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.)
Decreased visual acuity
Motor vehicle crashes
Polypharmacy
Weakness
Chronic hypertension
Previous military experience
Correct Answer : A,C,D,E
Choice A Reason:
Decreased visual acuity is correct. Yes, decreased visual acuity, including issues such as poor depth perception, reduced peripheral vision, and difficulty with contrast sensitivity, can contribute to falls and head injuries in older adults.
Choice B Reason:
Motor vehicle crashes is incorrect. While motor vehicle crashes can cause head injuries in individuals of all ages, they are less common among older adults compared to younger age groups.
Choice C Reason:
Polypharmacy is correct. Yes, polypharmacy, which refers to the use of multiple medications concurrently, is a common risk factor for falls and head injuries in older adults. Certain medications, especially those with sedative or psychotropic effects, can increase the risk of falls and accidents.
Choice D Reason:
Weakness is correct. Yes, weakness, frailty, and decreased muscle strength are common age-related changes that can increase the risk of falls and subsequent head injuries in older adults.
Choice E Reason:
Chronic hypertension, particularly when poorly controlled, can contribute to an increased risk of falls in older adults through various mechanisms:Hypertension medications or the condition itself can lead to orthostatic hypotension. This can cause dizziness or lightheadedness, increasing the risk of falls. Chronic hypertension is a major risk factor for cerebrovascular disease, including strokes. These events can lead to neurological deficits such as weakness, numbness, or impaired balance, predisposing individuals to falls.
Choice F Reason:
Previous military experience is incorrect. While previous military experience may contribute to certain health conditions or injuries in older adults, it is not a common reason for head injuries specifically related to falls or accidents in this population.

Correct Answer is D
Explanation
"The nerves just go to sleep when I lie down because no message gets from my brain to the spinal cord." is incorrect because it does not accurately describe the mechanism of peripheral neuropathy. Peripheral neuropathy in diabetes is not simply the nerves "going to sleep" due to lack of communication between the brain and spinal cord.
Choice B Reason:
"The nerve damage may occur for unknown reasons in any individual" is incorrect because while the exact cause of peripheral neuropathy may not always be known, in the context of diabetes mellitus, the link between elevated blood sugar levels and nerve damage is well-established.
Choice C Reason:
"The older I get, there is less blood flowing to my feet. “is incorrect because while decreased blood flow (ischemia) can contribute to peripheral neuropathy in some cases, the primary mechanism in diabetic neuropathy is nerve damage due to hyperglycemia rather than reduced blood flow.
Choice D Reason:
"The elevated blood sugar from my diabetes can cause underlying nerve damage." Peripheral neuropathy is a common complication of diabetes mellitus, particularly when the condition is uncontrolled. Elevated blood sugar levels over time can lead to damage to the nerves, especially those in the feet and legs. This damage can result in symptoms such as numbness, tingling, burning sensations, or pain in the affected areas.
Correct Answer is A
Explanation
Choice A Reason:
Smoking tobacco is the primary and most significant risk factor for emphysema. Tobacco smoke contains harmful chemicals and toxins that directly damage the lungs. Chronic exposure to cigarette smoke leads to inflammation and destruction of lung tissue, particularly the alveoli, contributing to the development of emphysema.
Choice B Reason:
Between 20 to 30 years of age. While smoking at any age is harmful to lung health, the risk of developing emphysema increases with prolonged exposure to tobacco smoke over many years. Emphysema is typically a disease of middle to older age, with symptoms often appearing after years of smoking.
Choice C Reason:
Asthma is a chronic inflammatory condition of the airways characterized by reversible airflow obstruction and airway hyperresponsiveness. While asthma and emphysema are both respiratory diseases, they have distinct pathophysiological mechanisms and risk factors. Asthma is not a direct cause of emphysema, although some individuals with poorly controlled asthma may develop chronic obstructive pulmonary disease (COPD), which includes emphysema as one of its components.
Choice D Reason:
Pollution is not correct. Environmental pollution, including air pollution from industrial emissions, vehicle exhaust, and particulate matter, can contribute to respiratory problems and exacerbate pre-existing lung conditions. While exposure to pollution can worsen respiratory symptoms and lung function, it is not the primary cause of emphysema. However, long-term exposure to certain pollutants may increase the risk of developing respiratory diseases, including COPD, which encompasses emphysema.
