**Question:** Earliest feature of dhatura poisoning -
A. Nausea and vomiting
B. Diarrhoea
C. Sweating
D. Delirium
**Core Concept:** Dhatura poisoning is a condition caused by consuming Dhatura plant, which is a toxic plant found in some regions. Dhatura contains cardiac glycosides, which interfere with the normal functioning of the heart and nervous system.
**Why the Correct Answer is Right:** The correct answer, D. Delirium, is a result of cardiac glycosides' effect on the central nervous system (CNS). Delirium is characterized by a disturbance in attention, cognition, and awareness, which can be observed as an early symptom of Dhatura poisoning.
**Why Each Wrong Option is Incorrect:**
A. Nausea and vomiting are common gastrointestinal (GI) symptoms triggered by the cardiac glycosides' effect on the smooth muscles of the GI tract, not due to cardiac glycosides' direct impact on the CNS.
B. Diarrhoea is a GI symptom that occurs due to the direct action of cardiac glycosides on the smooth muscles of the colon, not specifically related to Dhatura poisoning.
C. Sweating is a general physiological response to fever or stress and does not specifically indicate Dhatura poisoning.
**Clinical Pearl:** The correct answer, Delirium, highlights the importance of recognizing the early neurological symptoms in poisoning cases. In clinical practice, it is crucial to promptly identify the cause of these symptoms to initiate timely and appropriate treatment.
**Correct Answer:** D. Delirium

**Core Concept:** Dhatura poisoning is a consequence of consuming the Dhatura plant, which contains cardiac glycosides that interfere with the normal functioning of the heart and nervous system.
**Why the Correct Answer is Right:** Delirium is a manifestation of the central nervous system (CNS) involvement in Dhatura poisoning. The cardiac glycosides interfere with the normal functioning of the heart and nervous system, leading to symptoms like delirium.
**Why Each Wrong Option is Incorrect:**
A. Nausea and vomiting are GI symptoms caused by the cardiac glycosides affecting the smooth muscles of the gastrointestinal tract, not specifically related to Dhatura poisoning.
B. Diarrhoea is a GI symptom resulting from cardiac glycosides' direct impact on the smooth muscles of the colon, not directly related to Dhatura poisoning.
C. Sweating is a general physiological response to fever or stress and is not a specific indicator of Dhatura poisoning.
**Clinical Pearls:**
1. In clinical practice, it is essential to recognize early neurological symptoms like delirium in poisoning cases to promptly initiate appropriate treatment.
2. Cardiac glycosides are involved in various poisoning cases, not just Dhatura poisoning, and can affect the heart, GI tract, or CNS.
**Correct Answer:** D. Delirium
