Answer to Question 1

B
Feedback:
When blood is diverted away from the GI tract, bowel sounds decrease and digestion slows dramatically, sphincters are constricted, and bowel evacuation cannot occur. Increased blood glucose levels, elevated blood pressure, and decreased immune reaction are due to SNS stimulation but are not concerned with the GI tract.

Answer to Question 2

C, D, E
Feedback:
Laxative, or cathartic, drugs are indicated for the short-term relief of constipation; to prevent straining when it is clinically undesirable (such as after surgery, myocardial infarction, or obstetric delivery); to evacuate the bowel for diagnostic procedures; to remove ingested poisons from the lower gastrointestinal (GI) tract; and as an adjunct in anthelmintic therapy when it is desirable to flush helminths from the GI tract. They are not indicated when a patient has an appendicitis or a partial small-bowel obstruction.
