    Included Quiz Questions

    1. Airway remodelling
    2. Airway hyperresponsiveness
    3. Airway inflammation
    4. Airway epithelial shedding
    5. Airway smooth muscle atrophy
    1. External intercostal muscles
    2. Internal intercostal muscles
    3. Scalene muscles
    4. Sternocleidomastoid muscles
    5. Muscles of anterior abdominal wall
    1. Decreased pulmonary artery pressure
    2. Increased central hypercapnic ventilatory responsiveness
    3. Increased sympathetic activity
    4. Prolonged lung-to-brain circulation time
    5. Hypoxemia
    1. Microcytic hypochromic anemia seen in this condition responds poorly to oral iron therapy.
    2. Haemophilus influenzae is most common organism causing spontaneous bacterial peritonitis.
    3. Intrinsic renal failure is the most common type of acute renal failure.
    4. As there is increased risk of thromboembolism, prophylactic anticoagulation is indicated in all patients.
    5. Hypocalcemia is most commonly due to urinary loss of calcium.
    1. Phases III and IV are mediated by baroreceptor reflexes that require intact efferent sympathetic responses.
    2. During phase I, blood pressure rises due to increased intrathoracic pressure.
    3. During early phase II, normally there is fall in blood pressure and rise in heart rate.
    4. During late phase II, normally there is increase in both blood pressure and heart rate.
    5. Valsalva ratio is defined as the maximum phase II tachycardia divided by the minimum phase IV bradycardia.
    1. Decreased FEV1 and FVC with normal FEV1/FVC
    2. Decreased FEV1 and normal FVC
    3. Decreased FEV1 and FVC with decreased FEV1/FVC
    4. Increased FEV1 and FVC
    5. Normal FEV1 and FVC
    1. By simple diffusion
    2. By facilitated diffusion
    3. By primary active transport
    4. By co-transport
    5. By counter-transport
    1. Low ventilation, normal perfusion and low V/Q ratio
    2. Lower ventilation and perfusion, but higher V/Q ratio
    3. Normal ventilation, low or nonexistent perfusion and infinite V/Q ratio
    4. Higher ventilation and perfusion with lower V/Q ratio
    5. Medium ventilation and perfusion, V/Q that equals 0.8
    1. Trypsin

    1. Selective β-blockers
    2. Nonselective β-blockers
    3. β-agonists
    4. α- agonists
    5. α- antagonists
