All of the following features are associated with Delirium tremens EXCEPT
**Core Concept**
Delirium tremens (DTs) is a severe form of alcohol withdrawal characterized by altered mental status, disorientation, and hallucinations. It typically occurs 48-72 hours after the last drink in individuals with a history of chronic alcohol use.
**Why the Correct Answer is Right**
Delirium tremens is a life-threatening condition that requires prompt medical attention. The pathophysiology involves an abrupt cessation of alcohol, leading to a surge in glutamate and a decrease in GABA levels in the brain. This imbalance results in hyperexcitability of neurons, causing the characteristic symptoms of DTs. The clinical features of DTs include:
* Altered mental status, ranging from confusion to coma
* Disorientation to time, place, and person
* Hallucinations, which can be visual, auditory, or tactile
* Severe anxiety and agitation
* Tachycardia and hypertension
* Diaphoresis and tremors
**Why Each Wrong Option is Incorrect**
**Option A:** This feature is actually associated with DTs, as patients often exhibit agitation, aggression, and combativeness.
**Option B:** This option is also incorrect, as DTs typically occur within 48-72 hours after the last drink, not immediately after cessation.
**Option C:** This feature is a hallmark of DTs, as patients often experience severe anxiety, agitation, and hallucinations.
**Clinical Pearl / High-Yield Fact**
The "classic" features of DTs include the "three Ts": tremors, tachycardia, and tingling. However, the most critical aspect of DTs is the presence of altered mental status, which requires prompt recognition and treatment to prevent serious complications.
**Correct Answer:**
