A nasal-cannula pressure injury of the nares, columella, or behind the ears → offload and treat; notify (cross-reference Wounds).
Facial swelling and redness from a sinus source, with fever → possible facial cellulitis; notify urgently.
New unilateral obstruction with bloody drainage or a mass → evaluate; notify.
