Verified step by step guidance

Understand the importance of sterile technique: Sterile technique is crucial in minimizing infection risk during tracheostomy care because it prevents the introduction of pathogens into the tracheostomy site.

Recognize the difference between clean and sterile gloves: Clean gloves are used to protect the nurse from contamination, while sterile gloves are used to protect the patient from infection. Using sterile gloves is essential in maintaining a sterile field.

Identify the role of changing the tracheostomy tube: While changing the tracheostomy tube may be necessary for maintenance, it is not typically done daily and does not directly minimize infection risk compared to maintaining sterility during care.

Evaluate the use of antibiotic ointment: Applying antibiotic ointment may help prevent infection, but it is not a substitute for sterile technique. The primary focus should be on maintaining a sterile environment.

Implement sterile technique throughout the procedure: Ensure all equipment and materials used during tracheostomy care are sterile, and follow proper protocols to maintain sterility, such as using sterile gloves and avoiding contamination of the sterile field.
