A client with foul-smelling drainage from an incision on the upper left arm is admitted with a suspected methicillin-resistant Staphylococcus aureus (MRSA). What nursing intervention(s) should the nurse include in the plan of care? Select all that apply.

A. Contact precautions are essential to prevent the spread of MRSA to other patients and healthcare workers. This includes wearing gloves and gowns when entering the patient's room. B. A low bacteria diet is not specifically relevant to managing MRSA and is more applicable to neutropenic patients. C. Monitoring the white blood cell count helps in assessing the client's response to infection and identifying any potential systemic involvement. D. Sending wound drainage for culture and sensitivity is crucial for identifying the specific strain of MRSA and determining the most effective antibiotic treatment. E. Standard precautions are always necessary, but a mask is not required unless there is a risk of splashing or the patient has a respiratory infection.
