Frontal lobe
Occipital lobe
Temporal lobe

Explanation
Choice A rationale: Tachycardia and petechiae over the chest wall and buccal membranes are signs of fat embolism syndrome, another complication of fractures that occurs when fat globules enter the bloodstream and obstruct pulmonary vessels.
Choice B rationale: Positive Homan's sign with calf tenderness and warmth are signs of deep vein thrombosis, a condition that can occur after prolonged immobilization or surgery.
Choice C rationale: Acute cough, cyanosis, and decreased blood pressure are signs of pulmonary embolism, a life-threatening condition that occurs when a blood clot travels to the lungs and blocks blood flow.
Choice D rationale: These are signs of compartment syndrome, which is a serious complication of fractures that occurs when increased pressure within a closed space compromises blood flow and tissue perfusion. Compartment syndrome can lead to ischemia, necrosis, and nerve damage if not treated promptly.
