In suspected asthma, chest X-ray is typically used to evaluate for which condition?

• A. Pneumonia
• B. Lung cancer
• C. Tuberculosis
• D. Pulmonary embolism

Answer: (D)

In suspected asthma, a chest X-ray is not used to diagnose asthma itself. Its main role is to screen for other conditions that can mimic or worsen wheezing and dyspnea, guiding further evaluation. Pulmonary embolism is an important alternative cause of acute chest symptoms that clinicians consider early in the workup; a chest X-ray is routinely obtained to rule out or identify other problems (like infection or heart/lung abnormalities) and to direct additional testing such as CT angiography if suspicion remains. Although chest X-ray cannot diagnose PE, it helps narrow the differential and ensure nothing acute is missed.
