The healthcare provider prescribes heparin 1,400 units/hour intravenously (IV). The IV bag contains heparin 20,000 units in 250 mL dextrose 5% in water. How many mL/hour should the nurse program the infusion pump to deliver? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["17 mL\/hour"]
The correct answer is 17 mL/hour. To find the answer, we can use the following formula:
(mL/hour) = (units/hour) x (mL per unit)
Substituting the given values, we get:
(mL/hour) = (1,400) x (250 / 20,000)
Simplifying, we get:
(mL/hour) = (1,400) x (0.0125)
(mL/hour) = 17.5
(rounded mL/hour) = 17
Therefore, the nurse should program the infusion pump to deliver 17 mL/hour of heparin in dextrose 5% in water.

Correct Answer is ["1.5 mL"]
Explanation
The correct answer is 1.5 mL. To find the answer, we can use the following formula:
(mL to be administered) = (mg prescribed) / (mg per mL)
Substituting the given values, we get:
(mL to be administered) = (7.5) / (5)
Simplifying, we get:
(mL to be administered) = 1.5
Therefore, the nurse should administer 1.5 mL of metoclopramide from the prefilled syringe cartridge to the client.
Correct Answer is ["18 mL\/hour"]
Explanation
To find the answer, we can use the following steps:
- Convert the client's weight from pounds to kilograms by dividing by 2.2
- Calculate the dosage of dobutamine in mg/hour by multiplying the weight in kg by the rate in mcg/kg/min and by 60
- Divide the dosage of dobutamine in mg/hour by the concentration of dobutamine in the solution in mg/mL
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (165) / (2.2) = 75 kg
- (dose in mg/hour) = (2) x (75) x (60) = 9000 mcg/hour
- (dose in mg/hour) = (9000 x 10^-3) = 9 mg/hour
- (volume in mL/hour) = (9) / (50 / 1000) = 180 mL/hour
- (rounded volume in mL/hour) = 18 mL/hour
Therefore, the nurse should set the infusion pump to deliver 18 mL/hour of dobutamine hydrochloride in D5W.
