A patient who weighs 91 kg receives a prescription for a continuous infusion of dopamine at 3 mcg/kg/min. The solution is labeled, “Dopamine 400 mg in 5% Dextrose injection 250 mL.” 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 tenth.)
The Correct Answer is ["10.2"]
To determine the infusion rate in mL/hour for the dopamine solution:
-
Calculate the total dose per minute:
3 mcg/kg/min×91 kg=273 mcg/min3mcg/kg/min×91kg=273mcg/min. -
Convert mcg/min to mcg/hour:
273 mcg/min×60 min/hour=16,380 mcg/hour273mcg/min×60min/hour=16,380mcg/hour. -
Convert mcg to mg:
16,380 mcg÷1,000=16.38 mg/hour16,380mcg÷1,000=16.38mg/hour. -
Determine the concentration of the solution:
400 mg÷250 mL=1.6 mg/mL400mg÷250mL=1.6mg/mL. -
Calculate the mL/hour required:
16.38 mg/hour÷1.6 mg/mL=10.2375 mL/hour16.38mg/hour÷1.6mg/mL=10.2375mL/hour.
Rounded to the nearest tenth:
10.2 mL/hour.

Correct Answer is ["15"]
Explanation
To find the answer, we can use the following formula:
(number of doses) = (amount of liraglutide in Pen) / (dose of liraglutide prescribed)
Substituting the given values, we get:
(number of doses) = (18) / (1.2)
Simplifying, we get:
(number of doses) = 15
Therefore, the nurse should tell the client that each liraglutide Pen contains 15 doses of liraglutide.
Correct Answer is ["168"]
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 mg/kg
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (185) / (2.2) = 84.091 kg
- (dose in mg) = (2) x (84.091) = 168.182 mg
- (rounded dose in mg) = 168 mg
Therefore, the nurse should prepare to administer 168 mg of zidovudine IV to the client.
