Amber is a 25-year-old college student who recently broke her leg, both the tibia and fibula, while snowboarding. She had extensive surgery to fix her broken bones but is still experiencing quite a bit of pain. It has been only two weeks since she had her surgery, and she is wondering if the medications the doctor gave her are strong enough to help relieve her pain. In discussing her care, Amber mentioeneSSns that she takes the medication only when she is experiencing pain but then she still has pain for several hours before the medication starts to help. What information would you give Amber to help her with her pain management?
