George, a 15-year-old man, is brought to the ESL with multiple rib fractures following a motor vehicle accident. How could this injury affect his respiratory system?
It will enhance the diffusion of gases
It will increase the diaphragmatic workload
It will compromise the efficiency of ventilation
It will improve pulmonary blood supply
The Correct Answer is C
A. Multiple rib fractures are unlikely to enhance gas diffusion; instead, they can impair ventilation by reducing the ability of the chest wall to expand.
B. Multiple rib fractures can indeed increase the workload of the diaphragm as it tries to compensate for the decreased ability of the chest wall to expand during breathing.
C. Multiple rib fractures can restrict chest wall movement, leading to compromised ventilation efficiency.
D. Multiple rib fractures wouldn't directly improve pulmonary blood supply; they can lead to pain and impaired lung function.
