An admitted smoker for 18 years, the only respiratory symptom he reported was a persistent, mild, dry “smoker’s cough.” As a second thought, he mentioned that he had noticed a decrease in his usual “healthy” appetite and subsequently had lost a few pounds. Finally, he admitted to fatigue just getting through his daily routine. Further diagnostic studies indicated an 8 mm solitary pulmonary nodule identified as small cell lung cancer (SCLC). SCLC occurs almost exclusively in smokers; it has a rapid growth rate, and metastasizes early in the disease process. Mr. Johnson is scheduled for more diagnostic testing to determine the stage of the cancer and to detect metastatic lesions.   1. You had been asked to schedule the diagnostic workup for Mr. Johnson. What testing was necessary to specifically identify the nature of the cancer? 2. What might you understand about the doctor’s rationale for…
