Question

Quizplus · Accepted Answer

Clubbing of the fingers is a response to chronic hypoxemia, which refers to low oxygen levels in the blood over a prolonged period of time. It is frequently seen in patients with conditions such as lung cancer, cystic fibrosis, and emphysema, which can cause chronic respiratory insufficiency and hypoxemia. CO₂ retention and acidosis may also be present in these conditions, but they are not the direct cause of clubbing. Acute hyperventilation in response to metabolic acidosis and chronic dry hacking cough are also not the causes of clubbing.
