Final answer:
The error in the sequence for tracheostomy care is the suggestion to have a family member hold the tracheostomy tube, which should instead be done by a healthcare professional to maintain sterile technique.
Step-by-step explanation:
The incorrect step in the sequence for performing inline tracheostomy suctioning followed by tracheostomy tube care (using a disposable inner cannula) is found in choice D: Apply clean gloves. Remove the existing inner cannula. Insert the new inner cannula. Clean around the stoma and flange. Have another family member hold the tracheostomy tube.
The family member should not be advised to hold the tracheostomy tube as this task requires a professional with sterile technique to prevent infection. Instead, a trained member of the healthcare team should hold the tube securely in place during this care process.
