Difficulty: MediumPhysiological Adaptation

A young adult client is being monitored on the orthopedic unit 24 hours after sustaining a closed comminuted fracture of the right femur. The client abruptly becomes intensely restless and confused, with a respiratory rate of 34 breaths per minute. Upon physical assessment, the nurse observes a new onset of petechiae over the client's anterior chest and axillae. Which of the following actions is the nurse's priority?

  1. A
    Assess the client's surgical dressing and thigh circumference for signs of hemorrhage.
  2. B
    Obtain equipment for an immediate arterial blood gas (ABG) draw to assess hypoxia.
  3. Administer high-flow supplemental oxygen via a non-rebreather mask.Answer
  4. D
    Turn the client onto the left lateral side and lower the head of the bed.

Answer

Administer high-flow supplemental oxygen via a non-rebreather mask.
The correct answer addresses the most immediate life-threatening consequence of Fat Embolism Syndrome: profound hypoxemia. The classic triad of FES includes hypoxemia, neurological abnormalities, and a petechial rash. According to the ABCs of prioritization, optimizing oxygenation with a non-rebreather mask is the initial and most critical nursing action to prevent respiratory arrest.

Step-by-Step Solution

1
Analyze the client's clinical presentation and recent history.
The client has a long bone fracture, new-onset restlessness, tachypnea (RR 34), and petechiae on the chest.
Identifying this specific cluster of symptoms is required to diagnose Fat Embolism Syndrome (FES) rather than a generalized complication like hemorrhagic shock.
2
Determine the physiological priority based on the diagnosis.
The primary threat to life in FES is severe hypoxemia leading to acute respiratory failure.
Applying the ABCs (Airway, Breathing, Circulation) framework dictates that respiratory compromise must be addressed before circulation or further diagnostic testing.
3
Select the most appropriate immediate intervention.
Applying high-flow oxygen via a non-rebreather mask is the critical first action.
Supplemental oxygen directly treats the life-threatening hypoxia before other supportive therapies or assessments are initiated.
