Final answer:
To place additional sterile items on a sterile field, use sterilized forceps to handle materials and ensure all tools, like pipettes, are pre-sterilized. Always practice aseptic techniques to prevent contamination, such as flaming bottle openings and using sterile graduated pipettes for liquid transfers.
Step-by-step explanation:
When placing additional packaged sterile items on a sterile field, it's crucial to follow a step-by-step procedure to maintain an aseptic environment and prevent sepsis during medical procedures. Starting with sterilization, items such as forceps are cleaned with alcohol. These sterilized forceps are then used to handle materials like filter paper, inoculating loops, or antibiotic disks, placing them on a sterile field without contaminating them.
Pipettes often come pre-sterilized and should be handled with care to transfer sterile liquids accurately. It is essential to practice aseptic techniques by using pipette pumps and keeping the tube or bottle openings away from potential contaminants, such as passing them briefly through a flame before and after liquid transfer.
