db loss of a perforation of TM : 10-15db loss procedure done to fix perforation : tympanoplasty or myringoplasty monomeric spots : looks like a hole in TM, but reflects light like a mirror. holes that have healed. aka "mirror membranes" average dimentions of an adult eardrum : 2.3-2.9cm in length, .7cm in diameters pars tensa : lower 4/5 of TM and tight pars flaccida : upper 1/5 of TM and flaccid 2 | P a g e otis externa : "swimmers ear" - inflammation of the walls of the EAM...

The adult ear canal: - Rises upward and forward then descends to the drum The isthmus is: - Where the canal narrows to enter the temporal bone The pinna and the external canal together: - -Gather and reinforce accoustical signals -With the irregular shape of the auricle, cause increases and decreases at different frequencies as the sound arrives at the ear. -Forms a resonating tube. The average resonant frequency of the ear canal plus concha is: - 2700 Hz. The dividing line between the ex...

ATI MED SURG PROCTORED EXAM RETAKE (2022/2023) LATEST UPDATE WITH HIGHLIGTED SOLUTIONS .A nurse is assessing a client who is 12hr postoperative following a colon resection. Which of the following findings should the nurse report to the surgeon? 1. Heart rate 90/min 2. Absent bowel sounds → normal findings after major bowel surgery; takes several days to return to normal. 3. Hgb 8.2 g/dl 4. Gastric pH of 3.0 Rationale: Normal Hgb is 13-18M g/dl, 12-16 g/dl. This may indicate a possible hemorr...

Outer Ear - Pinna/auricle, ear canal, ear drum Middle Ear - Enclosed air-filled space, 3 bones and eustachian tube Inner Ear - Enclosed fluid-filled space, cochlea, auditory nerve Air Conduction - When sound travels through air; stimulates the outer, middle and inner ear. Air conduction tests use headphones Bone Conduction - When sound travels through the skull. Stimulates the inner ear directly. Why should you screen hearing in adults? - Identification and rehabilitation will minimiz...

Hearing Aid Dispenser-Hearing Disorders Latest Update with Complete Solutions The Air-Bone Gap is: Always better hearing by bone conduction than by air conduction, never the reverse. The Air-Bone Gap indicates: Impairment to the conductive portion of the hearing mechanism. Sensorineural Component What term describes the difference between the bone threshold and the range of normal hearing. (same as the loss by bone conduction)? Conductive Component What is the over-all differe...
