Final answer:
When a lung nodule is found on a chest X-ray, it is important for patients to follow up with a repeat CXR to monitor the nodule over time.
Step-by-step explanation:
When a lung nodule is found on a chest X-ray, it is important for patients to follow up with a repeat CXR. The reason for this is that lung nodules can sometimes be an early sign of lung cancer or other serious conditions. By getting a repeat CXR, doctors can monitor the size and appearance of the nodule over time to determine if further testing or treatment is necessary. This can help catch any potential problems early and improve outcomes.
