Choice A rationale:

Performing tracheostomy care every 2 to 4 hours would be too frequent for most patients and may cause unnecessary disruption and discomfort. This interval is not the recommended standard of care.

Choice B rationale:

Tracheostomy care every 4 to 6 hours strikes a balance between maintaining airway hygiene and minimizing excessive handling of the tracheostomy site, reducing the risk of complications such as infection or irritation.

Choice C rationale:

Waiting to perform tracheostomy care every 6 to 8 hours may increase the risk of mucus buildup and potential complications, especially in patients with high secretions or respiratory issues.

Choice D rationale:

Extending the interval to every 8 to 12 hours may lead to inadequate airway clearance and increased risk of complications in patients who require more frequent care.

Choice E rationale:

Waiting to perform tracheostomy care every 12 to 24 hours is too infrequent for most patients and may not be sufficient to maintain a patent airway and prevent complications.
