The healthcare provider prescribes filgrastim 5 mcg/kg subcutaneous (SubQ) for a client who weighs 176 pounds. The available vial is labeled, "Filgrastim 300 mcg/mL." Based on the client's weight, how many milliliters should the nurse administer?
(Enter numerical value only. If rounding is required, round to the nearest tenth.)
Answer and Explanation

The Correct Answer is ["1.3"]

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

Volume (mL) = Dose (mcg) / Concentration (mcg/mL)

First, we need to calculate the dose by multiplying the prescribed rate by the weight in kilograms. To convert the weight from pounds to kilograms, we multiply by 0.454. In this case, 176 pounds is equivalent to 79.904 kg.

Plugging in the given values, we get:

Volume (mL) = 5 mcg/kg x 79.904 kg / 300 mcg/mL

Simplifying, we get:

Volume (mL) = 1.331 mL

Rounding to the nearest tenth, we get:

Volume (mL) = 1.3 mL

Correct Answer is ["17"]

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) = 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 ["80"]

Explanation

First, we need to convert the patient’s weight from pounds to kilograms, since the dose is in mcg/kg/min. To do this, we use the metric equivalent that 1 kg = 2.2 lbs. So, we divide 132 by 2.2 and get 60 kg.

Next, we need to calculate the dose of dopamine in mcg/min for this patient. To do this, we multiply the ordered dose (2 mcg/kg/min) by the patient’s weight (60 kg). So, we get 2 x 60 = 120 mcg/min.

Then, we need to convert the dose of dopamine from mcg/min to mg/hour, since the IV bag contains dopamine in mg. To do this, we use the fact that 1 mg = 1000 mcg and 1 hour = 60 minutes. So, we divide 120 by 1000 and multiply by 60. So, we get 120 / 1000 x 60 = 7.2 mg/hour.

Finally, we need to calculate the infusion rate in mL/hour for this IV bag. To do this, we use the ratio of dopamine in mg to D5W in mL, which is 45 mg / 500 mL. So, we set up a proportion as follows:

45/500=7.2/x

To solve for x, we cross-multiply and get 45 x = 3600. Then, we divide both sides by 45 and get x = 80. So, the infusion rate is 80 mL/hour.

Therefore, the nurse should program the infusion pump to deliver 80 mL/hour. (If rounding is required, round to the nearest whole number.)
