A client is taking aspirin for stroke prevention and reports the development of hearing disturbances. The appropriate nursing intervention is to ask the provider to decrease the dose in order to prevent which condition?

Choice A rationale Otitis externa is an inflammation or infection of the external auditory canal, often referred to as swimmer ear. It is typically caused by bacterial or fungal overgrowth in the outer ear canal due to moisture or trauma. Aspirin use does not have a known physiological mechanism that would cause infection of the external ear structure. The symptoms mentioned, like hearing disturbances, originate in the inner ear or nerve pathways rather than the external canal. Choice B rationale Vertigo is a sensation of spinning or dizziness often associated with inner ear imbalances or vestibular nerve issues. While aspirin can sometimes cause dizziness as a side effect, the specific report of hearing disturbances is more indicative of damage to the cochlear system rather than just a balance issue. Vertigo alone does not capture the full scope of potential sensory damage to the cranial nerve VIII that high doses of acetylsalicylic acid can cause over time. Choice C rationale Nystagmus involves involuntary, rapid, and repetitive eye movements that can be horizontal, vertical, or rotary. It is often a sign of vestibular dysfunction or central nervous system pathology. Although aspirin toxicity can affect the neurological system, nystagmus is not the primary or most common indicator of salicylate-induced sensory damage. Hearing loss and tinnitus are the classic early warning signs of aspirin reaching toxic levels in the blood, which requires immediate dose adjustment. Choice D rationale Ototoxicity refers to the toxic effect that certain medications, including high-dose aspirin, have on the inner ear or the vestibulocochlear nerve. Salicylates can disrupt the electrochemical balance in the cochlea, leading to tinnitus and hearing impairment. Monitoring for these symptoms is crucial because the damage can sometimes become irreversible if the dose is not reduced. By decreasing the aspirin dosage, the nurse helps protect the delicate sensory hair cells from further chemical-induced injury.
