In the AEIOU mnemonic, which component corresponds to ingestion of toxins?

• A. Acidosis
• B. Electrolyte
• C. Ingestion/Intoxicants
• D. Uremic symptoms

Answer: (C)

AEIOU is used in emergency evaluation of altered mental status to quickly recall major categories of causes. The component that covers ingestion of toxins corresponds to Ingestion/Intoxicants, which groups together overdoses and exposure to ingested poisons such as alcohol, sedatives, opioids, acetaminophen, carbon monoxide, methanol, and other toxic ingestions. This category is the go-to reminder that substances taken into the body can acutely disrupt brain function and cause coma or confusion, often in a reversible way if identified and treated promptly. The other options describe metabolic disturbances or organ-system failures that contribute to altered mental status but are not the toxin-ingestion category highlighted in AEIOU.
