NR 507: Advanced Pathophysiology Midterm Exam well solved

NR 507: Advanced Pathophysiology Midterm Exam well solved Asthma -Correct Answer-Chronic disease due to bronchoconstriction and an excessive inflammatory response in the bronchioles What are 5 s/s of asthma -Correct Answer-coughing wheezing shortness of breath rapid breathing chest tightness Pathophysiology of asthma (5) -Correct Answer--airway inflammation, bronchial hyper-reactivity and smooth muscle spasm -excess mucus production and accumulation -hypertrophy of bronchial smooth muscle -airflow obstruction -decreased alveolar ventilation Bronchioles -Correct Answer-smaller passageways that originate from the bronchi that become the alveoli 3 layers of the bronchioles -Correct Answer-innermost layer middle layer - lamina propria outermost layer lamina propria -Correct Answer-the middle layer of the bronchioles structure of the lamina propria -Correct Answer-embedded with connective tissue cells and immune cells purpose of the lamina propria -Correct Answer-white blood cells are present to help protect the airways How does the lamina propria effect the lungs in regards to asthma -Correct Answer-the WBCs protective feature goes into overdrive causing an inflammatory response that damages host tissue What does the innermost layer of the bronchioles contain -Correct Answer-columnar epithelial ells and mucus producing goblet cells What does the outermost layer of the bronchioles contain -Correct Answer-smooth muscle cells what does the outermost layer of the bronchioles do -Correct Answer-control the airways ability to constrict and dilate alveolar hyperinflation -Correct Answer-When air is unable to move out of the alveolar like it should due to bronchial walls collapsing around possible mucus plug thus trapping air inside how does hyperinflation occur? -Correct Answer-the ongoing inflammatory process of asthma produces mucus and pus plug that the bronchial walls collapse around
