Question 6

What cannot be assessed through nasometry?

A)Resonance
B)Upper airway obstruction during speech
C)Changes in resonance following surgery

B)About 5%
C)About 10%
D)About 15%
E)About 20%

Question 8

What does a high nasalance score indicate?

C)Hypernasality
D)Hyponasality
E)Cul-de-sac resonance

Question 9

What is the advantage of using a standardized passage to gather nasometric data?

A)The passage can be read by the individual rather than repeated.
B)It is easier to administer because it is well-known by the examiner.
C)The patient's score can be compared to normative data.
D)The passage is designed to contain only certain sounds to make it easier to produce.
E)The passage can be designed to contain only oral sounds.

Question 10

Which of the following is not true about nasometry?

A)It is an indirect measure.
B)It provides objective data regarding resonance.
C)It can be used with connected speech.
D)It provides a visual representation of resonance in real time.
E)It provides direct visualization of the velopharyngeal valve.

Question 11

Which of the following tests allows the assessment of nasalance by type of speech sound?

A)Zoo Passage
B)Nasal Sentences
C)SNAP test

E)Turtle Passage

Question 12

Which of the following is not true about interpretation of nasalance?

A)Normal oral resonance is typically under 20 percentage points.
B)If lingual-alveolars and bilabials are significantly higher than velars, this could be due to an oronasal fistula.
C)Articulation errors can affect the nasalance score.
D)The higher the contour is on the screen, the more hyponasality to expect.
E)The nasalance score can be in the normal range with mild nasal emission.

Question 13

High vowels have more nasal resonance than low vowels due to which of the following?

C)A slightly higher average nasalance score
D)A slightly lower average nasalance score
E)Nasalance scores higher than 20%
