A
Avoiding the use of disinfectants on surfaces
B
Frequent hand washing with soap and water
C

D
Using the same gloves for multiple patients
Verified step by step guidance1
Understand that Staphylococcus aureus is a common bacterium that can cause infections, especially in healthcare settings where it can spread easily from person to person or via contaminated surfaces.
Recognize that preventing the spread of Staphylococcus aureus involves breaking the chain of transmission, which often occurs through direct contact or via contaminated hands and surfaces.
Evaluate each practice: Avoiding disinfectants would increase risk, sharing personal items can transfer bacteria, and using the same gloves for multiple patients can spread pathogens between patients.
Identify that frequent hand washing with soap and water is a key infection control practice because it physically removes bacteria from the skin, reducing the chance of transmission.
Conclude that among the options, frequent hand washing with soap and water is the recommended practice to reduce the spread of Staphylococcus aureus in healthcare settings.
