A nurse needs to infuse esmolol to a client weighing 65 kg. The dose on hand is 2,500 mg esmolol in 250 mL of fluid. The client requires a dose of 200 mcg/kg/min. Which rate should the nurse calculate to infuse this medication?
Round to the nearest whole number.
5 mL/hr
6 mL/hr
13 mL/hr
78 mL/hr
The Correct Answer is D
First, we need to calculate the total dose of esmolol required per minute: Total dose = Weight x Dose x 60 minutes
Total dose = 65 kg x 200 mcg/kg/min x 60 minutes Total dose = 780,000 mcg/min
Next, we need to convert the dose to milligrams (mg):
780,000 mcg/min = 780 mg/min
The concentration of the esmolol solution is 2,500 mg in 250 mL or 10 mg/mL. To deliver 780 mg/min at a concentration of 10 mg/mL, we need to infuse: Infusion rate = Total dose / Concentration
Infusion rate = 780 mg/min / 10 mg/mL Infusion rate = 78 mL/min
Rounding to the nearest whole number, the answer is D. 78 mL/hr.
Therefore, the nurse should calculate an infusion rate of 78 mL/hr to deliver the required dose of esmolol to the patient.

Correct Answer is C
Explanation
To calculate the total infusion time, we need to divide the total volume to be infused by the infusion rate:.
Total infusion time = Total volume to be infused / Infusion rate.
In this case, the total volume to be infused is 1000 mL, and the infusion rate is 250 mL/hr:.
Total infusion time = 1000 mL / 250 mL/hr. Total infusion time = 4 hours.
Therefore, the infusion will be completed 4 hours after it was started at 09:20, which would be at 13:20.
Correct Answer is C
Explanation
The correct answer is choice C, 3 tablets. To calculate the number of tablets, divide the ordered dose by the available dose:
75 mg ÷ 25 mg = 3
The nurse should administer 3 tablets of Coumadin 25 mg to the patient to give a total dose of 75 mg.
