Breath sounds in the affected area of chest trauma with rib fractures are typically?

• A. Diminished over affected area
• B. Wheezes throughout
• C. Crackles across both lungs
• D. Normal bilaterally

Answer: (A)

Pain from rib fractures causes the patient to take shallow breaths on the injured side, so less air reaches that lung region. That reduced ventilation leads to diminished breath sounds over the affected area. The other patterns don’t fit this scenario: wheezes would suggest airway obstruction or reactive bronchospasm, crackles across both lungs point to fluid or alveolar involvement not specific to one fractured rib, and normal breath sounds bilaterally would be unlikely when the chest is injured. Diminished breath sounds over the affected side reflect the typical immediate effect of chest trauma with rib fractures.
