Final answer:
In the context of neurogenic shock, a patient is LEAST likely to present with tachycardia because this type of shock typically results in bradycardia due to decreased sympathetic tone from damage to the nervous system.
Step-by-step explanation:
A patient with neurogenic shock would be LEAST likely to present with tachycardia. Neurogenic shock is a form of vascular shock and occurs when there is damage to the cardiovascular centers in the medulla oblongata or the nervous fibers originating from this area, often resulting from cranial or spinal injuries.
Unlike other forms of shock where there is usually an increase in heart rate, in neurogenic shock, there is typically bradycardia, which is a slower-than-normal heart rate. Thus, tachycardia, or an abnormally rapid heartbeat, is not commonly seen in neurogenic shock. However, symptoms such as hypotension (low blood pressure), altered mentation (changes in mental status), and potentially tachypnea (rapid breathing) can be present. The decreased sympathetic tone due to injury results in vasodilation, which can lead to hypotension.
