Zorluk: OrtaPhysiological Adaptation

While caring for a client who is receiving intravenous antibiotics for acute pyelonephritis, the nurse monitors for systemic complications. Which assessment finding provides the earliest physiological indication that the client is developing septic shock?

  1. Warm, flushed skin accompanied by a respiratory rate of 28 breaths/minuteCevap
  2. B
    Mottled, cool extremities with a weak, thready radial pulse
  3. C
    Arterial blood gas values indicating a pH of 7.32 and a PaCO2 of 50 mm Hg
  4. D
    A temperature elevation from 38.1°C (100.6°F) to 38.8°C (101.8°F)

Cevap

Warm, flushed skin accompanied by a respiratory rate of 28 breaths/minute.
In the early (hyperdynamic or 'warm') phase of septic shock, the release of inflammatory mediators causes widespread peripheral vasodilation, resulting in warm, flushed skin. Concurrently, the body compensates by increasing the respiratory rate to maximize tissue oxygen delivery, manifesting as early tachypnea. These subtle indicators often precede the classic signs of severe hypotension and cool extremities.

Adım Adım Çözüm

1
Analyze the clinical scenario.
The client has a severe bacterial infection (pyelonephritis) and is at risk for progressing to septic shock.
Identifying the primary risk factor helps anticipate the specific pathophysiological changes associated with that complication.
2
Identify the earliest physiological changes of septic shock.
Early septic shock (hyperdynamic phase) features massive peripheral vasodilation and a compensatory increase in cardiac output and respiratory rate.
Unlike other forms of shock, the initial phase of distributive shock presents with signs of high cardiac output before progressing to hypoperfusion.
3
Evaluate the options against early shock presentation.
Warm/flushed skin and tachypnea align with early vasodilation. Cool extremities indicate late shock. Respiratory acidosis contradicts early hyperventilation. Fever alone is an expected sign of infection.
Comparing all choices ensures the selected finding represents the earliest systemic hemodynamic decompensation.
