Infants: when does inner ear development take place?
1st trimester
Why are infants and children prone to ear infections as opposed to adults?
-external auditory canal is shorter
-eustachian tube is wider, shorter, and more horizontal
What causes pregnant women to appear congested?
elevated estrogen causes...
-increased vascularity of URT
-capillaries engorge in E,N,T
T or F in Older Adults: Sensorineural hearing loss first occurs with high-frequency sounds and then progresses to tones of lower frequency
T
Deterioration of the sense of smell results from loss of olfactory sensory neurons beginning at what age?
A. 40
b. 50
C. 60
D. 70
C. 60 y/o
Choose all that apply: The sense of taste begins deteriorating at about 50 y/o because...
A. the number of papillae on the tongue increases
B. salivary gland secretion decreases.
C. # of papillae decreases
D. loss of teeth
b, c
What does xerostomia mean?
A. Stoma development in the parotid gland
B. Cyst on external auditory canal
C. Dry mouth
c
Which infant fontanel is diamond shaped?
anterior
Which infant fontanel is triangle shaped?
posterior
Which hearing test(s) are used for bone and conduction?
A. shouting test
B. Rinne
C. whisper test
D. Weber
b
T or F
A normal Rinne test is Bone conduction is greater than Air conduction?
-False. Normal is Air>bone conduction; should be a 2:1 ratio.
- Conductive hearing loss=bone conduction heard longer than air in affected ear
- sensorineural hearing loss= air>bone in affected ear BUT IS LESS THAN 2:1 ratio
What shape does infants typanic membrane become after a few weeks of life?
A. Round
B. Diamond
C. Cone
D. Oblong
C.Cone
To test bone conduction with the Rinne Test, what bone do you place the tunning fork?
A. Frontal bone
B. Mastoid
C. Ethmoid
D. Malleus
Mastoid
T or F
Using an otoscope on an adult, you straighten the external auditory canal by pulling auricle up and back
True.
Children- pull auricle down to view tympanic membrane
Choose all that apply:
Age-related hearing loss is associated with degeneration of:
A. Corti hair cells
B. cortical and Corti auditory neurons
C. cochlear conductive membrane
D. Decreased vascularization of the cochlea
all of the above
Choose all that apply:
Conductive hearing loss may result from..
A.Excess deposition of bone cells along the ossicle chain
B. Ear wax (cerumen)
C. Upper Resp Infections
D. Sclerotic tympanic membrane
A,B,D
What oral changes occur in older adults?
-Dry mouth
-Loss of teeth
-Difficulty Chewing
-Difficulty Swallowing r/t altered motor function of tongue
Which will decrease salivation?
A. Beta Blockers
B. IVF
C. Anticholinergics
c
Cranial Nerve V is called?
A. Optic
B. Trigeminal
C.Hypoglossal
D. Facial
B
How can you test CN V?
A penlight, pupils constrict
B Chew a piece of food
C. Stick out tongue
D. Ask pt to smile, symmetry
b
What is CN VII called?
A. Optic
B. Trigeminal
C. Hypoglossal
D. Facial
D
How can you test CN VII?
A penlight, pupils constrict
B Chew a piece of food
C. Stick out tongue
D. Ask pt to smile, symmetry
D
Weber test is used for?
A. Bone Conduction
B. unilateral hearing loss
C. Air Conduction
B
-Expected finding: no lateralization.
-Conductive hearing loss=lateralization of affected ear
-sensorineural hearing loss=lateralization to better ear
Where is the tuning fork placed in the Weber test?
A. Mastoid bone
B. Left ear 1st
C. right ear 1st
D. midline (ontop) of head
