The clinic nurse is assessing a child who has been brought to the clinic with signs and symptoms that are suggestive of otitis externa. What assessment finding is characteristic of otitis externa?

Correct Answer: C

Rationale: The correct answer is C: Pain on manipulation of the auricle is characteristic of otitis externa. This is because otitis externa is an infection or inflammation of the outer ear canal, causing pain and tenderness when the ear is touched or manipulated. A: Tophi on the pinna and ear lobe is characteristic of gout, not otitis externa. B: Dark yellow cerumen in the external auditory canal is common and not specific to otitis externa. D: Air bubbles visible in the middle ear are associated with otitis media, not otitis externa. In summary, pain on manipulation of the auricle is a key assessment finding in otitis externa, distinguishing it from other ear conditions.

Correct Answer: A

Rationale: The correct answer is A. Postoperative day 6 following tympanoplasty and mastoidectomy is still within the early phase of recovery, where occasional sharp, shooting pains in the affected ear can be expected due to the healing process. Here's a step-by-step rationale: 1. Timing: It is only day 6 post-surgery, so it is normal to experience some pain as part of the healing process. 2. Nature of pain: Sharp, shooting pains are common post-surgery due to tissue healing and nerve regeneration. 3. Lack of other symptoms: The patient did not report any other concerning symptoms like fever or discharge, which would be more indicative of an infection. 4. Unlikely complications: Spontaneous rupture of the tympanic membrane or unsuccessful surgery would typically present with more severe and consistent symptoms. Summary: - B: Unlikely as there are no other signs of infection. - C: Unlikely as the pain is described as occasional and sharp. - D:

Correct Answer: C

Rationale: The correct term for the involuntary, rhythmic eye movements seen in the patient with multiple sclerosis is nystagmus. Nystagmus is a condition characterized by repetitive, uncontrolled eye movements that can be horizontal, vertical, or rotary. In multiple sclerosis, nystagmus can occur due to damage to the nerves that control eye movement. Vertigo (choice A) is a sensation of spinning or dizziness, not related to eye movements. Tinnitus (choice B) is a perception of noise or ringing in the ears. Astigmatism (choice D) is a refractive error of the eye, not related to involuntary eye movements.

Correct Answer: D

Rationale: The correct answer is D because being aware of patients' medication regimens allows nurses to identify and monitor ototoxic medications that can cause hearing loss. By collaborating with other professionals, nurses can adjust medications or recommend alternative treatments to prevent or minimize ototoxicity. This proactive approach directly targets the root cause of potential hearing loss. A: Understanding types of hearing loss is important but does not directly prevent ototoxicity. B: Educating about age-related changes in hearing does not address ototoxicity prevention. C: Educating about noise exposure risks is important for overall hearing health but does not specifically prevent ototoxicity.

Correct Answer: A

Rationale: The correct answer is A: Preparation of nutritious meals and avoidance of contraindicated foods. After mastoid surgery, proper nutrition is crucial for healing and recovery. Nutritious meals support the immune system and aid in tissue repair. Avoiding contraindicated foods, such as those that may cause inflammation or interfere with medications, is essential for the patient's well-being. Choices B, C, and D are not the primary focus of home care after mastoid surgery. While rest, adaptation to hearing loss, and assistance with ambulation are important, they are secondary to ensuring proper nutrition for optimal recovery in this case.
