Q1 QUESTION 1 OF 50
A nurse is initiating a dopamine infusion for a client experiencing cardiogenic shock. The client weighs 100 kg and is
prescribed dopamine at 3 mcg/kg/minute. The available solution is 400 mg of dopamine in 250 mL of D5W. What pump
settings are required to deliver the prescribed dose? (Select all that apply.)
A) Set the infusion rate to 11.3 mL/hr.
B) Calculate the total daily dose of dopamine.
C) Convert the client's weight to pounds for the calculation.
D) Ensure the concentration is expressed as mg/mL.
E) Program the pump for a rate of 18 mg/hr.
CORRECT ANSWER
A) Set the infusion rate to 11.3 mL/hr.
D) Ensure the concentration is expressed as mg/mL.
E) Program the pump for a rate of 18 mg/hr.

3 mL/hr) and verify the concentration (400 mg in 250 mL) to deliver the prescribed 18 mg/hr dose of dopamine. Calculating the daily
dose or converting weight to pounds are unnecessary steps for this calculation.
Q2 QUESTION 2 OF 50
A 72.4 kg client with severe hypertension is receiving a nitroprusside infusion. The prescribed rate is 75 mL/hour from a
solution of 50 mg of nitroprusside in 250 mL of D5W. Calculate the dosage in mcg/kg/minute the client is currently
receiving. (Enter numeric value only. Round to the nearest tenth.)
A) 3.1
B) 3.5
C) 2.8
D) 4.1
CORRECT ANSWER
B) 3.5
RATIONALE
5 mcg/kg/minute, calculated by determining the hourly milligram infusion rate, converting it to micrograms per minute, and then
dividing by the client's weight in kilograms. This calculation is essential for safe titration of potent vasoactive medications like
nitroprusside.
Q3 QUESTION 3 OF 50
The nurse is caring for a 70 kg adult client in the medical intensive care unit receiving a continuous infusion of dopamine.
The solution concentration is 800 mg in 500 mL of normal saline, and the current infusion rate is set at 5 mL/hr. Which of
the following calculations or actions is/are necessary to accurately assess the client's medication dosage? (Select all that
apply.)
A) Calculate the total hourly dose in milligrams.
B) Calculate the hourly dose in micrograms per kilogram.
C) Calculate the infusion rate in milliliters per minute.
D) Calculate the hourly dose in micrograms per kilogram per hour.
E) Convert the total volume of the infusate to milliliters.
F) Calculate the client's current infusion rate in milliliters per hour.
CORRECT ANSWER
A) Calculate the total hourly dose in milligrams.
B) Calculate the hourly dose in micrograms per kilogram.
Page 2
, RATIONALE
The nurse must first calculate the total milligrams per hour to determine the ordered dose before converting it to micrograms per
kilogram per minute, which is the standard unit for pediatric vasoactive drips and often used for clarity in adult critical care. Other
calculations are either unnecessary or already provided.
Q4 QUESTION 4 OF 50
A 68-year-old client with atrial fibrillation is prescribed amiodarone 1 gram to be added to 250 mL of 0.9% sodium chloride
for IV infusion. The programmed infusion pump is set to deliver the solution at 17 mL/hour. The prescriber wants to ensure
the client receives the medication at a rate equivalent to 1.1 mg per minute. To verify the current infusion rate in mg/minute,
what numeric value should the nurse calculate?
A) 1.0 mg/minute
B) 1.3 mg/minute
C) 1.1 mg/minute
D) 0.9 mg/minute
CORRECT ANSWER
C) 1.1 mg/minute
RATIONALE
The total amiodarone dose is 1000 mg in 250 mL, yielding a concentration of 4 mg/mL. An infusion rate of 17 mL/hour delivers 68
mg/hour (17 mL/hr * 4 mg/mL), which translates to 1.13 mg/minute (68 mg/hr / 60 min/hr), confirming the prescribed rate.
Q5 QUESTION 5 OF 50
The nurse is managing an infusion of esmolol (Brevibloc) for a 176-pound adult client in the telemetry unit. The current
infusion rate is 48 ml/hour, and the solution is concentrated at 10 mg/ml. The prescriber's order is for 100 mcg/kg/minute.
What is the current infusion rate in mcg/kg/minute? (Enter numeric value only.)
A) 100
B) 120
C) 80
D) 160
CORRECT ANSWER
A) 100
RATIONALE
2 lbs/kg), and the total mcg/minute delivered is 480,000 mcg (48 ml/hr * 10 mg/ml * 1000 mcg/mg). Dividing the total mcg/minute
by the client's weight in kg (480,000 mcg/min / 80 kg) yields 6,000 mcg/kg/minute, which is then divided by 60 minutes to arrive at
100 mcg/kg/minute.
