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 ["6"]
Explanation
- To calculate the infusion rate, use the formula: infusion rate (mL/h) = dose (units/h) x volume (mL) / concentration (units)
- In this case, the dose is 2 milliunits/min or 0.12 units/h
- The volume is 1000 mL and the concentration is 20 units
- Plug in the values and simplify: infusion rate = 0.12 x 1000 / 20
- The infusion rate is 6 mL/h
- The nurse should program the pump to deliver 6 mL/h
Correct Answer is ["15"]
Explanation
- Calculate the volume to be infused: 630 mL
- Calculate the time of infusion in minutes: 7 hours x 60 minutes = 420 minutes
- Calculate the infusion rate in mL/minute: 630 mL / 420 minutes = 1.5 mL/minute
- Calculate the infusion rate in drops/minute: 1.5 mL/minute x 10 gtt/mL = 15 gtt/minute
- The nurse should regulate the infusion to deliver 15 drops/minute
