Step-by-step explanation:
The nursing staff should prioritize diligent handwashing practices and constant use of gloves when on the unit in order to prevent the spread of MRSA to clients who are currently MRSA-negative. These measures are crucial in reducing the transmission of bacteria from contaminated surfaces and equipment to patients. Prophylactic antibiotic therapy for MRSA-negative clients is not recommended as a preventive measure, and reducing the length of stay for MRSA-positive clients does not directly address the prevention of transmission.
