A client with purulent drainage from an abdominal surgical incision is admitted with a possible vancomycin-resistant enterococci (VRE) infection. Which nursing intervention(s) should the nurse include in the plan of care? Select all that apply.

A. A low bacteria diet is not typically indicated unless the client is severely immunocompromised, which is not stated in this scenario. B. Standard precautions are always required, but a mask is not specifically necessary unless there is a respiratory concern; contact precautions are more critical in this context. C. Sending wound drainage for culture and sensitivity is essential for diagnosing the infection and guiding treatment. D. Monitoring the white blood cell count is important to assess the client's response to infection and treatment. E. Instituting contact precautions is crucial to prevent the spread of VRE to other patients and healthcare workers.
