During acute chest syndrome episodes, what pulmonary sign is often identified on examination?

• A. Wheezes
• B. Cough
• C. Tachypnea
• D. Clubbing

Answer: (C)

Acute chest syndrome is a serious complication often seen in individuals with sickle cell disease and is characterized by a range of pulmonary symptoms. During an acute chest syndrome episode, tachypnea, or an increased respiratory rate, is commonly observed on examination. This response is due to the body's efforts to compensate for decreased oxygenation and can be triggered by factors such as infections, pulmonary embolism, or fat embolism. Tachypnea indicates that the patient is experiencing respiratory distress, which can stem from pain, hypoxia, or decreased lung capacity, common in individuals experiencing lung-related crises. The presence of tachypnea serves as a crucial clinical sign that can prompt further assessment and management of the patient's respiratory status. While wheezes, cough, and clubbing are also pulmonary signs, they are not as consistently associated with acute chest syndrome as tachypnea. For instance, wheezing may suggest bronchospasm typically seen in asthma or other obstructive diseases but is not a hallmark of acute chest syndrome. Coughing may occur due to various respiratory conditions and clubbing is generally associated with chronic hypoxia or lung disease rather than acute events. Thus, tachypnea stands out as the most pertinent pulmonary sign during acute chest syndrome episodes.
