A client with deep vein thrombosis (DVT) is receiving a continuous intravenous (IV) infusion of heparin sodium 20,000 units in 5% dextrose injection, 500 mL. The infusion rate is 15 mL/hour. How many units of heparin should the client receive in 12 hours?
(Enter numerical value only.)
The Correct Answer is ["7200"]
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

Correct Answer is ["4.494"]
Explanation
To calculate the infusion rate, we need to use the same formula as in Text 1, but with a different volume of solution.
Plugging in the given values, we get:
Infusion rate (mL/h) = 2 mcg/min x 74.91 kg x 150 mL / 50,000 mcg
Simplifying, we get:
Infusion rate (mL/h) = 4.494 mL/h
Correct Answer is ["7672.32"]
Explanation
To calculate the amount of heparin, we need to use the formula:
Amount (units) = Dose (units/kg) x Weight (kg)
First, we need to convert the weight from pounds to kilograms by multiplying by 0.454. In this case, 211.2 pounds is equivalent to 95.904 kg.
Plugging inthe given values, we get:
Amount (units) = 80 units/kg x 95.904 kg
Simplifying, we get:
Amount (units) = 7,672.32 units
