Ear Assessment Ch. 16 NURS 319 Dr. Trina Kumodzi 1 Objectives 1. Describe the pertinent subjective data related to the ear system. 2. Demonstrate examination technique for the ear system. 3. Interpret assessment findings of the ear system. 4. Accurately document the findings of the ear system. 5. Analyze subjective and objective data to develop nursing care. 6. Describe nursing diagnoses common to the ear system. 2 Ear Anatomy 3 Ear Anatomy • External Canal • Cerumen – Protect and lubricate the ear • Tympanic Membrane • Translucent membrane with a pearly gray color • Separates external and middle ear • Oval and slightly concave, pulled in at its center by one of middle ear ossicles, the malleus 4 Hearing • CN VIII • Hearing loss – Anything obstructing transmission of sound 5 Hearing • Conductive hearing loss involves a mechanical dysfunction of external or middle ear – impacted cerumen – foreign bodies – perforated TM – pus or serum in middle ear – decrease in mobility of ossicles • otosclerosis 6 Hearing • Sensorineural (or perceptive) hearing loss signifies pathology of inner ear, cranial nerve VIII, or auditory areas of cerebral cortex – presbycusis • Mixed hearing loss is combination of conductive and sensorineural types in same ear 7 Equilibrium • Labyrinth in inner ear – works like a plumb line to determine verticality or depth – register angle of your head in relation to gravity 8 Developmental Competence: Infants and Children • Inner ear develops during 1st trimester • An infant’s Eustachian tube is wider, shorter, and more horizontal than in adults • Increase risk for nasopharyngeal reflux 9 Developmental Competence: Adult • Gradual hardening that causes foot plate of stapes to become fixed in oval window • Impeding transmission of sound and causing progressive deafness 10 Developmental Competence: Adult • Aging adult – Conductive loss • High-tone frequency – Gradual nerve degeneration (Presbycusis) – Auditory reaction time 11 Subjective Data Pain Discharge Trouble hearing Tinnitus – ringing, crackling, or buzzing in your ears • Vertigo – room is spinning around or feel that you are spinning? • • • • 12 Subjective Data • Use of hearing device • Environmental noises at home and on the job • Self care behaviors – Cleaning the ear, hearing test 13 Note to Examiner • During history, notice clues from normal conversation indicating possible hearing loss – Lip reading or watching your face and lips rather than your eyes – Frowning or straining forward to hear – Posturing of head to catch sounds with better ear 14 Note to Examiner – Misunderstands questions; frequently asks you to repeat – Irritable or shows startle reflex when you raise your voice – Person’s speech sounds garbled, vowel sounds distorted – Inappropriately loud voice – Flat, monotonous tone of voice 15 Additional History for Infants and Children • Have you noticed that infant: – startles with loud noise? – babble around 6 months? – What age was the child when they started talking? Was speech intelligible? • Did the child have a hearing test? 16 Additional History for Infants and Children • It is important to catch any problem early – hearing loss delays speech, social development and learning. 17 Inspection • Size, shape, and symmetry ‒ Ears are of equal size bilaterally with no swelling or thickening ‒ Ears of unusual size and shape may be a normal familial trait with no clinical significance • Skin intact 18 Palpation • Tenderness of pinna and tragus • Palpate mastoid process • Mastoiditis, untreated otitis media 19 The Otoscopic Exam 20 Otoscopic Examination • Otoscope funnels light into ear canal onto tympanic membrane • Tilt head slightly away from you toward patient’s opposite shoulder • Pull the pinna upward and back (for an adult) as speculum is inserted • Insert no more than 1/2 inch • Note color, contour, discharge, foreign bodies, and cerumen 21 22 Tympanic Membrane (TM) Right Ear 23 Assess for Hearing Loss (CN VIII): Voice test • Stand approximately 1-2 feet from client and instruct client to cover opposite ear • Whisper a set of 3 random number or letters (7, A, 4). • Repeat procedure in another ear • Person should respond correctly at least 50% of time 24 Hearing Acuity for Infant and Children • Birth-3mos: startle (Moro) reflex, crying, cessation of breathing or movement to sudden noise, calm to parent’s voice • 4-6mos: turns head to sounds; responds to parent’s voice; enjoys sound producing toys • 6-10 mos: responds to name, telephone ringing, and voice • 10-12mos: recognizes and localizes source of sound; imitates simple words and sounds 25 Developmental Consideration for Aging Adult – Eardrum may be whiter in color and more opaque, duller and thicker than in younger adult 26 Sample Charting: Subjective 27 Sample Charting: Objective 28 Sample Charting: Assessment 29 Practice Question #1 During a hearing assessment, the nurse notes that the sound lateralizes to the clients left ear with the Weber test. The nurse analyzes this result as: A. A normal finding B. A conductive hearing loss in the right ear C. A sensorineural or conductive loss D. The presence of nystagmus 30 Answer to Question #1 w/ Rationale C. A sensorineural or conductive loss Rationale: In the Weber tuning fork test the nurse places the vibrating tuning fork in the middle of the client's head, at the midline of the forehead, or above the upper lip over the teeth. Normally, the sound is heard in equally in both ears by bone conduction. If the client has a sensorineural hearing loss in one ear, the sound is heard in the other ear. If the client has a conductive hearing loss in one ear, the sound is heard in that ear. 31 Practice Question #2 The nurse would question an order to irrigate the ear canal in which of the following circumstances? A. Otitis externa B. Perforated tympanic membrane C. Hearing loss D. Ear pain 32 Answer to Question #2 w/ Rationale B. Perforated tympanic membrane Rationale: Irrigating a perforated tympanic membrane is contraindicated because it will further damage the already damaged eardrum. This may result in permanent hearing loss. 33
