A client with deep vein thrombosis (DVT) is receiving a continuous IV 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 ["12000"]
Here's how to calculate the total heparin units the client will receive in 12 hours
Heparin concentration:
The medication is delivered in a 500 mL bag containing 20,000 units of heparin.
Heparin concentration (units/mL) = Total heparin (units) / Volume (mL)
Heparin concentration (units/mL) = 20,000 units / 500 mL
Heparin concentration (units/mL) = 40 units/mL
Infusion rate: 25 mL/hour (given)
Time: 12 hours (given)
We need to find the total number of heparin units delivered in 12 hours.
Total volume delivered in 12 hours:
Volume delivered (mL/hour) x Time (hours) = Total volume delivered (mL)
25 mL/hour x 12 hours = 300 mL
Total heparin units delivered:
Heparin concentration (units/mL) x Total volume delivered (mL) = Total heparin units
40 units/mL x 300 mL = 12,000 units
Therefore, the client will receive 12,000 units of heparin in 12 hours.

Correct Answer is ["0.5"]
Explanation
Here's how to calculate the volume of heparin the nurse should administer:
1. Heparin dose: 5,000 units (given)
2. Heparin concentration: 10,000 units/mL (given on the vial label)
We need to find the volume (mL) containing the prescribed dose (5,000 units) of heparin.
Calculation:
Volume to administer (mL) = Dose (units) / Concentration (units/mL)
Volume to administer (mL) = 5,000 units / 10,000 units/mL
Volume to administer (mL) = 0.5 mL (round to nearest tenth as requested)
Therefore, the nurse should administer 0.5 mL of heparin.
Correct Answer is ["2000"]
Explanation
Here's how to calculate the total milligrams of ampicillin the child should receive per day:
Convert child's weight to kilograms:
Weight (kg) = Weight (lbs) / Conversion factor (lbs/kg)
Weight (kg) = 88 lbs / 2.205 lbs/kg
Weight (kg) = 40 kg (round to nearest whole number)
Calculate the total daily dosage:
Daily dosage (mg) = Dose per kg (mg/kg/day) * Weight (kg)
Daily dosage (mg) = 50 mg/kg/day * 40 kg
Daily dosage (mg) = 2000 mg
Therefore, the child should receive 2000 mg of ampicillin per day.
