While caring for a patient scheduled for knee replacement surgery, the nurse provides cefazolin(antibiotic) as ordered 30 minutes preoperatively. Which statement indicates that teaching has been effective?

A. "This medication will replace vitamins and minerals that may be lost due to bleeding during surgery." Cefazolin is an antibiotic, not a replacement for vitamins and minerals. This statement is incorrect. B. "This is a palliative medication to help ease the pain from surgery."Cefazolin is not a palliative medication; it is an antibiotic used to prevent infection, not to relieve pain. C. "This medication will help the surgeon identify areas of bone destruction due to arthritis." Cefazolin does not aid in the identification of bone destruction. It is an antibiotic, not a diagnostic tool. D. "This antibiotic is given as a prophylactic to help reduce the risk of infection after surgery." This statement is correct. Cefazolin is given prophylactically to reduce the risk of postoperative infection.
