RN HESI Dosage Calculations II Proctored Exam
Calculation
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.)
mL
Explanation & Rationale
- 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
