Final answer:
Persons in sterile attire should pass each other back to back to minimize contamination and maintain aseptic technique. Other important measures include strict hand hygiene and the disinfection of surfaces and equipment.
Step-by-step explanation:
In the context of health care and sterile environments, it is crucial to maintain aseptic technique to prevent the spread of infection. When two persons in sterile attire need to pass each other, the recommended method is to pass back to back. This minimizes the risk of contamination, as the most contaminated area (the front of the body) is kept away from the sterile areas of the other individual. Other measures such as stringent hand hygiene practices, the careful disinfection of all items, and personal protective clothing are also essential to maintain a sterile field in healthcare settings.
