The healthcare provider prescribes amiodarone 0.5 mg/min intravenously (IV) for a client with a ventricular dysrhythmia. The IV bag contains amiodarone 360 mg in dextrose 5% in water (D5W) 200 mL. How many mL/hour should the nurse program the infusion pump?
(Enter numerical value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["17"]

To calculate the infusion rate, we need to use the formula:

Infusion rate (mL/h) = Dose (mg/min) x Volume (mL) / Concentration (mg)

Plugging in the given values, we get:

Infusion rate (mL/h) = 0.5 mg/min x 200 mL / 360 mg

Simplifying, we get:

Infusion rate (mL/h) = 100 mL / 360 min

Converting minutes to hours, we get:

Infusion rate (mL/h) = 100 mL / 6 h

Dividing both sides by 6, we get:

Infusion rate (mL/h) = 16.67 mL/h

Rounding to the nearest whole number, we get:

Infusion rate (mL/h) = 17 mL/h

Correct Answer is ["30"]

Explanation

To calculate the infusion rate, we need to use the formula:

Infusion rate (mL/h) = Dose (mg/min) x Volume (mL) / Concentration (mg)

Plugging in the given values, we get:

Infusion rate (mL/h) = 2 mg/min x 60 min / 4 mg/mL

Simplifying, we get:

Infusion rate (mL/h) = 30 mL/h

Correct Answer is ["6.88"]

Explanation

To calculate the volume of amrinone solution, we need to use the formula:

Volume (mL) = Dose (mg) x Dilution factor (mL/mg)

The dilution factor is the ratio of the volume of the vial to the amount of amrinone in the vial. In this case, it is 25 mL / 100 mg.

Plugging in the given values, we get:

Volume (mL) = 55 mg x 25 mL / 100 mg

Simplifying, we get:

Volume (mL) = 13.75 mL

To calculate the rate of administration, we need to divide the volume by the time. In this case, it is 2 minutes.

Plugging in the given values, we get:

Rate (mL/min) = 13.75 mL / 2 min

Simplifying, we get:

Rate (mL/min) = 6.875 mL/min

Rounding to the nearest hundredth, we get:

Rate (mL/min) = 6.88 mL/min
