Zorluk: OrtaPhysiological Adaptation

An orthopedic unit nurse is caring for a client who sustained a long bone fracture of the right leg yesterday. The client abruptly exhibits extreme restlessness and complains of shortness of breath. The nurse observes new-onset pinpoint red spots on the client's upper chest. The vital signs show a heart rate of 122 beats/min and a respiratory rate of 34 breaths/min. An arterial blood gas (ABG) analysis reveals pH=7.52pH = 7.52, PaCO2=26 mm Hg\text{PaCO}_2 = 26 \text{ mm Hg}, and PaO2=52 mm Hg\text{PaO}_2 = 52 \text{ mm Hg}. Which intervention should the nurse implement first?

  1. Apply a high-concentration oxygen delivery device.Cevap
  2. B
    Instruct the client to breathe slowly into a paper bag.
  3. C
    Administer a prescribed as-needed intravenous sedative.
  4. D
    Prepare a continuous infusion of sodium bicarbonate.

Cevap

Apply a high-concentration oxygen delivery device.
The client's presentation of a recent long bone fracture, respiratory distress, sudden agitation, and chest petechiae represents the classic clinical triad of Fat Embolism Syndrome. The ABG results demonstrate uncompensated respiratory alkalosis driven by severe hypoxemia. The absolute priority is to treat the life-threatening lack of oxygen by applying a high-concentration oxygen delivery device, which directly addresses the root cause of the client's physiological decompensation.

Adım Adım Çözüm

1
Analyze the clinical presentation.
The combination of a recent long bone fracture, sudden restlessness, respiratory distress, and chest petechiae strongly indicates Fat Embolism Syndrome (FES).
Recognizing this specific, life-threatening complication guides the prioritization of emergency interventions.
2
Interpret the arterial blood gas (ABG) results.
The ABG shows uncompensated respiratory alkalosis (pH=7.52pH = 7.52, low PaCO2\text{PaCO}_2) combined with severe hypoxemia (PaO2=52 mm Hg\text{PaO}_2 = 52 \text{ mm Hg}).
The severe hypoxemia is driving the client's tachypnea, which in turn causes the respiratory alkalosis by blowing off carbon dioxide.
3
Determine the highest priority nursing intervention.
Addressing the profound hypoxemia with high-flow oxygen takes precedence over correcting the acid-base imbalance or providing symptomatic relief.
According to the Airway-Breathing-Circulation (ABC) framework, resolving severe hypoxemia is the most immediate life-saving action.
