Which of the following is the most common risk factor for emphysema?
Smoking tobacco
Between 20 to 30 years of age
Asthma
Pollution
The Correct Answer is A
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.

Correct Answer is A
Explanation
Choice A Reason:
Hypertension is correct. This is a modifiable risk factor for stroke. Hypertension, or high blood pressure, significantly increases the risk of stroke. Treating and controlling hypertension through lifestyle changes and medication can help reduce the risk of stroke.
Choice B Reason:
Client's age is incorrect. While age itself is not modifiable, age is a non-modifiable risk factor for stroke. Risk of stroke increases with age, particularly in individuals over 55 years old. However, other modifiable risk factors can be addressed to reduce overall risk.
Choice C Reason:
History of sickle cell disease is incorrect. Sickle cell disease is a genetic disorder characterized by abnormal hemoglobin in red blood cells. While sickle cell disease increases the risk of certain complications, such as stroke in children, it is not a modifiable risk factor in the traditional sense.
Choice D Reason:
Parent who has cardiovascular disease is incorrect. While having a parent with cardiovascular disease may indicate a genetic predisposition to certain risk factors, it is not a direct modifiable risk factor for stroke. However, individuals with a family history of cardiovascular disease may have increased awareness and motivation to address modifiable risk factors such as hypertension, smoking, and diabetes.
Correct Answer is ["A","C","D","E"]
Explanation
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.
