Which symptoms are part of the triad for severe cyanide toxicity?

The correct answer identifies the crucial symptoms associated with severe cyanide toxicity. Hypotension, altered mental status, and lactic acidosis represent important indicators that may arise in response to cyanide exposure.

Hypotension occurs due to the disruption of cellular respiration and overall metabolic function, leading to inadequate blood flow and oxygen delivery to tissues. This often results from the impact of cyanide on the cardiovascular system, as it inhibits the body’s ability to utilize oxygen even when it is present.

Altered mental status is another key symptom. This can manifest as confusion, agitation, or decreased responsiveness, reflecting the central nervous system's sensitivity to cyanide's effects. The brain relies heavily on proper oxygenation, and when cellular respiration is impaired, neurological deficits may quickly become apparent.

Lactic acidosis occurs due to anaerobic metabolism, a consequence of the cells' inability to process oxygen. In severe cases of cyanide toxicity, the body shifts to producing energy without oxygen, resulting in the accumulation of lactic acid and subsequently causing a metabolic acidosis, which can further complicate the clinical picture.

Overall, these symptoms form a triad that highlights the profound physiological disturbances caused by cyanide toxicity and emphasizes the need for immediate intervention and treatment to restore normal cellular
