|
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 |
d
