A client 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 ["12000"]
- To calculate the units of heparin in 12 hours, multiply the infusion rate by the concentration of heparin and the duration of infusion.
- Infusion rate = 25 mL/hour
- Concentration of heparin = 20,000 units / 500 mL
- Duration of infusion = 12 hours
- Units of heparin in 12 hours = 25 x (20,000 / 500) x 12
- Units of heparin in 12 hours = 12,000

Correct Answer is ["0.4"]
Explanation
To calculate the amount of methylprednisolone succinate that the child needs, we first need to multiply the child's weight by the prescribed dose. This gives us:
42 kg x 1.5 mg/kg/day = 63 mg/day
Since the medication is given in divided doses every 6 hours, we need to divide the daily dose by 4 to get the dose per administration. This gives us:
63 mg/day / 4 = 15.75 mg/dose
To convert the dose from mg to mL, we need to use the concentration of the medication, which is 40 mg/mL. This means that for every 1 mL of solution, there are 40 mg of methylprednisolone succinate. To find out how many mL are equivalent to 15.75 mg, we need to divide the dose by the concentration. This gives us:
15.75 mg / 40 mg/mL = 0.39375 mL
Since we need to round to the nearest tenth, the final answer is:
0.4 mL
Correct Answer is ["0.4"]
Explanation
To calculate the dosage, use the formula: D/H x Q = X
- D is the desired dose, H is the dose on hand, Q is the quantity, and X is the amount to administer
- Plug in the values: 240,000/1,200,000 x 2 = 0.4
- The nurse should administer 0.4 mL of penicillin G procaine
