She takes a deep breath and then coughs multiple times, sometimes so much that she vomits. When she tries to catch her breath after a coughing spell, she has difficulty. She reports the cough has persisted for 3 weeks and usually comes in fits. Vital signs are stable. Physical examination is benign. You send cultures and a PCR of her secretions, both of which come back positive for the organism you had suspected.

A 42-year-old female is noted to have a solitary pulmonary nodule in the right upper lobe on a routine plain chest film. This was not evident on a chest film taken one year earlier. The patient has a history of invasive ductal carcinoma of the right breast; she underwent a mastectomy 6 years ago. At that time, no lymph nodes were involved. She has remained disease free for the past 6 years until the plain chest film confirmed the pulmonary nodule.  She has no known risk factors for pulmonary tuberculosis.  The patient smokes 5 cigarettes/day. She denies hemoptysis or other pulmonic or constitutional symptoms and denies recent domestic or foreign travel. On physical exam, her temperature is 98.2°F. She has no lymphadenopathy or abnormal palpable breast masses on the left side. Her CBC is normal. A Chest CT scan revealed only a nodular opacity in the right upper lobe measuring 2 cm x 1.5 cm.  Which of the following interventions is the most appropriate next step in the diagnostic evaluation of this patient?

A 62-year-old male presents to the Emergency Department complaining of cough and chest pain. He states that the chest pain has been present for 2 weeks and worsens when he coughs. The patient has not been to a doctor in “years.” Initial CXR is obtained that is consistent with left-sided pneumonia. The patient is admitted for antibiotic treatment of pneumonia. On day 4 of his hospital course, the patient’s respiratory status worsens. Vital signs: 100°F, HR 118/min, RR 30/min, and oxygen saturation is 76% (room air). On physical exam, the patient appears drowsy and dyspneic. He cannot speak in full sentences. Lung exam reveals bilateral rales, and intercostal retractions are noted. The patient is placed on mechanical ventilation with improvement of his oxygen saturation to 84%. A repeat CXR is obtained (see image) and reveals diffuse, bilateral coalescent opacities.                                                                                             Which of the following statements about this condition is TRUE?
