Final answer:
Exposure to Lewisite (L) can result in a range of symptoms from flu-like effects to gastrointestinal hemorrhage and organ failure. Recognition of symptoms is crucial due to the potential for long-term health complications and increased risk of premature mortality.
Step-by-step explanation:
Signs and Symptoms of Exposure to Lewisite (L)
Lewisite (L), a chemical warfare agent, has several distinct signs and symptoms of exposure. Initially, there may be a latent period of 4-8 hours where no symptoms are evident. However, once they appear, individuals exposed to Lewisite can experience flu-like symptoms, including nausea, cough, and dyspnea. Severe cases involve pulmonary edema within 18-24 hours of inhalation. Ingestion of Lewisite can lead to gastrointestinal hemorrhage, characterized by vomiting and bloody diarrhea, followed by liver and kidney failure. It is essential to recognize these symptoms early, as exposure to Lewisite and similar substances can lead to long-term health consequences, including heart or lung disease and increased risk of premature mortality. Short-term effects may exacerbate pre-existing conditions, resulting in more frequent medication use, hospital visits, and emergency department admissions.
