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 ["1.2 mL"]
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 dose of enoxaparin in mg per administration by multiplying the weight in kg by the dosage in mg/kg
- Divide the dose in mg per administration by the concentration of enoxaparin in the prefilled syringe in mg/mL
- Multiply the volume in mL per administration by the number of administrations per day
- Round the result to the nearest tenth
Using these steps, we get:
- (weight in kg) = (132) / (2.2) = 60 kg
- (dose in mg per administration) = (1) x (60) = 60 mg
- (volume in mL per administration) = (60) / (60 / 0.6) = 0.6 mL
- (volume in mL per day) = (0.6) x (2) = 1.2 mL
- (rounded volume in mL per day) = 1.2 mL
Therefore, the nurse should administer 1.2 mL of enoxaparin per day.
Correct Answer is ["105"]
Explanation
To find the answer, we can use the following steps:
- Convert the infant's weight from grams to kilograms by dividing by 1000
- Multiply the weight in kilograms by the dosage in mg/kg/day
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (3,500) / (1000) = 3.5 kg
- (dose in mg/day) = (30) x (3.5) = 105 mg/day
- (rounded dose in mg/day) = 105 mg
Therefore, the nurse should administer 105 mg of ceftazidime daily to this infant.
