Final answer:
Neurogenic shock is a type of vascular shock associated with damage to the nervous system due to spinal or cranial injuries, characterized by decreased vascular resistance, and is often managed with vasopressor therapy.
Step-by-step explanation:
Neurogenic shock refers to a type of shock caused by the sudden loss of signals from the sympathetic nervous system that controls vascular tone. The correct answer related to neurogenic shock among the options provided is:
D. Due to decreased vascular resistance
Neurogenic shock results from the disruption of sympathetic nervous system signals, leading to vasodilation and decreased vascular resistance. This causes a sudden drop in blood pressure and can lead to inadequate tissue perfusion and oxygenation.
Some of the characteristics of neurogenic shock include hypotension, bradycardia, and peripheral vasodilation. Initial management often involves stabilizing the patient's blood pressure and restoring vascular tone. While vasopressor therapy may be used in some cases, the primary goal is often to address the underlying cause and restore sympathetic nervous system function.
