Final answer:
The nurse should use b) surgical asepsis during airway suction to prevent contamination and minimize the risk of sepsis.
Step-by-step explanation:
The nurse should use b)surgical asepsis during airway suction.
Surgical asepsis involves a combination of protocols that maintain sterility to prevent contamination of sterile surfaces. This is important during airway suction procedures to minimize the risk of introducing microbes and causing sepsis. The nurse should follow strict procedures for creating a sterile field and using sterilized materials to ensure asepsis during airway suction.
