Practice Question
A nurse is caring for a client admitted to the trauma medical unit.
Answer Choices:
Rationale:
👍The client is showing clinical signs consistent with fat embolism syndrome (FES), a serious complication of long bone fractures such as a femur fracture.
👍The findings of restlessness, irritability, and disorientation reflect neurologic changes caused by hypoxemia, as fat globules obstruct cerebral circulation.
👍The drop in oxygen saturation to 92% with new bilateral crackles indicates pulmonary involvement, where emboli and fluid impair alveolar gas exchange.
👍The fever of 38.3 °C (100.9 °F) represents a systemic inflammatory response triggered by fat emboli circulating in the bloodstream.
👍The presence of petechiae on the chest is the classic hallmark sign of FES, caused by dermal capillary occlusion.
👍Together, these symptoms form the classic triad of fat embolism syndrome—hypoxemia, neurologic changes, and petechiae— confirming this as the potential complication of the client’s injury.
