Q

how can the referral source provide a clue to patient management approaches?

A

it can give insight on who has noticed there could be HL
-self referral or referral from family member leads to them being aware of communication needs
-physician referral means a medical diagnosis or management

Q

advantages for a oral case history

A

establishes rapport with patient, establish environment where the patient feels his/her needs are met, allows for the asking of clarification questions, and estimate cognitive level and hearing level to guide instruction

Q

what does a normal otoscopic examination report look like?

A

Upon otoscopic examination, both pinnas appear fully formed and there are no abnormalities on the pinnas or the area around. The tympanic membrane appeared semi-translucent with normal shape. Cone of light is present in both ears and the umbo and landmarks of the malleus are visible. No abnormalities present in either ear.

23
Q

3 components of EBP

A

evidence (external and internal), clinical expertise, and client perspective

24
Q

what are the 3 highest levels of evidence?

A

systematic review, randomized control study, and cohort study

25
Q

are lower levels of evidence valuable?

A

yes, sometimes that is all that is available

26
Q

RETSPL

A

reference equivalent threshold sound pressure level
-what we use to go from dB SPL to dB HL

27
Q

why is there a different RETSPL value for different transducers?

A

there are different volume sizes between the membrane and the headphone

28
Q

dB SPL to dB HL

A

dB SPL - RETSPL
dB HL + RETSPL

29
Q

if your headphone stops working, can a different headphone of the same type be plugged in and still have valid testing?

A

this will not be a valid testing, as it invalidates the calibration
-can do this to troubleshoot but not for valid testing

30
Q

dB SL

A

sensation level
-presentation minus threshold

31
Q

biologic calibration

A

daily check to ensure equipment is working properly

32
Q

how to check frequency switch

A

within daily bio-checks : switch between frequencies to ensure they are changing

33
Q

how to check attenuation dial

A

within daily bio-checks : scroll with the dial and ensure the presentation level is changing

34
Q

how to check cross talk

A

within daily bio-checks : place on headphone on the ear and the other on the forehead of behind ear and present tone to the headphone NOT on ear
-ensure there is no sound coming through the headphone on ear

35
Q

how to check integrity of the cord

A

within daily bio-check : as tone’s are being presented move the cords around to ensure there is not static or unwanted noise

36
Q

what is the cross-check principle

A

the idea that no auditory test should be accepted and used in the diagnosis of HL until it is confirmed or cross checked by one or more independent measures
-using another test to verify results of a different test

37
Q

speech recognition threshold (SRT)

A

testing for the softest level a person can repeat words at 50% of the time
-using spondaic words
-speech reception threshold or spondee threshold

38
Q

spondaic words (spondee words)

A

two syllables with equal stress on each one

39
Q

what is the primary clinical use of SRT?

A

cross check principle

40
Q

what is the secondary usage of SRT?

A

baseline for determining supra threshold speech testing level

41
Q

materials used for SRT

A

recorded materials or live voice speech
-use recorded in a patient’s native language and have a list of those words

42
Q

SRT procedure

A

-inform patient on the task at hand
-start the presentation at 30 dB HL
-for correct respond down 10 dB
-for no/wrong response up 5 dB
-continue this process until 2/4 correct responses are received in an ascending run

43
Q

pure tone average (PTA)

A

pure tone average
-average of 500, 1000, and 2000 Hz

44
Q

fletcher PTA

A

pure tone average of the two best thresholds out of 500, 1000, and 2000
-ex. if we have a 30, 50, and 65 dB at those frequencies, we would average out 30 and 50

45
Q

dB level difference for SRT and PTA to be considered in good agreement

A

6 dB or within 5 dB to 10 dB

46
Q

how should an SRT be measured if the patient is not a native speaker of english

A

using a recorded voice

47
Q

speech detection threshold/speech awareness threshold (SDT/SAT)

A

testing for the softest level a person can detect speech at 50% of the time
-no repetition of words

48
Q

how is SAT/SDT measured

A

by presenting words and having the patient signal if they heard it or not
-presenting CD recorded voice ideally
-using same procedure as SRT

49
Q

dB level difference for SAT/SDT and PTA to be considered in good agreement

A

15-20 dB

50
Q

RETSPL values for speech for supra-aurals and inserts

A

20 dB supra-aurals
12.5 dB for inserts

51
Q

what frequencies should be tested per ASHA 2005

A

1000, 2000, 3000, 4000, 6000, 8000, retest 1000, 250, 500

52
Q

when would you test interoctave frequencies that are not part of the standard test

A

if there is a 20 db difference between 2 adjacent frequencies

53
Q

when doing puretone testing, which ear should be tested first

A

the better ear

54
Q

which frequency should be tested first for puretone testing

A

1000 Hz

55
Q

important factors for sound field testing

A

present through the speaker on their better ear side,nothing on the wall between the patient and speaker, place patient on the marker on the ceiling or floor, should be equal distance between two speakers

56
Q

how to interpret sound field testing

A

when stating within a report, it must be stated as “________ limits at least within one ear”
-since it is being presented in the speaker on the better ear side, we do not know exactly if the other ear is picking it up or not

57
Q

why is it necessary to calibrate each CD every time you change discs?

A

each CD is different
