study guide 3 Flashcards
______is a record of a person’s background info, hearing history obtained at the initial appointment; first contact you have with patients where you find out where they feel that they have problems
case history
case history should contain 5 major components
demographics hearing and balance concerns otologichistory medical background medications
questions one can ask during a case history
when was the symptom first noticed?
how severe is the symptom?
is the symptom present in one or both ears?
has the symptom improved or worsened over time?
is the symptom constant or intermittent?
ringing in the ears ; internally generated sound which is perceived as originating from one or both ears
tinnitus
one ear may or may not be worse than the other
hearing loss
ear pain
otalgia
discharge
otorrhea
spinning sensation (dizziness imbalance )
vertigo
what usually causes tinnitus ?
hearing loss or noise exposure
rushing associated with vascular event on or around the ear
pulsatile
nonpulsatile refers to
ringing
the visual inspection of the pinna mastoid process, the EAM, and the tympanic membrane
otoscopyis
during an otoscopy one uses an
otoscope
-always go with the larger tip
3 parts of the otoscope
the handle- power for the light source
the head- lightbulb and magnifying lenses
the cone- specula
for adult otoscopy one pulls the pinna ___ and _____
up and back to straighten the EAC
for children one pulls the pinna _____ and _____
down and back to the straighten the EAC
labels for the cerumen
occluding, excessive, minimal,none
in evaluating the tympanic membrane….. one should make sure it is
light grey, pink, and very shiny
the cone of light should be easily visible
notice if any air fluid lines, bubbles, and retractions are visible
what is the purpose of pure tone testing?
to determine the type, extent ( severity), and configuration of a patient’s hearing loss
what is the goal of air conduction audiometry?
to determine the amount, degree, or severity of the hearing loss.
- how severe is the hearing loss?
- is a hearing loss present?
what is the special number?
5
what is the goal of bone conduction audiometry?
to determine the type of hearing loss present
what are the types of hearing loss
conductive
sensorineural
mixed
what is the transducer used to perform bone conduction
the bone oscillator
the bone conduction pathway bypasses the outer and middle ear and directly stimulates the ________
cochlea
AC one uses the
headphones, inserts, speakers
BC one uses the
bone oscillator
we plot responses using an
audiogram
the x axis of an audiogram measures
frequency 250- 8000 Hz
the y axis of an audiogram measures
intensity from -10db HL to 110dB HL
softest level the patient is able to hear a tone
threshold
bone conduction label is
the degree or severity of the Hearing loss can be described in what categories?
Slight Mild moderate Moderately severe Severe Profound
what denotes conductive hearing loss ?
normal BC scores
Abnormal AC scores
ABG of 15 dB or Greater
issues exist with either the outer ear, middle ear, or both
what is the ABG?
the Air bone gap or the gap between the AC threshold and BC threshold
what denotes sensorineural hearing loss ??
abnormal BC scores
Abnormal Ac scores
No ABG
Issues exist in the inner ear and or beyond (auditory nerve, brainstem)
what denotes mixed hearing loss ??
abnormal BC scores
Abnormal AC scores
ABG present
Issues exist with OE/ME and inner ear/ beyond
what is the configuration of hearing loss??
the overall shape of the audiogram
ways to describe configuration?
Flat
Sloping
steeply Sloping
noise notch (typically at 4000 Hz)
