  4. Bradypnea, bradycardia, decreased temperature, shortness of breath
Explanation
Answer - A - Signs and symptoms of fat emboli include tachypnea, tachycardia, elevated temperature, thrombocytopenia, and mild neurological symptoms like confusion. Petechial rash on the upper anterior portion of the body occurs late and disappears within hours. Fractures involving the long bones release a great amount of fat into the marrow vessels that obstruct the pulmonary and systemic vasculature.
