The patient is admitted with constipation. In anticipation of treatment, the nurse prepares to:
a. give medications that will suppress the autonomic nervous system.
b. provide therapies that will innervate the autonomic nervous system.
c. teach the patient that the submucosa is the innermost part of the gut wall.
d. give medications intravenously since the submucosa has no blood vessels.
B
The second layer of the gut wall, the submucosa, is composed of connective tissue, blood vessels, and nerve fibers. Beneath the mucosa, submucosa, and muscular layer are various nerve plexuses that are innervated by the autonomic nervous system. Disturbances in these neurons in a given segment of the GI tract cause a lack of motility. Therapies innervating the autonomic nervous system are thus appropriate. The muscular layer is the major layer of the wall. The serosa is the outermost layer.
