The nurse is caring for a client with pneumonia who now develops initial signs of septic shock and multi-organ failure. The healthcare provider prescribes a sepsis protocol. Which intervention is most important for the nurse to include in the plan of care?

A. Raising the head of the bed can help improve lung expansion and reduce aspiration risk, which is beneficial for a client with pneumonia. However, while this intervention supports respiratory function, it does not directly address the systemic perfusion and organ failure risks associated with septic shock. Therefore, it is not the highest priority intervention in a sepsis protocol. B. Blood glucose monitoring is important in sepsis because stress-induced hyperglycemia is common and uncontrolled glucose can worsen outcomes. However, this intervention is supportive rather than critical in the early management of septic shock and does not take priority over interventions that directly evaluate perfusion and organ function. C. Strict intake and output monitoring is essential in septic shock because it provides immediate information about renal perfusion and fluid balance. Septic shock causes widespread vasodilation and capillary leak, leading to decreased organ perfusion and acute kidney injury. Urine output is a key indicator of organ function and response to fluid resuscitation, making this intervention a core component of sepsis management. D. Assessing extremity warmth helps evaluate peripheral perfusion and can indicate early versus late septic shock. While this is a useful assessment, it is less critical than objective measures such as urine output that directly reflect organ perfusion and guide treatment decisions.
