- D225 ml
Show answer & explanationAnswer & explanation
Correct answer: D. 225 ml
To find the total volume, simply add the volumes of the two components. 150 ml + 75 ml = 225 ml.
Why the other options are wrong
- A. This is only the volume of the saline solution, not the total.
- B. This is double the saline solution volume; incorrect.
- C. This is only the volume of the medication, not the total.
