Analysis of aerial blood gases discloses respiratory alkalosis and theperipheral eosinophil count is increased. What is the appropriate diagnosis?
Correct Answer: Asthma
Description: Asthma is a chronic lung disease caused by increased responsiveness ( inflammatory reaction) of the airways to a variety of stimuli either extrinsic (e.g., pollen) or intrinsic (e.g., exercise). Extrinsic asthma is typically a childhood disease, whereas intrinsic asthma usually begins in adults. Patients typically have paroxysms of wheezing, dyspnea and cough.
