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"]
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.

Explanation
First, we need to find out how many mg of warfarin are in one vial. Since the vial is labeled 5 mg/single-use, we can assume that it contains 5 mg of warfarin.
Next, we need to find out how many mL of solution are in one vial. Since the instructions say to reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL, we can use the following formula:
Amount of solution= amount of water + amount of warfarin
Substituting the given values, we get:
Amount of solution = 2.7 + 5 =7.7 mL
Now, we need to find out how many mL of solution contain 2 mg of warfarin, which is the prescribed dose for the patient. We can use the following formula:
mL of solution = mg of warfarin/ concentration of warfarin
Substituting the given values, we get:
mL of solution = 2/2 = 1 mL
Therefore, the nurse should administer 1 mL of solution to the patient.
Correct Answer is ["21"]
Explanation
To find the answer, we can use the following formula:
(gtt/min) = (mL/hour) x (gtt/mL) / 60
Substituting the given values, we get:
(gtt/min) = (250 / 2) x (10) / 60
Simplifying, we get:
(gtt/min) = 125 x 10 / 60
(gtt/min) = 1250 / 60
(gtt/min) = 20.833
(rounded gtt/min) = 21
Therefore, the nurse should regulate the infusion at 21 gtt/min.
