Final answer:
To administer a 75 mg dose of Solu-Medrol from a concentration of 125 mg/2 ml, you would give 1.2 ml of the solution.
Step-by-step explanation:
The question involves calculating the volume of Solu-Medrol solution to be administered based on the given concentration. Since the physician has ordered 75 mg IV of Solu-Medrol and after reconstitution you have a Solu-Medrol solution of 125 mg/2 ml, you need to determine how many milliliters contain the 75 mg dose. To do this, you can use the proportion:
125 mg / 2 ml = 75 mg / x ml
By cross-multiplying and solving for x, you find:
125x = 75 * 2
125x = 150
x = 150 / 125
x = 1.2 ml
Therefore, to administer a 75 mg dose, you would give 1.2 ml of the reconstituted Solu-Medrol solution.
