Final answer:
A sterile person faces a nonsterile person when passing to proper aseptic techniques should be followed to minimize the risk of transferring contaminants.
Step-by-step explanation:
When a sterile person faces a nonsterile person while passing, there is a risk of transferring contaminants from the nonsterile person to the sterile person. To minimize this risk, it is important to follow proper aseptic techniques. For example, when passing the opening of a tube or bottle, it should be held at an angle to minimize the potential for airborne contaminants to enter. Additionally, briefly passing the opening through a flame before and after the transfer process can discourage airborne contaminants from entering the sterile liquid.
It is also important to practice proper pipetting techniques. Before attempting to pipette a sterile liquid, it is recommended to practice with water. This includes drawing up and releasing water in small increments to get comfortable with using the pipette. Aseptic techniques should be followed when practicing with water in a capped media bottle as well.
So therefore when a sterile person faces a nonsterile person during passing, proper aseptic techniques should be followed to minimize the risk of transferring contaminants. This includes holding tubes or bottles at an angle and passing the opening through a flame. Practice with water can help improve pipetting techniques and aseptic practices.
