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

Answer and Explanation

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

The Tylenol 3 medication contains codeine 30 mg and acetaminophen (APAP) 300 mg per tablet.

The physician has ordered Tylenol 3 30 mg every 4-6 hours as needed for pain. Therefore, the nurse should administer 1 tablet (containing 30 mg of codeine and 300 mg of APAP) every 4-6 hours as needed for pain..

It is important to note that the maximum daily dose of acetaminophen is 4,000 mg. Therefore, the nurse should monitor the total daily dose of acetaminophen the patient receives from all sources to ensure it does not exceed 4,000 mg.
