What is included in the triad of symptoms for neurogenic shock?

The triad of symptoms for neurogenic shock typically includes hypotension and peripheral vasodilation as key components. Neurogenic shock occurs when there is a loss of sympathetic tone due to a spinal cord injury or severe central nervous system insult. This results in a marked decrease in vascular resistance, leading to peripheral vasodilation. The vasodilation causes blood to pool in the extremities, contributing to hypotension.

Furthermore, as the blood vessels dilate and blood pressure decreases, the heart rate does not always increase to compensate, which can contrast with other forms of shock where tachycardia is common. Instead, bradycardia may occur due to unopposed vagal tone, but this is more of a secondary effect rather than primary symptomatology.

The other choices either describe symptoms not typical of neurogenic shock or present conflicting symptoms that do not align with the expected physiological response to neurogenic shock. Thus, hypotension and peripheral vasodilation accurately encapsulate the characteristic features of this condition, which is why this answer is correct.
