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 Reason:

Osteoporosis is inappropriate. Chronic respiratory acidosis can lead to osteoporosis over time due to several factors, including chronic hypoxemia, which can affect bone metabolism and lead to bone loss.

Choice B Reason:

Polyuria is inappropriate. Polyuria, or increased urination, is not typically associated with chronic respiratory acidosis. In fact, respiratory acidosis tends to cause retention of bicarbonate ions, which can lead to compensatory metabolic alkalosis and decreased urine output.

Choice C Reason:

Anxiety and depression is inappropriate. Chronic respiratory acidosis can lead to symptoms such as lethargy, confusion, and decreased mental acuity due to the effects of elevated CO2 levels on the central nervous system. While anxiety and depression are not direct consequences of chronic respiratory acidosis, individuals with COPD may experience anxiety and depression as a result of their chronic respiratory condition.

Choice D Reason:

Delirium is correct. Delirium, characterized by an acute change in mental status, confusion, and altered consciousness, can occur in severe cases of chronic respiratory acidosis, especially during acute exacerbations. Elevated CO2 levels can affect brain function and lead to symptoms of delirium.

Choice A Reason:

Muscle strength is correct. Assessing muscle strength is essential to determine if there are any neurological deficits or weakness that could indicate a neurological condition or injury. Sudden falls can be indicative of various neurological issues, such as stroke or transient ischemic attack (TIA). Assessing muscle strength helps identify any motor impairments or weakness that could contribute to the fall.

Choice B Reason:

Facial symmetry is correct. Assessing facial symmetry is crucial to identify any signs of facial droop, which could indicate a neurological deficit such as a stroke or Bell's palsy. Facial asymmetry may suggest damage to the facial nerve or other neurological issues.

Choice C Reason:

Peripheral pulses is incorrect. While assessing peripheral pulses is important for evaluating circulation, it may not be the priority assessment in this scenario where the client has suddenly fallen and may be experiencing neurological symptoms. Neurological deficits, such as weakness or changes in facial symmetry, vision, or speech, are more indicative of acute neurological issues like stroke or transient ischemic attack (TIA), which require immediate attention and intervention. In emergency situations, prioritizing assessments related to potential life-threatening conditions such as neurological deficits takes precedence over assessing peripheral pulses.

Choice D Reason:

Vision changes is correct. Assessing for vision changes is important to identify any visual disturbances or deficits that could contribute to falls or indicate underlying neurological issues such as a stroke or transient ischemic attack (TIA). Visual disturbances may include blurriness, double vision, or loss of vision in one or both eyes.

Choice E Reason:

Aphasia is incorrect. Assessing for aphasia, which is the inability to understand or express speech, is essential to identify any language deficits that could indicate a neurological condition such as a stroke. Aphasia may present as difficulty speaking, understanding language, or both.
