A nurse is reviewing documentation for four older adult clients recently admitted to a skilled nursing facility. Which client should the nurse identify as having the highest immediate risk for fall-related injury?

A. A 78-year-old with bilateral cataracts and corrected hearing loss: Cataracts can impair vision and increase fall risk, but if hearing loss is corrected and no recent falls are noted, the immediate risk is lower compared to clients with multiple compounding factors. B. An 86-year-old recovering from pneumonia who ambulates with standby assistance: Recent illness and weakness increase fall risk, but having standby assistance during ambulation reduces the likelihood of injury. C. A 74-year-old with stage 1 Parkinson's disease and stable vital signs: Parkinson’s disease can impair gait and balance, but in stage 1, symptoms are generally mild and manageable. The risk of a severe fall-related injury is not as high as in a client with additional high-risk factors. D. An 81-year-old who uses a walker, takes warfarin, and has a history of falls: The combination of impaired mobility, a documented fall history, and anticoagulant therapy makes fall-related injury highly probable and more severe.
