Toxic Shock Syndrome

Toxic shock syndrome is caused by bacterial superantigen toxins (TSST-1 from S. aureus or streptococcal pyrogenic exotoxins) that bypass normal antigen processing and activate massive T-cell proliferation. This triggers a cytokine storm causing widespread vasodilation, capillary leak, and multi-organ failure. Connect Toxic Shock Syndrome to bedside cues you will reassess first: vitals trends, work of breathing, perfusion, mentation, and pain or ischemic equivalents when relevant. Boards reward recognizing when subtle instability outweighs reassurance, then selecting nursing actions that protect airway, circulation, and neurologic status before routine tasks.
