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 C
Explanation
Choice A Reason:
Decreased mucus production contributes to airway constriction: This statement is incorrect. Bronchospasm does not decrease mucus production; instead, it primarily affects the smooth muscles surrounding the bronchioles, leading to their constriction and narrowing of the airways. Increased mucus production, often accompanied by inflammation, can contribute to airway obstruction in conditions like asthma.
Choice B Reason:
Inflammation is reduced due to airway diameter: This statement is incorrect. Bronchospasm typically occurs in the setting of inflammation in conditions such as asthma. Constriction of the airways during bronchospasm exacerbates the inflammation and can further narrow the airways, leading to symptoms such as wheezing and dyspnea.
Choice C Reason:
Bronchospasm occurs when there is inflammation, edema, and excess mucus: This statement is partially correct. Bronchospasm often occurs in the presence of inflammation, edema, and excess mucus production, as seen in conditions like asthma. These factors contribute to airway hyperresponsiveness, leading to bronchospasm and airway narrowing.
Choice D Reason:
Airway obstruction occurs due to thinning mucus: This statement is incorrect. Airway obstruction in conditions like asthma is primarily due to bronchospasm, inflammation, and excessive mucus production, rather than thinning mucus. Thinning of mucus would not typically contribute to airway obstruction.
Correct Answer is ["C","D","E"]
Explanation
Choice A Reason:
Bladder spasms are not commonly reported as adverse effects of methylprednisolone. However, bladder dysfunction can occur in individuals with multiple sclerosis due to the disease process itself, but it is not specifically related to corticosteroid therapy.
Choice B Reason:
Hypotension is not a common adverse effect of methylprednisolone. In fact, corticosteroids can often lead to fluid retention and sodium retention, which can contribute to hypertension rather than hypotension.
Choice C Reason:
Delayed wound healing is correct. Corticosteroids can impair the body's ability to heal wounds by suppressing the inflammatory response and collagen synthesis. Therefore, clients receiving methylprednisolone may experience delayed wound healing, which can be problematic, especially in individuals with pre-existing wounds or undergoing surgical procedures.
Choice D Reason:
Hirsutism (excessive hair growth, especially in women) can occur with long-term corticosteroid use due to the effect of steroids on hair follicles. It is a possible adverse effect of methylprednisolone.
Choice E Reason:
Hyperglycemia is correct. Corticosteroids can increase blood glucose levels by promoting gluconeogenesis, reducing glucose uptake by tissues, and inducing insulin resistance. Clients receiving methylprednisolone may develop hyperglycemia, which can be particularly concerning for individuals with diabetes or those at risk of developing diabetes.
