C.    Proper disposal of sharps: Proper disposal of sharps is important to prevent needlestick
injuries and transmission of bloodborne pathogens but does not represent a reservoir of infection.
D.    A contaminated surface: A contaminated surface can serve as a reservoir for infectious agents.

Explanation

  • Place the client in a private room.
    • Essential: Placing the client in a private room helps prevent the spread of MRSA to other patients and reduces the risk of transmission.
  • Administer intravenous vancomycin.
    • Essential: Vancomycin is an appropriate antibiotic choice for treating MRSA infections, and administering it intravenously allows for effective delivery of the medication to combat the infection.
  • Wear a cover gown when caring for the client.
    • Essential: Wearing a cover gown provides an additional barrier of protection against potential contact with the client's infected wound and helps prevent transmission of MRSA to healthcare workers and other patients.
  • Restrict fluid intake.
    • Contraindicated: Restricting fluid intake is not indicated in this scenario. Adequate hydration is essential for supporting the body's immune response and maintaining organ function, especially in the presence of fever and infection.
  • Initiate supplemental oxygen.
    • Nonessential: Supplemental oxygen is not indicated based on the client's oxygen saturation of 96% on room air. Oxygen supplementation is typically reserved for clients who are hypoxic or experiencing respiratory distress, which is not the case here.
