Questions: Manifestations of Pulmonary Embolism include A Sudden onset of SOB, chest pain; ventilation-perfusion mismatch B Wheezing, anxiety, use of accessory muscles (C) Productive cough with rusty colored sputum, fever, malaise D Barrel chest, muscle wasting, prefers to sit upright or lean forward An inflammatory disorder triggered by an allergen that results in airway edema is

The answer to Question 16 is the first one (A): sudden onset of SOB, chest pain; ventilation-perfusion mismatch.

Explanation for each option: A. Sudden onset of SOB (shortness of breath), chest pain; ventilation-perfusion mismatch - This is correct because these are classic symptoms of a pulmonary embolism, which occurs when a blood clot blocks a blood vessel in the lungs, leading to a sudden onset of symptoms and a mismatch between ventilation and perfusion. B. Wheezing, anxiety, use of accessory muscles - These symptoms are more commonly associated with asthma or other obstructive airway diseases rather than a pulmonary embolism. C. Productive cough with rusty colored sputum, fever, malaise - These symptoms are indicative of pneumonia, not a pulmonary embolism. D. Barrel chest, muscle wasting, prefers to sit upright or lean forward - These are symptoms of chronic obstructive pulmonary disease (COPD), not a pulmonary embolism.

The answer to Question 17 is asthma.

Explanation: Asthma is an inflammatory disorder triggered by allergens or other irritants that result in airway edema, bronchoconstriction, and increased mucus production. This leads to symptoms such as wheezing, shortness of breath, chest tightness, and coughing.
