Difficulty: EasyPhysiological Adaptation

Following an admission for severe pneumonia, a client's clinical status begins to deteriorate. Which of the following initial assessment findings should alert the nurse to the early development of septic shock?

  1. Warm, flushed skin with a bounding pulseAnswer
  2. B
    Cool, clammy skin with a weak, thready pulse
  3. C
    A sudden, significant elevation in blood pressure
  4. D
    A marked decrease in the respiratory rate

Answer

Warm, flushed skin with a bounding pulse
The early phase of septic shock, known as the 'warm phase,' is characterized by a hyperdynamic cardiovascular response. Systemic inflammatory mediators cause massive vasodilation, resulting in warm, flushed skin, tachycardia, and bounding pulses. This is a unique physiological adaptation distinct from the initial presentations of other shock types.

Step-by-Step Solution

1
Analyze the client's condition and the specific stage of the complication being asked.
The client has severe pneumonia and is at risk for septic shock. The question specifically asks for 'early' signs.
Different stages of shock present with distinct physiological signs.
2
Recall the pathophysiology of early septic shock.
Early septic shock is unique because endotoxins cause massive systemic vasodilation while the heart initially compensates by pumping harder (hyperdynamic state).
Understanding the mechanism helps differentiate early septic shock from hypovolemic or cardiogenic shock.
3
Correlate the pathophysiological changes with observable clinical findings.
Massive vasodilation with high cardiac output manifests clinically as warm, flushed skin, tachycardia, and a bounding pulse.
This contrasts with the late phase of shock, where the heart begins to fail and the skin becomes cold and clammy.
