Heparin 5,000 Units intravenous (IV) is prescribed as a loading dose, to be administered over 5 minutes for a client with thrombophlebitis. The vial is labeled, "10,000 units/mL." How many mL should the nurse administer?
(Enter numerical value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["0.5"]

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

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

Plugging in the given values, we get:

Volume (mL) = 5,000 units / 10,000 units/mL

Simplifying, we get:

Volume (mL) = 0.5 mL

Rounding to the nearest tenth, we get:

Volume (mL) = 0.5 mL

Correct Answer is ["1.3"]

Explanation

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 ["7200"]

Explanation

To calculate the amount of heparin received, we need to use the formula:

Amount (units) = Infusion rate (mL/h) x Time (h) x Concentration (units/mL)

First, we need to calculate the concentration of heparin in the solution by dividing the total units by the total volume. In this case, it is 20,000 units / 500 mL.

Plugging in the given values, we get:

Amount (units) = 15 mL/h x 12 h x 20,000 units / 500 mL

Simplifying, we get:

Amount (units) = 7,200 units
