    a. Rhinorrhea
    b. Periorbital edema
    c. Pain over the maxillary sinuses
    d. Enlarged superficial cervical nodes

Answer 28

d. Enlarged superficial cervical nodes
The lymphatic drainage of the external ear flows to the parotid, mastoid, and superficial cervical nodes. The signs are severe swelling of the canal, inflammation, and tenderness. Rhinorrhea, periorbital edema, and pain over the maxillary sinuses do not occur with otitis externa.

Question 29

When performing an otoscopic examination of a 5-year-old child with a history of chronic ear infections, the nurse sees that his right tympanic membrane is amber-yellow in color and that air bubbles are visible behind the tympanic membrane. The child reports occasional hearing loss and a popping sound with swallowing. The preliminary analysis based on this information is that the child:

a. Most likely has serous otitis media.
b. Has an acute purulent otitis media.
c. Has evidence of a resolving cholesteatoma.
d. Is experiencing the early stages of perforation.

Answer 29

a. Most likely has serous otitis media.

An amber-yellow color to the tympanic membrane suggests serum or pus in the middle ear. Air or fluid or bubbles behind the tympanic membrane are often visible. The patient may have feelings of fullness, transient hearing loss, and a popping sound with swallowing. These findings most likely suggest that the child has serous otitis media. The other responses are not correct.

Question 30

The nurse is performing an assessment on a 65-year-old man. He reports a crusty nodule behind the pinna. It intermittently bleeds and has not healed over the past 6 months. On physical assessment, the nurse finds an ulcerated crusted nodule with an indurated base. The preliminary analysis in this situation is that this:

a. Is most likely a benign sebaceous cyst.
b. Is most likely a keloid.
c. Could be a potential carcinoma, and the patient should be referred for a biopsy.
d. Is a tophus, which is common in the older adult and is a sign of gout.

Answer 30

c. Could be a potential carcinoma, and the patient should be referred for a biopsy.

An ulcerated crusted nodule with an indurated base that fails to heal is characteristic of a carcinoma. These lesions fail to heal and intermittently bleed. Individuals with such symptoms should be referred for a biopsy. The other responses are not correct.

Question 31

The nurse suspects that a patient has otitis media. Early signs of otitis media include which of these findings of the tympanic membrane?

a. Red and bulging
b. Hypomobility
c. Retraction with landmarks clearly visible
d. Flat, slightly pulled in at the center, and moves with insufflation

Answer 31

b. Hypomobility

An early sign of otitis media is hypomobility of the tympanic membrane. As pressure increases, the tympanic membrane begins to bulge.

Question 32

The nurse is performing a middle ear assessment on a 15-year-old patient who has had a history of chronic ear infections. When examining the right tympanic membrane, the nurse sees the presence of dense white patches. The tympanic membrane is otherwise unremarkable. It is pearly, with the light reflex at 5 oclock and landmarks visible. The nurse should:

a. Refer the patient for the possibility of a fungal infection.
b. Know that these are scars caused from frequent ear infections.
c. Consider that these findings may represent the presence of blood in the middle ear.
d. Be concerned about the ability to hear because of this abnormality on the tympanic membrane.

Answer 32

b. Know that these are scars caused from frequent ear infections.

Dense white patches on the tympanic membrane are sequelae of repeated ear infections. They do not necessarily affect hearing.

Question 33

The nurse is preparing to do an otoscopic examination on a 2-year-old child. Which one of these reflects
the correct procedure?
a. Pulling the pinna down
b. Pulling the pinna up and back
c. Slightly tilting the childs head toward the examiner
d. Instructing the child to touch his chin to his chest

Answer 33

a. Pulling the pinna down

For an otoscopic examination on an infant or on a child under 3 years of age, the pinna is pulled down. The other responses are not part of the correct procedure.

Question 34

The nurse is conducting a child safety class for new mothers. Which factor places young children at risk for ear infections?

a. Family history
b. Air conditioning
c. Excessive cerumen
d. Passive cigarette smoke

Answer 34

d. Passive cigarette smoke

Question 35

During an otoscopic examination, the nurse notices an area of black and white dots on the tympanic membrane and the ear canal wall. What does this finding suggest?

a. Malignancy
b. Viral infection
c. Blood in the middle ear
d. Yeast or fungal infection

Answer 35

d. Yeast or fungal infection

A colony of black or white dots on the drum or canal wall suggests a yeast or fungal infection (otomycosis).

Question 36

A 17-year-old student is a swimmer on her high schools swim team. She has had three bouts of otitis externa this season and wants to know what to do to prevent it. The nurse instructs her to:

a. Use a cotton-tipped swab to dry the ear canals thoroughly after each swim.
b. Use rubbing alcohol or 2% acetic acid eardrops after every swim.
c. Irrigate the ears with warm water and a bulb syringe after each swim.
d. Rinse the ears with a warmed solution of mineral oil and hydrogen peroxide.

Answer 36

b. Use rubbing alcohol or 2% acetic acid eardrops after every swim.

Question 37

During an examination, the patient states he is hearing a buzzing sound and says that it is driving me crazy! The nurse recognizes that this symptom indicates:

a. V ertigo.
b. Pruritus.
c. Tinnitus.
d. Cholesteatoma.

Answer 37

c. Tinnitus.

Question 38

38. During an examination, the nurse notices that the patient stumbles a little while walking, and, when she sits down, she holds on to the sides of the chair. The patient states, It feels like the room is spinning! The nurse notices that the patient is experiencing:
    a. Objective vertigo.
    b. Subjective vertigo.
    c. Tinnitus.
    d. Dizziness.

Answer 38

a. Objective vertigo.
With objective vertigo, the patient feels like the room spins; with subjective vertigo, the person feels like he or she is spinning. Tinnitus is a sound that comes from within a person; it can be a ringing, crackling, or buzzing sound. It accompanies some hearing or ear disorders. Dizziness is not the same as true vertigo; the person who is dizzy may feel unsteady and lightheaded.

Question 39

A patient has been admitted after an accident at work. During the assessment, the patient is having trouble hearing and states, I dont know what the matter is. All of a sudden, I cant hear you out of my left ear! What should the nurse do next?

a. Make note of this finding for the report to the next shift.
b. Prepare to remove cerumen from the patients ear.
c. Notify the patients health care provider.
