In nux vomica poisoning the following are also required to be preserved –
**Core Concept**
Poisoning with nux vomica, the seed of the Apocynum plant, presents a medical emergency due to its toxic alkaloids, particularly strychnine. The clinical presentation and management of nux vomica poisoning are critical to prevent severe outcomes.
**Why the Correct Answer is Right**
In nux vomica poisoning, it is crucial to preserve the stomach contents, urine, and feces for toxicological analysis. This is because the alkaloids, such as strychnine and brucine, can be detected in these bodily secretions, which helps in confirming the diagnosis and estimating the dose ingested. Preserving these samples also aids in determining the effectiveness of treatment and in investigating potential cases of poisoning.
**Why Each Wrong Option is Incorrect**
**Option A:** Blood samples are not typically preserved in nux vomica poisoning as the alkaloids are rapidly metabolized and their detection in blood is not reliable.
**Option B:** Hair samples may not be relevant in acute nux vomica poisoning, as the alkaloids may not be detectable in hair within a short time frame.
**Option C:** Nasal secretions are not commonly preserved in nux vomica poisoning, as they are not a reliable source of toxicological analysis.
**Clinical Pearl / High-Yield Fact**
In cases of suspected nux vomica poisoning, it is essential to obtain a detailed history of the substance ingested, including the amount and time of ingestion, as this information is critical for determining the appropriate management and prognosis.
**Correct Answer: C. Feces.**
