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.)
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

Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mcg/min) x Volume (mL) / Concentration (mcg)
First, we need to calculate the concentration of nitroglycerin in the solution by dividing the total amount by the total volume. In this case, it is 100 mg / 250 mL.
Since 1 mg is equal to 1,000 mcg, we need to multiply the concentration by 1,000 to get the same units as the dose. In this case, it is 100,000 mcg / 250 mL.
Plugging in the given values, we get:
Infusion rate (mL/h) = 30 mcg/min x 250 mL / 100,000 mcg
Simplifying, we get:
Infusion rate (mL/h) = 0.075 mL/min
To convert minutes to hours, we need to multiply by 60. In this case, it is 0.075 mL/min x 60 min.
Simplifying, we get:
Infusion rate (mL/h) = 4.5 mL/h
Rounding to the nearest tenth, we get:
Infusion rate (mL/h) = 4.5 mL/h
Correct Answer is ["1"]
Explanation
To calculate the number of tablets, we need to use the formula:
Number of tablets = Dose (mcg) / Strength (mcg/tablet)
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, 154 pounds is equivalent to 69.916 kg.
Plugging in the given values, we get:
Number of tablets = 1.6 mcg/kg x 69.916 kg / 112 mcg
Simplifying, we get:
Number of tablets = 1
