Difficulty: EasyPhysiological Adaptation

An older adult client admitted with acute bronchitis has been resting comfortably. The practical nurse (PN) notes that the client has suddenly become highly restless and confused. Based on this sudden change, which of the following physiological conditions should the PN suspect first?

  1. Decreased tissue oxygenation (hypoxia)Answer
  2. B
    Normal progression of age-related dementia
  3. C
    Inadequate pain management
  4. D
    Mild systemic dehydration

Answer

Decreased tissue oxygenation (hypoxia)
The correct answer identifies hypoxia, because the brain is highly sensitive to drops in oxygen levels. In a client with a respiratory illness like bronchitis, early signs of decreased oxygenation often present as sudden neurological changes, specifically restlessness, agitation, and acute confusion.

Step-by-Step Solution

1
Analyze the client's baseline and current condition
The client has a respiratory infection (bronchitis) and has experienced a sudden onset of restlessness and confusion.
Identifying acute changes from baseline is critical for recognizing physiological deterioration.
2
Relate the symptoms to the most immediate life-threatening physiological alteration
Restlessness and confusion are early neurological indicators that the brain is not receiving enough oxygen.
In the context of a respiratory illness, impaired gas exchange leads to hypoxia, requiring immediate assessment and intervention.

Key Concept

Early signs of hypoxia include restlessness, agitation, and acute confusion.
