Question 3

The medial edge of the vocal fold (the “vibratory edge”) where one fold contracts the other should, in normal healthy tissue be characterized by…

Answer 3

smooth and straight

Question 4

What flexible endoscopic technology can produce images that rival those from rigid endoscopes?

Answer 4

video endoscopes

Question 5

Which of the following is NOT a material/equipment needed when performing laryngoscopy with stroboscopy?

none- you WILL need gloves, gauze, and a light source

Question 6

What information controls the flash rate of stroboscopic light for laryngoscopy with stroboscopy?

Answer 6

the patient’s fundamental frequency

Question 7

Which of the following is an advantage of a flexible endoscope over a rigid endoscope?

Answer 7

less likely to elicit a gag reflex

Question 8

A recommended patient position for rigid laryngoscopy includes…

Answer 8

sitting forward with chin out as when sniffing

to prevent fogging

Answer 13

muscle tension dysphonia

Question 14

Healthy vocal folds are characterized by what color?
