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.)

Answer and Explanation

The Correct Answer is ["20.7 mL\/hour"]

To find the answer, we can use the following steps:

- Calculate the dosage of dopamine in mcg/hour by multiplying the weight in kg by the rate in mcg/kg/min and by 60

- Calculate the concentration of dopamine in the solution by dividing the amount of dopamine in mg by the volume of solution in mL and multiplying by 1000

- Divide the dosage of dopamine by the concentration of dopamine in the solution to get the volume to be delivered in mL/hour

- Round the result to the nearest tenth

Using these steps, we get:

- (dosage of dopamine in mcg/hour) = (91) x (3) x (60) = 16,380 mcg/hour

- (concentration of dopamine in solution) = (400 / 250) x (1000) = 1600 mcg/mL

- (volume to be delivered in mL/hour) = (16,380) / (1600) = 10.2375 mL/hour

- (rounded volume to be delivered in mL/hour) = 10.2 mL/hour

Therefore, the nurse should program the infusion pump to deliver 10.2 mL/hour of dopamine in 5% dextrose injection to the patient.

Correct Answer is ["200 mL\/hour"]

Explanation

The correct answer is 200 mL/hour. To find the answer, we can use the following formula:

(mL/hour) = (mL/minute) x 60

Substituting the given values, we get:

(mL/hour) = (100 / 30) x 60

Simplifying, we get:

(mL/hour) = 3.333 x 60

(mL/hour) = 200

Therefore, the nurse should program the infusion pump to deliver 200 mL/hour of daptomycin in 0.9% Sodium Chloride.

Correct Answer is ["400 mL\/hour"]

Explanation

To find the answer, we can use the following formula:

(mL/hour) = (mL/minute) x 60

Substituting the given values, we get:

(mL/hour) = (1000 / 150) x 60

Simplifying, we get:

(mL/hour) = 6.667 x 60

(mL/hour) = 400

Therefore, the nurse should program the infusion pump to deliver 400 mL/hour of 0.9% Sodium chloride Injection, USP to the patient.
