Final answer:
The nurse should use the dilution technique to mix the linezolid.
Step-by-step explanation:
The nurse should use a technique called dilution to mix the linezolid. Dilution involves combining a more concentrated solution with a sterile solution to achieve the desired concentration. In this case, the nurse would use a syringe to draw up the stock solution of linezolid and inject it into an IV bag containing sterile solution, diluting it to the proper concentration.
