Answer to Question 1

ANS: B
Sensorineural hearing loss, also known as perceptive or nerve deafness, involves damage to the inner ear structures or the auditory nerve. It results in distortion of sounds and problems in discrimination. Conductive hearing loss involves mainly interference with loudness of sound. Mixed conductive-sensorineural hearing loss manifests as a combination of both sensorineural and conductive loss. The central auditory imperceptive category includes all hearing losses that do not demonstrate defects in the conduction or sensory structures.

Answer to Question 2

ANS: C
Children with Down syndrome are at risk for atlantoaxial instability. Before participating in sports that put stress on the head and neck, a radiologic examination should be done. Although hyperflexibility, cutis marmorata, and Brushfield's spots are characteristics of Down syndrome, they do not affect the child's ability to participate in sports.
