The nurse monitors for early signs of fat embolism in a client with a long bone fracture. Which criterion indicates early nervous system involvement?

The nurse monitors for early signs of fat embolism in a client with a long bone fracture. Which criterion indicates early nervous system involvement?

• A. The client’s mental status
• B. The client’s respiratory rate
• C. The client’s blood pressure
• D. The client’s abdominal pain

Answer: (A)

Early nervous system involvement in fat embolism syndrome is shown by a change in the patient’s mental status. Fat droplets can travel to the brain and disrupt cerebral perfusion, leading to restlessness, confusion, agitation, or a decreased level of consciousness. Because this CNS involvement often appears before other systems show overt signs, monitoring mental status is the best clue to early neurologic impact after a long bone fracture. Changes in respiratory rate reflect pulmonary involvement, not the brain. Blood pressure changes and abdominal pain are not specific early indicators of CNS involvement in fat embolism syndrome.
