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 ["1.2"]
- Calculate the amount of solution needed to provide 150 mg of hydrocortisone sodium succinate
- Use the formula: D/H x Q = X, where D is the desired dose, H is the dose on hand, Q is the quantity on hand, and X is the amount to administer
- Plug in the values: 150/250 x 2 = 1.2
- Round to the nearest tenth: 1.2 mL
- Administer 1.2 mL of the reconstituted solution intravenously STAT

Correct Answer is ["15"]
Explanation
- Calculate the daily dose of amoxicillin for the child: 80 mg/kg/day x 66 pounds / 2.2 pounds/kg = 2400 mg/day
- Divide the daily dose by the number of doses per day: 2400 mg/day / 2 doses/day = 1200 mg/dose
- Convert the dose from mg to mL using the label information: 1200 mg/dose x 5 mL/400 mg = 15 mL/dose
- The nurse should administer 15 mL of amoxicillin with each dose.
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
