Question 14

changing of direction and speed of a ray of light

Answer 14

refraction

Question 14

drooping of the eyelids

Answer 14

Question 15

assessment technique used to detect hearing loss by comparing bone conduction and air conduction of sound using a tuning fork

Answer 15

Rinne test

Question 16

assessment technique used to evaluate a person’s ability to sustain balance

Answer 16

Romberg test

Question 17

Hearing loss that is the result of nerve impairment

Answer 17

sensorineural hearing loss

Question 18

measurement of intraocular pressure

Answer 18

tonometry

Question 19

An instrument that produces sound in the same range as human speech; used to screen for conductive or sensorineural hearing loss

Answer 19

tuning fork

Question 20

ability to see far images clearly

Answer 20

visual acuity

Question 21

test of peripheral vision and detection of gaps in the visual field

Answer 21

visual field examination

Question 22

Assessment technique used to measure hearing loss by striking a tuning fork and placing its stem in the midline of the client’s skull or center of the forehead; a person with normal hearing perceives the sound equally well in both ears

Answer 22

Weber test
