1. Question 1
   A patient stands up quickly and their blood pressure briefly drops. Which autonomic response helps restore blood pressure as part of the baroreceptor reflex?

   Increased somatic motor neuron firing to skeletal muscles, directly constricting arteriolesIncreased parasympathetic stimulation to the heart, decreasing heart rateIncreased sympathetic stimulation to the heart and blood vessels, increasing heart rate and vasoconstrictionDecreased sympathetic stimulation to arterioles, causing vasodilation

2. Question 2
   A patient has a sudden rise in arterial blood pressure. Which autonomic response is most likely to help restore homeostasis via the baroreceptor reflex?

   Increased parasympathetic (vagal) output to the heart, decreasing heart rateIncreased sympathetic stimulation to the SA node, increasing heart rateDecreased parasympathetic (vagal) output to the heart, increasing heart rateIncreased sympathetic stimulation to arterioles, causing vasoconstriction

3. Question 3
   A patient walks into a warm room and begins sweating to maintain a stable core temperature. Which autonomic response directly supports this thermoregulatory homeostasis?

   Parasympathetic stimulation of peripheral blood vessels, causing vasoconstrictionSympathetic stimulation of eccrine sweat glands, increasing sweat productionParasympathetic stimulation of eccrine sweat glands, increasing sweat productionSomatic motor neuron activation of arrector pili muscles, increasing heat loss

4. Question 4
   A patient’s pupils constrict when moving from a dark hallway into a brightly lit room. Which autonomic response helps maintain homeostasis in this situation?

   Sympathetic stimulation of the radial iris muscle causing pupil dilationSomatic motor stimulation of extraocular muscles to reduce light entrySympathetic stimulation of ciliary muscles to increase lens curvature for near visionParasympathetic stimulation of the sphincter pupillae muscle causing pupil constriction

   Check Answer
5. Question 5
   A hospitalized patient develops nausea shortly after eating. Which autonomic response would most directly support homeostasis by promoting digestion in the gastrointestinal tract?

   Somatic motor neuron activation that increases skeletal muscle tone in the abdominal wallSympathetic activation that decreases intestinal motility and constricts splanchnic blood vesselsParasympathetic activation that increases intestinal peristalsis and stimulates digestive secretionsActivation of the adrenal medulla to release epinephrine, increasing metabolic rate
