Practice Question
A nurse and a newly licensed nurse are providing care for a client who has distributive shock related to an anaphylactic reaction. How should the nurse explain the pathophysiology of distributive shock to the newly licensed nurse?
Answer Choices:
Correct Answer:
"Distributive shock occurs due to systemic vasodilation."
Rationale:
🩸 Distributive shock, including anaphylactic, neurogenic, and septic shock, is caused by massive vasodilation leading to relative hypovolemia and decreased tissue perfusion.
🩸 In anaphylaxis, histamine release causes widespread vasodilation and increased capillary permeability.
🩸 This results in hypotension despite normal or increased blood volume, which impairs oxygen delivery.
🩸 The hallmark of distributive shock is vasodilation, not fluid loss or impaired contractility (which are seen in hypovolemic and cardiogenic shock).
