A nurse is caring for an older adult client in the emergency department who sustained a head injury due to a fall. Which of the following are common reasons for head injuries in older adults? (Select All that Apply)

Choice A rationale Decreased visual acuity, a common age-related change, significantly impairs an older adult's ability to perceive environmental hazards such as uneven surfaces or obstacles. This sensory deficit directly increases the risk of tripping and falling, leading to head injuries. Choice B rationale While older adults can be involved in motor vehicle crashes, it is not considered one of the *common reasons* for head injuries specifically *due to falls* in this demographic. Falls are a far more prevalent cause of head injuries in the elderly population compared to vehicular accidents. Choice C rationale Polypharmacy, the concurrent use of multiple medications, often leads to adverse drug reactions like orthostatic hypotension, dizziness, and altered gait. These side effects compromise balance and increase the likelihood of falls, a primary cause of head injuries in older adults. Choice D rationale Age-related sarcopenia and generalized muscle weakness diminish an older adult's ability to maintain balance and recover from a stumble. Weakness in lower extremities particularly reduces postural stability, making falls more probable and increasing susceptibility to head trauma. Choice E rationale Chronic hypertension itself does not directly cause falls or head injuries. However, poorly controlled hypertension or its treatment can sometimes lead to orthostatic hypotension, which can then contribute to falls. The direct link is less prominent than other factors. Choice F rationale Previous military experience has no direct scientific correlation with an increased risk of head injuries due to falls in older adults. This factor is irrelevant to the physiological and environmental causes of falls in the elderly population.
