Which of the following is NOT a symptom of cyanide poisoning?

Cyanide poisoning manifests with specific symptoms due to the way the toxin affects cellular respiration. The presence of confusion, shortness of breath, and seizures aligns with the physiological impact of cyanide, which inhibits the body’s ability to utilize oxygen effectively.

Confusion can arise as the brain is deprived of adequate oxygen, leading to neurological disturbances. Shortness of breath is another critical symptom, as the body attempts to compensate for the lack of oxygen at the cellular level. Seizures may occur due to severe hypoxia affecting brain function.

In contrast, red itchy skin is not a recognized symptom of cyanide poisoning. While skin reactions can occur due to various toxins or irritants, they are not typical for cyanide exposure. Thus, choosing red itchy skin highlights a misunderstanding of the specific clinical presentation of cyanide toxicity.
