Which infection control measure, by the nurse, reduces the potential spread of methicillin-resistant Staphylococcus aureus (MRSA)?
Wearing an N95 mask while in the room of a patient with airborne precautions.
Wearing a facemask while in the room of a patient with droplet precautions.
Use of a separate disposable blood pressure cuff for any patient with a draining wound.
Use of strict hand washing measures once in every 8-hour work shift.
The Correct Answer is C
Choice A rationale
Wearing an N95 mask is appropriate for airborne precautions, such as tuberculosis, but not specifically for MRSA, which requires contact precautions.
Choice B rationale
Wearing a facemask is suitable for droplet precautions, such as influenza, but MRSA is primarily spread through direct contact, not droplets.
Choice C rationale
Using a separate disposable blood pressure cuff for patients with draining wounds helps prevent the spread of MRSA. MRSA can be transmitted via contaminated medical equipment.
Choice D rationale
Strict hand washing measures are essential but should be performed more frequently than once every 8-hour shift. Hand hygiene should be practiced before and after patient contact.

Choice B rationale
Viral infections can cause fever, but they typically do not lead to a significant increase in white blood cell count.
Choice C rationale
Fungal infections can cause fever and elevated white blood cell count, but they are less common and usually occur in immunocompromised individuals.
Choice D rationale
Parasitic infections can cause fever and elevated white blood cell count, but they are less common and usually present with other specific symptoms.
