Question 4 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 5 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.
