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.

Correct Answer is ["30"]
Explanation
The correct answer is 30 mL. To find the answer, we can use the following steps:
- Calculate the total daily dose of lamivudine in mg by multiplying the dose per administration by the number of administrations
- Divide the total daily dose of lamivudine in mg by the concentration of lamivudine in the oral solution in mg/mL
- Round the result to the nearest whole number
Using these steps, we get:
- (total daily dose in mg) = (150) x (2) = 300 mg
- (volume to be administered in mL) = (300) / (10) = 30 mL
- (rounded volume to be administered in mL) = 30 mL
Therefore, the Nurse should administer 30 mL of lamivudine oral solution in a 24 hour period.
Correct Answer is ["15"]
Explanation
To find the answer, we can use the following steps:
- Convert the child's weight from pounds to kilograms by dividing by 2.2
- Calculate the total daily dose of amoxicillin in mg by multiplying the weight in kg by the dosage in mg/kg/day
- Divide the total daily dose of amoxicillin in mg by the number of doses per day to get the dose per administration
- Divide the dose per administration in mg by the concentration of amoxicillin in mg/mL
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (66) / (2.2) = 30 kg
- (total daily dose in mg) = (80) x (30) = 2400 mg
- (dose per administration in mg) = (2400) / (2) = 1200 mg
- (volume per administration in mL) = (1200) / (400 / 5) = 15 mL
- (rounded volume per administration in mL) = 15 mL
Therefore, the nurse should administer 15 mL of amoxicillin oral suspension with each dose.
