Question 3 of 5
Following a stab wound in the chest wall, the lung will and the chest wall will?
Correct Answer: D
Rationale: A stab wound causing pneumothorax collapses the lung (intrapleural pressure equals atmospheric, 0 mmHg) and expands the chest wall (outward recoil). Lung collapse (D) loses negative pressure (-5 cm H2O at FRC). Chest expansion (not A or C) follows elastic recoil. FRC fixation (B) doesn't occur air entry disrupts balance. D's dynamics unlike A's dual expansion match pneumothorax physiology (Q58).
Question 4 of 5
Which of the following will decrease diffusion?
Correct Answer: D
Rationale: All factors (D) reduce diffusion . Fick's law: rate = D × A × ΔP / d. Decreased area (A, e.g., emphysema, Q59) cuts A (70 m^2 to 35 m^2). Fluid (B, pulmonary edema, Q55) thickens d (0.2 μm to 1 μm). Pressure coefficient' (C) likely means ΔP lowering it (e.g., 60 to 30 mmHg) slows flow. Each halves diffusion (e.g., O2 from 250 mL/min); combined, they compound loss. D's inclusivity unlike A's single factor matches physiology's multifactorial model.
Question 5 of 5
A patient with restrictive lung disease will have a relatively normal?
Correct Answer: D
Rationale: Restrictive disease (e.g., fibrosis) keeps FEV1/FVC normal or high. Both FEV1 and FVC drop proportionally (e.g., 2.5 L and 3 L vs. 4 L and 5 L), ratio ≥ 80% (Q1). FEV1 (A) and FVC (B) decrease due to stiff lungs (compliance < 0.2 L/cm H2O). V/Q (C) may skew (fibrosis raises it). D's stability unlike A's absolute fall reflects restriction's even reduction, per spirometry (Q54).
