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 ["4.5"]
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 ["30"]
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) = 2 mg/min x 60 min / 4 mg/mL
Simplifying, we get:
Infusion rate (mL/h) = 30 mL/h
