A nurse is teaching a group of clients about lifestyle modifications that could decrease risk factors for developing hearing loss. Which of the following risk factors should the nurse include in the teaching?

Choice A reason: Smoking is a modifiable risk factor for hearing loss. Tobacco use can impair blood flow to the cochlea and increase oxidative stress, contributing to sensorineural hearing damage. Choice B reason: While potassium is important for general health, there is no direct evidence that high potassium intake prevents hearing loss. This is not a recognized preventive strategy. Choice C reason: Limiting alcohol may benefit overall health, but moderate alcohol consumption is not directly linked to hearing loss prevention. Excessive alcohol, however, may contribute to auditory nerve damage. Choice D reason: Adequate hydration is important for systemic health but does not specifically reduce the risk of hearing loss.
