He also complains of shortness of breath. He said he had been previously diagnosed with influenza but did not follow the doctors instructions. His vitals include: heart rate 70min, respiratory rate 22min, temperature 38.7C 101.7F, blood pressure 12060 mm Hg, and SO2 80. His hemogram and chest X-ray findings are as follows:Hemoglobin 14 mgdLHematocrit 45Leukocyte count 12,000mm3Neutrophils 82Lymphocytes 15Monocytes 3Platelet count 270,000mm3Chest X-ray alveolar infiltrates in the left base with air bronchogramsWhat is the most likely diagnosis?? A: Sarcoidosis, B: Pneumonia, C: Histoplasmosis, D: Lung cancer, E: Tuberculosis,  <response>: Based on the information provided in the question stem, the patient has symptoms of chest pain, productive cough, shortness of breath, fever, and hypoxemia. He has a history of recent influenza infection that was not properly treated. His lab results show elevated white blood cell count with neutrophilia, indicating infectioninflammation. The chest X-ray findings of alveolar infiltrates in the left lung base with air bronchograms are consistent with pneumonia. The most likely diagnosis given the clinical presentation and test results is bacterial pneumonia, which often occurs as a complication of inadequately treated influenza infection. The other answer choices of sarcoidosis, histoplasmosis, lung cancer, and tuberculosis are less likely based on the acute presentation and chest X-ray findings.B: Pneumonia
