What kind of otitis media is a pathogen-free fluid behind the tympanic membrane, resulting from irritation associated with respiratory allergies and enlarged adenoids?
- A. Purulent otitis media
- B. Infectious otitis media
- C. Serous otitis media
- D. Sterile otitis media
Correct Answer: C
Rationale: Serous otitis media, a collection of pathogen-free fluid behind the tympanic membrane, results from irritation associated with respiratory allergies and enlarged adenoids. The other options are distractors for this question. Purulent otitis media usually results from the spread of microorganisms from the eustachian tube to the middle ear during upper respiratory infections.

The nurse is caring for a client in the triage section of a walk-in clinic. Which triad of common symptoms suggests a diagnosis of M?©ni?¨re disease?
- A. Blurred vision, vertigo, nausea
- B. Syncope, vertigo, ear pain
- C. Disorientation, vertigo, nausea
- D. Hearing loss, vertigo, tinnitus

Rationale: Hearing loss, vertigo, and tinnitus are common symptoms of many disease processes but, when placed together, indicate M?©ni?¨re disease. The other options do not include the accurate triad of symptoms.
The nurse is caring for a client experiencing hearing loss. The nurse uses the otoscope to assess the ear canal and tympanic membrane and notes a significant accumulation of cerumen. Which documentation of hearing loss type would be accurate?
- A. Conductive
- B. Mixed
- C. Central
- D. Sensorineural
Correct Answer: A
Rationale: Conductive hearing loss occurs from an obstruction in the outer or middle ear such as from cerumen. Mixed hearing loss is a combination of conductive and sensorineural problems. Central hearing loss involves injury or damage to the nerves or the nuclei of the central nervous system. Sensorineural involves damage to the inner ear.
The nurse is caring for a client with recurrent ear infections. The nurse assesses the client for further infectious processes traveling deeper into the tissue and becoming more lethal. Which infection, originated in the ear, is of most concern?
- A. Mastoiditis
- B. Meningitis
- C. Sinusitis
- D. Labyrinthitis
Correct Answer: B
Rationale: The infection stemming from the ear may extend to the meninges, causing meningitis, or a brain abscess could occur. This could be life threatening. The other options are also potential complications of an ear infection but not as much of a concern as meningitis.
A nursing student is presenting a report on M?©ni?¨re disease to other members of the class. What symptom would the student list?
- A. Pinkish-orange eardrum
- B. Nystagmus of the eyes
- C. Enlarged lymph nodes behind the ear
- D. Swelling and redness in the auditory canal
Correct Answer: B
Rationale: Nystagmus of the eyes may occur in a client with M?©ni?¨re disease caused by an imbalance in vestibular control of eye movements. Pinkish-orange eardrums, enlarged lymph nodes, or swelling and redness in the auditory canal are not observed in a client with M?©ni?¨re disease.
A client comes to the walk-in clinic reporting feeling a 'bug in my ear.' What action should be taken when there is an insect in the ear?
- A. Instillation of mineral oil
- B. Instillation of carbamide peroxide
- C. Instillation of hot water
- D. Use of a small forceps
Correct Answer: A
Rationale: Mineral oil is instilled into the ear to smother an insect. Carbamide peroxide is used to soften dried cerumen, and small forceps are used to remove solid objects. Hot liquids cause dizziness and should not be instilled in the ear.
