Difficulty: MediumPhysiological Adaptation

Following a complex cystoscopy procedure, a client develops a systemic infection. While performing a reassessment, the nurse notes several changes in the client's clinical presentation. Which assessment findings should alert the nurse that the client is experiencing the early, hyperdynamic phase of septic shock? Select all that apply.

Answer

The correct findings indicating early (hyperdynamic) septic shock are warm, flushed skin; a heart rate of 118 beats/min118\text{ beats/min}; and a respiratory rate of 28 breaths/min28\text{ breaths/min}.
During the early (hyperdynamic) phase of septic shock, inflammatory endotoxins cause massive systemic vasodilation. This lack of vascular resistance presents clinically as warm, flushed skin and a widened pulse pressure. To compensate for the loss of vascular tone and maintain tissue perfusion, the sympathetic nervous system initiates an increase in heart rate (tachycardia) and respiratory rate (tachypnea). Therefore, hyperthermia or flushed skin, a rapid heart rate, and increased respirations are classic early indicators that differentiate early septic shock from other shock states.

Step-by-Step Solution

1
Identify the phase of shock described in the clinical scenario.
The scenario specifies the 'early, hyperdynamic phase' of septic shock.
Different phases of shock present with distinct physiological signs, requiring precise recognition for proper intervention.
2
Recall the physiological mechanisms that characterize the hyperdynamic phase of septic shock.
This phase is characterized by the release of inflammatory mediators causing massive systemic vasodilation and a compensatory increase in cardiac output and respiratory effort.
Understanding the underlying pathophysiology allows you to predict the resulting clinical signs.
3
Evaluate each option to determine if it aligns with vasodilation and early compensatory mechanisms.
Vasodilation causes warm, flushed skin. Compensatory mechanisms cause an elevated heart rate (tachycardia) and elevated respiratory rate (tachypnea).
Matching physiological principles directly to assessment data distinguishes correct early indicators from late signs or distractors.
