Neurogenic shock is characterized by:-
**Question:** Neurogenic shock is characterized by:-
A. Hypotension
B. Bradycardia
C. Cold, clammy skin
D. Hyperglycemia
**Core Concept:** Neurogenic shock is a type of shock caused by injury to the autonomic nervous system, primarily affecting the sympathetic division. It leads to a reduction in systemic vascular resistance and cardiac output, resulting in hypotension and bradycardia.
**Why the Correct Answer is Right:**
Neurogenic shock primarily involves the sympathetic division of the autonomic nervous system. This results in decreased systemic vascular resistance and cardiac output. Consequently, the body experiences hypotension and bradycardia.
**Why Each Wrong Option is Incorrect:**
A. Hypotension is indeed a feature of neurogenic shock, but the correct answer is "hypotension" rather than "hypertonia."
B. Bradycardia is another feature of neurogenic shock, but the correct answer is "bradycardia" rather than "tachycardia."
C. Cold, clammy skin is not a defining feature of neurogenic shock. Other shock types, such as cardiogenic shock, may present similarly.
D. Hyperglycemia is not a feature of neurogenic shock, as it is more commonly associated with other shock types like septic shock or hemorrhagic shock.
**Clinical Pearl / High-Yield Fact:**
Understanding the distinction between different types of shock (e.g., cardiogenic, hypovolemic, neurogenic, and septic) is crucial for accurate diagnosis and timely management.
**Correct Answer:**
Correct Answer: Hypotension, Bradycardia (Option A and B).
Neurogenic shock is a result of sympathetic nervous system dysfunction, leading to impaired cardiovascular responses and decreased cardiac output. This results in hypotension and bradycardia, which are the main features of neurogenic shock. The other options (C and D) are not specific to neurogenic shock and may also be seen in other types of shock, making them less specific and relevant to the correct answer.
