Correct Answer is B
Explanation
To calculate the rate at which the nurse should infuse esmolol to the client, we need to determine the total amount of medication (in mg) required per minute and then convert it to mL/hr based on the concentration of the medication.
First, we need to calculate the total amount of esmolol required per minute:
Dose per minute = dose/kg/min x weight Dose per minute = 200 mcg/kg/min x 65 kg
To convert mcg to mg, divide by 1000:
Dose per minute = (200 mcg/kg/min x 65 kg) / 1000
Now, let's calculate the rate of infusion based on the concentration of the medication:
Rate of infusion (mL/hr) = (Dose per minute (mg/min) / Concentration (mg/mL)) x 60 min/hr
Given that the dose on hand is 2,500 mg esmolol in 250 mL of fluid:
Rate of infusion (mL/hr) = ((200 mcg/kg/min x 65 kg) / 1000 mg/mg) / (250 mL/2500 mg) x 60 min/hr
Simplifying the equation:
Rate of infusion (mL/hr) = (13 mg/min) / (1 mL/min) x 60 min/hr
Rate of infusion (mL/hr) = 13 mL/hr
Therefore, the rate at which the nurse should calculate to infuse esmolol is b. 13 mL/hr, rounded to the nearest whole number.
Correct Answer is C
Explanation
The patient is ordered 5 mg of IV Lopressor to be administered over 2 minutes. To calculate the rate of administration in mg/min, we can divide the dose in mg by the infusion time in minutes: 5 mg / 2 min = 2.5 mg/min.
A. 3.75 mg is incorrect because it is more than the calculated rate of administration.
B. 0.4 mg is incorrect because it is less than the calculated rate of administration.
C. 2.5 mg is the correct answer.
D. 5 mg is incorrect because it is double the calculated rate of administration.
