Kim is instructed to perform a bilateral ear irrigation on a 68-year-old patient with impacted cerumen. Before the procedure, she uses an otoscope to check the auditory canal and sees a large amount of dark brown cerumen in the right ear, completely covering the tympanic membrane. The left ear has a moderate amount of golden-brown cerumen covering the bottom half of the tympanic membrane. After the procedure, both membranes are visible, and the patient tolerated the procedure without complaints.
