Zorluk: KolayPhysiological Adaptation

A nurse is assessing a postoperative client who recently underwent major abdominal surgery. Which clinical findings should indicate to the nurse that the client is experiencing the early, compensatory stage of hypovolemic shock? Select all that apply.

  1. Heart rate of 118 beats per minuteCevap
  2. B
    Systolic blood pressure of 74 mmHg
  3. Restlessness and apprehensionCevap
  4. D
    Bounding radial pulses
  5. Cool, pale skin on the extremitiesCevap

Cevap

The correct findings are a heart rate of 118 beats per minute, restlessness and apprehension, and cool, pale skin on the extremities.
In the early (compensatory) stage of hypovolemic shock, the body attempts to maintain adequate cardiac output and vital organ perfusion despite volume loss. This is achieved through sympathetic nervous system stimulation, which increases the heart rate (tachycardia) and causes peripheral vasoconstriction, leading to cool, pale extremities. Additionally, mild hypoxia to the brain causes early neurological changes such as restlessness, anxiety, or apprehension.

Adım Adım Çözüm

1
Analyze the client's condition and the stage of shock asked in the question.
The question asks specifically for signs of the 'early, compensatory stage' of hypovolemic shock.
Different stages of shock present with vastly different clinical symptoms. Focusing on early mechanisms is key.
2
Identify physiological responses during the compensatory stage.
The body activates the sympathetic nervous system to maintain blood pressure and perfusion to vital organs. This results in an increased heart rate, peripheral vasoconstriction, and mild hypoxia.
These compensatory mechanisms attempt to overcome the loss of circulating volume.
3
Evaluate each option against known early compensatory mechanisms.
Tachycardia, restlessness (from mild hypoxia), and cool/pale skin (from vasoconstriction) are early signs. Hypotension and bounding pulses are incorrect.
Eliminating late signs and pathophysiologically incorrect findings isolates the correct early indicators.
