Which examination is indicated for the client with rust-colored sputum due to recent travel, Darius Lance?

A chest X-ray is indicated for a client presenting with rust-colored sputum, particularly in the context of recent travel. This symptom can suggest a possible respiratory infection, such as pneumonia, which could be caused by pathogens like Streptococcus pneumoniae or even atypical organisms depending on exposure to endemic areas. A chest X-ray provides a visual assessment of the lungs and can help identify the presence of infiltrates, consolidations, or other abnormalities that could clarify the underlying cause of the sputum color change.

In the case of Darius Lance, the recent travel history combined with rust-colored sputum raises suspicion for potentially infectious processes, making the chest X-ray a critical first step in evaluation. Other imaging methods or tests would not provide the same level of specific information regarding respiratory conditions.
