Which of the following physiological changes is most directly responsible for the increased risk of postural hypotension in elderly patients due to autonomic neuropathy?

Accepted Answer

A. Decreased baroreceptor sensitivity leading to impaired heart rate response to blood pressure changes — Postural hypotension in elderly patients with autonomic neuropathy is primarily due to impaired baroreceptor reflexes, which fail to appropriately adjust heart rate and vascular tone in response to changes in posture. While arteriosclerosis (B) contributes to vascular stiffness, it does not directly cause the autonomic dysfunction. Left ventricular hypertrophy (C) and reduced renin-angiotensin-aldosterone activity (D) are less directly linked to the acute drop in blood pressure upon standing.

In contrast, CLT often tolerates errors that do not impede communication, prioritizing fluency and meaning-making, and often uses delayed or indirect correction to avoid disrupting the communication flow. Options B, C, and D misrepresent the core principles of both methods.
