Which of the following practices helps reduce the risk of infection during a procedure?

Wearing gloves is a critical practice that significantly helps reduce the risk of infection during medical procedures. Gloves serve as a barrier between the healthcare provider and the patient, preventing the transmission of pathogens that can lead to infections. They protect both the healthcare worker from exposure to blood, bodily fluids, and potential pathogens, and the patient from microorganisms that may be present on the worker's hands. This practice is part of standard precautions in infection control and is essential in maintaining a safe environment for both practitioners and patients.

In contrast, using shared instruments poses a risk of cross-contamination and infection, as these instruments can transmit pathogens from one patient to another if not properly sterilized. Having an open wound increases the risk of infection, both for the person with the wound and for others, as it provides a direct entry point for pathogens. Lastly, working in a cluttered environment can lead to increased chances of contact with contaminated surfaces or instruments, making it easier for infections to spread. Thus, wearing gloves is undeniably one of the most effective practices for minimizing infection risk during procedures.
