A physician ordered Regian (metoclopramide) 10 mg to be mixed with 50 mL of normal saline and infused over 15 minutes. A nurse must set the IV pump to deliver the medication per mL/hr as ordered.
At what rate should the solution be administered?

A.

100 mL/hr

B.

200 mL/hr

C.

50 mL/hr

D.

300 mL/hr

Answer and Explanation

The Correct Answer is B

To find the rate in mL/hr, you need to use the formula for infusion rate:


Infusion rate (mL/h) = (Total volume (mL) x Flow factor (gt/mL)) / Time (min) x 60 min/h


Since the total volume is 50 mL, the flow factor is 1 gt/mL, and the time is 15 minutes, plug in these values into the formula:


Infusion rate (mL/h) = (50 mL x 1 gt/mL) / 15 min x 60 min/h


Simplify and solve for the infusion rate:


Infusion rate (mL/h) = 200 mL/h


Therefore, the nurse should set the IV pump to deliver **200 mL/h** to infuse Regian 10 mg over 15 minutes.

Correct Answer is B

Explanation

To find the flow rate in mL/hr, you need to use the formula for infusion rate:


Infusion rate (mL/h) = Total volume (mL) / Time (h)


Since the total volume is 2.5 L and the time is 15 hours, plug in these values into the formula:


Infusion rate (mL/h) = 2.5 L / 15 h


However, before you can simplify and solve for the infusion rate, you need to convert the volume from liters to milliliters by multiplying by 1000:


Infusion rate (mL/h) = 2500 mL / 15 h

Simplify and solve for the infusion rate:


Infusion rate (mL/h) = 166.67 mL/h


Therefore, the flow rate for continuous infusion is **166.67 mL/h**.

Correct Answer is B

Explanation

Step 1 is Convert pounds to kilograms 110 lb ÷ 2.2 = 50 kg

Step 2 is Calculate dose in micrograms per minute 50 kg × 200 micrograms = 10,000 micrograms/min

Step 3 is Convert micrograms to milligrams 10,000 micrograms ÷ 1000 = 10 mg/min

Step 4 is Convert mg/min to mg/hr 10 mg × 60 = 600 mg/hr

Step 5 is Determine concentration of esmolol in mg/mL 2.5 grams × 1000 = 2500 mg 2500 mg ÷ 250 mL = 10 mg/mL

Step 6 is Calculate infusion rate in mL/hr 600 mg/hr ÷ 10 mg/mL = 60 mL/hr
