administer a prescription of furosemide (Lasix) oral solution to a
child. The prescribed dose is 2 mg/kg. The child weighs 55 pounds. The medication is
available in a concentration of 10 mg/mL. How many mL should the nurse administer?

5
Rationale
First, calculate the weight in kg by dividing 55 by 2.2 (1 kg = 2.2 pounds) =
25 kg.Using ratio : proportion, calculate the correct dose in mg for the
child's weight in kg:25 kg : X mg :: 1 kg : 2 mg = 50 mg Now, use
Desired/Have X Volume:50 mg/10 mg X 1 mL = 5 mL
A client has a prescription for one liter of 0.9% Normal Saline solution to infuse over
twelve hours. The IV administration set delivers 15 drops/ml. The nurse should set the
drop rate at how many drops per minute?
