After exposure to TIH or other toxic inhalants, which symptom may be delayed?

• A. Headache
• B. Rash
• C. Nausea
• D. Diarrhea

Answer: (A)

TIH exposures can produce effects that don’t show up immediately. Some inhaled toxicants cause injury that develops over time, so you can see symptoms appear hours after the initial exposure. Headache fits this pattern because CNS effects or evolving hypoxia from developing lung injury can become noticeable later, even if the person felt only mild symptoms at first. Nausea, diarrhea, and rash are less likely to be delayed after inhaling toxic inhalants. Nausea and diarrhea are more commonly tied to ingestion or rapidly systemic effects, and a rash isn’t a typical late-developing sign of inhalation injury unless a specific sensitization or skin reaction is involved. So the symptom that may surface after a delay is headache.
