What is the causative organism that results in a fungal infection endemic to forest areas of North America high in decaying wood and most commonly located in central Southeast U.S.?

A patient with pancreatitis and pulmonary edema is placed on a mechanical ventilator. The initial ABG results on 100% oxygen are: pH 7.36, PaCO2 42 mmHg, PaO2 173 mmHg, HCO3 23 mEq/L with a calculated A-a gradient of 438 mmHg. Based on the A-a gradient, what pathophysiology is most likely?

Abscess formation follows a predictable pathological progression. Of the pathologic changes associated with lung abscess development, which is the LAST to occur?

You are called to attend to an ER patient complaining of shortness of breath and severe dyspnea on exertion. Patient history is significant for a 30 year-pack smoking history, dry non-productive cough and occasional pedal edema. CXR findings are not remarkable except for mild cardiomegaly. You want to rule out ILD vs. obstructive lung disease. Which of the following tests may help you to differentiate the diagnosis on this patient?I. sputum culture and sensitivityII. high resolution CTIII. pulmonary function testingIV. arterial blood gas analysisV. PET scan

During ARDS the destruction of Type I pneumocytes and presence of hyline membranes formed on the surface of the alveoli within 1-3 days is termed?

A patient is admitted to the ED which has been diagnosed with non-cardiogenic pulmonary edema. What pathophysiology is most likely responsible for the edema?

Ms. Queen is a 45 year old female patient admitted with fungal pneumonia. She weighs 65 kg, is otherwise healthy and is alert and oriented, but anxious. Her HR is 124 bpm. CXR reveals “diffuse, bilateral infiltrates without cavitation” unresolved after 4 days of treatment. Her ABGs reveal: pH 7.33, PaCO2 49 mmHg, PaO2 78 mmHg, HCO3 23 mEq/L on 0.35 AEM. Her RR = 32 bpm. She is diaphoretic with accessory muscle use and bilateral inspiratory crackles. Which of the following would you recommend?
