When there is stimulation of the sympathetic nervous system (SNS), blood is diverted away from the gastrointestinal (GI) tract. What might the nurse assess that would indicate this diversion of blood flow to the GI tract?

A) Decreased bowel sounds: When the sympathetic nervous system (SNS) is activated, such as during stress or a "fight-or-flight" response, blood is redirected away from the gastrointestinal (GI) tract to vital organs like the heart and muscles. This results in decreased gastrointestinal motility and function, which is reflected in a reduction in bowel sounds. Decreased bowel sounds are a direct consequence of reduced blood flow and decreased activity in the GI system. B) Increased blood glucose level: While it is true that SNS activation can lead to an increase in blood glucose due to the release of catecholamines (e.g., epinephrine), this response is related to the body’s preparation for physical exertion and not directly a result of blood being diverted from the GI tract. The increase in glucose levels is more about energy mobilization rather than an effect on blood flow to the GI tract. C) Decreased immune reaction: Sympathetic stimulation can indeed have effects on immune function, typically suppressing immune responses during a stress response. However, this is not directly linked to blood being diverted away from the GI tract. Immune suppression is more about the body prioritizing immediate survival (e.g., diverting energy to muscles for fight-or-flight) rather than a specific physiological consequence of GI blood flow changes. D) Increased blood pressure: Sympathetic nervous system activation does lead to an increase in blood pressure due to vasoconstriction and increased heart rate. However, increased blood pressure is a broader systemic response to SNS stimulation, and it is not directly related to blood being diverted from the GI tract. Blood pressure increases as part of the general "fight-or-flight" response, but it does not specifically indicate changes in GI blood flow.
