A patient with deep vein thrombosis (DVT) is receiving a continuous infusion of Heparin Sodium 20,000 Units in 5% Dextrose Injection 500 mL at the rate of 25 mL/hour. How many units of heparin should the client receive in 12 hours? (Enter numeric value only.)
The Correct Answer is ["1200"]
To find the answer, we can use the following formula:
(units of heparin) = (mL/hour) x (hours) x (units per mL)
Substituting the given values, we get:
(units of heparin) = (25) x (12) x (20,000 / 500)
Simplifying, we get:
(units of heparin) = (25) x (12) x (40)
(units of heparin) = 1200
Therefore, the client should receive 1200 units of heparin in 12 hours.

Correct Answer is ["1.2 mL"]
Explanation
To find the answer, we can use the following steps:
- Convert the client's weight from pounds to kilograms by dividing by 2.2
- Calculate the dose of enoxaparin in mg per administration by multiplying the weight in kg by the dosage in mg/kg
- Divide the dose in mg per administration by the concentration of enoxaparin in the prefilled syringe in mg/mL
- Multiply the volume in mL per administration by the number of administrations per day
- Round the result to the nearest tenth
Using these steps, we get:
- (weight in kg) = (132) / (2.2) = 60 kg
- (dose in mg per administration) = (1) x (60) = 60 mg
- (volume in mL per administration) = (60) / (60 / 0.6) = 0.6 mL
- (volume in mL per day) = (0.6) x (2) = 1.2 mL
- (rounded volume in mL per day) = 1.2 mL
Therefore, the nurse should administer 1.2 mL of enoxaparin per day.
Correct Answer is ["18 mL\/hour"]
Explanation
To find the answer, we can use the following steps:
- Convert the client's weight from pounds to kilograms by dividing by 2.2
- Calculate the dosage of dobutamine in mg/hour by multiplying the weight in kg by the rate in mcg/kg/min and by 60
- Divide the dosage of dobutamine in mg/hour by the concentration of dobutamine in the solution in mg/mL
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (165) / (2.2) = 75 kg
- (dose in mg/hour) = (2) x (75) x (60) = 9000 mcg/hour
- (dose in mg/hour) = (9000 x 10^-3) = 9 mg/hour
- (volume in mL/hour) = (9) / (50 / 1000) = 180 mL/hour
- (rounded volume in mL/hour) = 18 mL/hour
Therefore, the nurse should set the infusion pump to deliver 18 mL/hour of dobutamine hydrochloride in D5W.
