The primary healthcare provider (PHCP) prescribes dopamine at 2.5 mcg/kg/minute. The client weighs 198 lbs. The medication label reads dopamine 800 mg in 500 ml of dextrose 5% water (D5W). How many ml per hour will be administered to the client?

Answer :

Final answer:

To calculate the IV administration rate, convert the patient's weight to kilograms, calculate the prescribed medication rate in micrograms per minute, convert that to milligrams to match the medication label's units, and then use a proportional relationship to find the milliliters per hour rate. The result is approximately 8.44 mL/hour for the patient weighing 198 lbs, prescribed dopamine at 2.5 mcg/kg/minute with a medication concentration of 800 mg in 500 mL.

Explanation:

The student is asking how to calculate the intravenous drug administration rate in milliliters per hour for a medication prescription based on a patient's weight in pounds. To solve this, we first need to convert the patient's weight from pounds to kilograms. Since there are 2.2 pounds in a kilogram, we divide the patient's weight by 2.2. In this scenario, 198 lbs divided by 2.2 gives us approximately 90 kg.

Next, we calculate the total micrograms of dopamine that the patient should receive per minute, using the prescribed rate of 2.5 mcg/kg/minute. Multiplying 90 kg by 2.5 mcg/kg/minute yields 225 mcg/minute. Now, we need to determine how many milliliters of the dopamine solution this dosage corresponds to, given that the concentration of dopamine is 800 mg in 500 mL of solution.

To continue, we convert the dose to the same units as the concentration on the medication label, which is in milligrams. Since there are 1,000 micrograms in a milligram, 225 mcg is equivalent to 0.225 mg. The infusion needs to provide 0.225 mg of dopamine each minute to the patient.

We can then set up a proportional relationship since we know that 800 mg of dopamine is in 500 mL of solution:

800 mg of dopamine : 500 mL = 0.225 mg of dopamine : X mL

Solving for X, we find that X mL = (500 mL × 0.225 mg) / 800 mg, which simplifies to X mL = 0.140625 mL/minute. To find the administration rate per hour, we multiply by 60 minutes/hour, resulting in 8.4375 mL/hour. Therefore, the IV drip will administer approximately 8.44 mL of solution per hour.
