A nurse is evaluating a client who is 33 days post-operative following an exploratory laparotomy for a perforated appendix. The client appears restless and has warm, flushed skin.

Based on these findings, which intervention should the nurse perform first?

  1. Rapidly infuse a prescribed intravenous bolus of isotonic crystalloid solution.Cevap
  2. B
    Initiate a prescribed continuous intravenous infusion of norepinephrine.
  3. C
    Administer prescribed intravenous acetaminophen to reduce the fever.
  4. D
    Coach the client to take slow, deep breaths to decrease the respiratory rate.

Cevap

Rapidly infuse a prescribed intravenous bolus of isotonic crystalloid solution.
The client is experiencing early (hyperdynamic) septic shock, evidenced by profound hypotension, tachycardia, fever, and warm, flushed skin following an intra-abdominal infection. The ABG results indicate a severe metabolic acidosis (pH 7.277.27, HCO₃⁻ 14 mEq/L14\text{ mEq/L}) with appropriate respiratory compensation (PaCO₂ 29 mm Hg29\text{ mm Hg}). The metabolic acidosis is a result of lactic acid accumulation from systemic tissue hypoperfusion. According to sepsis management guidelines, the absolute first priority to restore tissue perfusion and clear the lactic acidosis is aggressive intravascular volume resuscitation with an isotonic crystalloid bolus.

Adım Adım Çözüm

1
Evaluate the client's vital signs and physical assessment findings in the context of recent abdominal surgery.
The client demonstrates profound hypotension (84/42 mm Hg84/42\text{ mm Hg}), tachycardia, fever, and warm, flushed skin.
To identify the onset of a life-threatening complication, specifically early hyperdynamic septic shock resulting from the perforated appendix.
2
Analyze the arterial blood gas (ABG) values.
The ABG reveals a metabolic acidosis (pH 7.277.27, HCO₃⁻ 14 mEq/L14\text{ mEq/L}) with appropriate respiratory compensation (PaCO₂ 29 mm Hg29\text{ mm Hg}).
To determine the systemic impact of the shock state and ensure the respiratory system is appropriately attempting to compensate.
3
Correlate the metabolic acidosis with the clinical presentation to identify the root cause.
The acidosis is identified as lactic acidosis resulting from widespread tissue hypoperfusion caused by the septic shock state.
To ensure interventions target the underlying physiological failure (hypoperfusion) rather than simply attempting to correct the abnormal lab numbers.
4
Select the highest priority nursing intervention according to established sepsis protocols.
Aggressive fluid resuscitation with an isotonic crystalloid bolus is prioritized.
Intravascular volume expansion is the absolute first step required to restore mean arterial pressure, deliver oxygen to tissues, and halt the production of lactic acid.
