What clinical signs and symptoms help differentiate a pulmonary embolism from pneumonia or COPD exacerbation? What might you expect to hear during auscultation and why?

Patient: Name: Margaret “Maggie” S. Age: 68 Sex: Female Occupation: Retired postal worker History of Present Illness:Maggie presents to her primary care provider with increasing shortness of breath on exertion, productive cough, fatigue, and an unintentional 10-lb weight loss over the last 3 months.

CT scan: Confirms a right upper lobe mass with partial lobar collapse. a. What features of Maggie’s history suggest that smoking has contributed significantly to her current condition?b. What pulmonary conditions are most commonly associated with long-term cigarette smoking? Given the patient’s history and imaging findings, what is the most likely underlying condition causing the right upper lobe mass? What breath sounds would you expect to hear over the affected region with atelectasis and infection?
