Q

What is the route for the meninges and the inner ear

A

Perilymphatic duct - allows route of communication bw meninges and inner ear
Perilymph and csf are very similar in makeup
Endolymphatic duct & sac - absorb from inner ear up to the dural space of the extra endolymph

Q

What does stria create to allow organ of corti to work

52
Q

Hospital-grade disinfectants, like Audiologist’s Choice solution or Cavicide wipes

A

High-level disinfection

53
Q

Surfaces like chairs and counter tops during everyday encounters with patients should be:

A

Cleaned
Disinfected

54
Q

First step. Removes gross (visible) contamination from the surface

A

Clean

55
Q

Kills some of the germs, but not all of them

A

Disinfect

56
Q

Kills 100% of the germs 100% of the time

A

Sterilize

57
Q

Whenever we may have contact with potential infectious material
If risk of cerumen, blood, splatter, wear protection

A

PPE

58
Q

method for removing cerumen:

A

irrigation, mechanical insrumentations (forceps, curette (loop), scoops etc.), suction,

59
Q

If you see it in the ear, how do you know when to remove it?

A

Blockage of ™, to prevent pushing it in further (interference of treatment or procedure), if it is dry/hard and won’t come out on its own

60
Q

What are precautions/contraindications for doing cerumen

A

perf do not irrigate (always do tymps and otoscopy before doing irrigation), diabetes (infection, they do not heal as good), blood thinners (in case they bleed and we know how to treat it), PT consent (gone over questions and precautions and they consent to having it done)

61
Q

Why do we have cerumen?

A

Lubricate - keeps it moist so it isnt dry and itchy
Protect - barrier to catch things
Migrates out as epithelial migration so when it catches those things it will fall out and you wont even know it

62
Q

What agency created the Universal Blood and Bloodborne Pathogen Precautions, also known as Standard Precautions?

A

cdc

63
Q

64
Q

first sign of nervous system forming is a thickening of groove in ectoderm that becomes

A

Someone with a liberal criterion will present with relatively better or poorer hearing thresholds. Why?

A

better because they have a higher tendency to say yes

Someone with a conservative criterion will present with relatively better or poorer hearing thresholds. Why?

A

poorer because they have a higher tendency to say no and wait until it gets louder
