Chapter 16: Ears Jarvis: Physical Examination and Health Assessment, 8th Edition MULTIPLE CHOICE 1. The nurse is examining a patient’s ears and notices cerumen in the external canal. Which of
these statements about cerumen is correct? a. Wet, honey-colored cerumen is a sign of infection. b. The presence of cerumen is indicative of poor hygiene. c. The purpose of cerumen is to protect and lubricate the ear. d. Cerumen is necessary for transmitting sound through the auditory canal. ANS: C
The ear is lined with glands that secrete cerumen. Cerumen is genetically determined, with two distinct types. Wet, honey-brown occurs in Caucasians and African Americans, and a dry, flaky white is found in East Asians and American Indians. Cerumen is supposed to be present-to lubricate, waterproof, and clean the external auditory canal. It also is antibacterial, and traps foreign bodies. Wet, honey-colored cerumen is not a sign of infection. Cerumen is not a sign of poor hygiene. It is supposed to be present-to lubricate, waterproof, and clean the external auditory canal. It also is antibacterial, and traps foreign bodies. It is not necessary for transmitting sound through the auditory canal and too much cerumen can impair hearing.

When examining the ear with an otoscope, how should the tympanic membrane look? a. Light pink with a slight bulge b. Pearly gray and slightly concave c. Whitish with black flecks or dots d. Pulled in at the base of the cone of light ANS: B
The tympanic membrane is a translucent membrane with a pearly gray color and a prominent cone of light in the anteroinferior quadrant, which is the reflection of the otoscope light. The tympanic membrane is oval and slightly concave, pulled in at its center by the malleus, which is one of the middle ear ossicles. A light pink color and a slight bulge of the tympanic membrane indicate otitis media. It should not look white and if there are tiny black flecks or dots, that is indicative of a fungal infection, or otomycosis. The tympanic membrane does not appear pulled in at the base of the cone of light, but should instead appear flat and slightly pulled in at the center. A normal tympanic membrane should appear a pearly gray color and have a prominent cone of light in the anteroinferior quadrant, which is the reflection of the otoscope light. The tympanic membrane is oval and slightly concave, pulled in at its center by the malleus, which is one of the middle ear ossicles.

the best response by the nurse? a. It helps maintain balance.
