Question

Order: Morphine sulfate 80 mg in 250 mL of IV fluid to infuse at

a rate of 20 mL/hr. Determine the dosage in mg/hr the client is
receiving. ONLY ENTER THE NUMERIC ANSWER.

Answer 1

To determine the dosage of morphine sulfate in mg/hr, calculate the amount of drug per mL (0.32 mg/mL) and then multiply it by the infusion rate (20 mL/hr), which results in a dosage of 6.4 mg/hr.

Step-by-step explanation:

To calculate the dosage of morphine sulfate in mg/hr that the client is receiving, you need to determine how much active drug is contained within the volume of fluid to infuse per hour.

First, you determine the concentration of the solution:

• 80 mg of morphine sulfate in 250 mL of IV fluid.

Then, calculate the amount of morphine sulfate per mL:

• 80 mg ÷ 250 mL = 0.32 mg/mL.

Finally, calculate the delivery rate in mg/hr:

• 0.32 mg/mL × 20 mL/hr = 6.4 mg/hr.

Therefore, the client is receiving 6.4 mg of morphine sulfate per hour.
