Which statement made by the nurse would indicate an understanding of proper contact isolation precautions?

The statement indicating an understanding of proper contact isolation precautions is that a nurse can wear the same gown into rooms of patients with the same infection. This is because, in cases where patients have the same infection, the specific nature of that infection allows for the reuse of protective gowns within those designated patient spaces. This is practical and minimizes waste while still adhering to infection control measures.

This approach is based on the concept of transmission-based precautions, which focus on minimizing the risk of spreading infections that are transmitted in similar ways. By using the same gown for patients with the same infection, nurses can efficiently manage resources while still protecting themselves and other patients.

In contrast, it's vital for healthcare providers to follow stringent hand hygiene protocols, as indicated in other statements. Washing hands before and after entering patient rooms is crucial for preventing cross-contamination. Reusing gloves between patients is generally not acceptable because it can lead to the spread of pathogens. Similarly, wearing a mask at all times may not be necessary depending on the type of contact precautions in place; it is typically reserved for specific situations where respiratory protection is indicated, rather than contact isolation.
