A client receives a prescription for hydrocortisone sodium succinate 150 mg intravenously STAT. The powdered medication needs to be reconstituted with 2 mL of bacteriostatic water that will provide a solution of 250 mg/mL. How many mL should the nurse administer?
(Enter numerical value only.)
The Correct Answer is ["0.6"]
The prescription is for hydrocortisone sodium succinate 150 mg, reconstituted to a concentration of 250 mg/mL using 2 mL of bacteriostatic water.
The total amount after reconstitution:
150 mg ÷ 250 mg/mL = 0.6 mL
The nurse should administer 0.6 mL of the reconstituted solution.

Correct Answer is ["0.4"]
Explanation
To calculate the amount of methylprednisolone succinate the child receives with each dose, we need to divide the daily dose by the number of doses per day and then divide by the concentration of the medication.
The daily dose is 1.5 mg/kg/day, the number of doses per day is 4 (every 6 hours), and the concentration of the medication is 40 mg/mL. Therefore, the amount of methylprednisolone succinate is:
(1.5 mg/kg/day x 42 kg) / 4 / 40 mg/mL = 0.39 mL
The nurse should administer 0.4 mL (rounded to the nearest tenth) with each dose.
Correct Answer is ["168"]
Explanation
First, convert pounds to kilograms:
185 lbs × 0.453592 kg/lb ≈ 83.91 kg
Now, calculate the dosage:
Dosage = 2 mg/kg × 83.91 kg ≈ 167.82 mg ≈ 168 mg
The nurse should prepare approximately 168 mg of zidovudine for administration based on the client's weight.
