Dobutamine hydrochloride 2 mcg/kg/min is prescribed for a client weighing 165 pounds. The solution is mixed with 50 mg of dobutamine in 1,000 mL of D5W. The nurse should set the infusion pump to deliver how many mL/hour? (Enter numeric value only.)
The Correct Answer is ["180"]
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
Therefore, the nurse should set the infusion pump to deliver 180 mL/hour of dobutamine hydrochloride in D5W.

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.
Correct Answer is ["9000"]
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
- Multiply the weight in kilograms by the dosage in units/kg
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (198) / (2.2) = 90 kg
- (dose in units) = (100) x (90) = 9000 units
- (rounded dose in units) = 9000 units
Therefore, the nurse should administer 9000 units of IV Heparin to the client.
