Answer to Question 1

B
Feedback:
The peritoneum lines the abdominal wall and viscera and helps keep the GI tract in place and prevents a buildup of friction with movement. The muscularis mucosa layer helps propel the GI contents downward. The nerve plexus helps to slow the GI tract when digestion is not a priority or stimulates it for digestion. The adventitia serves as a supportive layer and helps the tube maintain its shape.

Answer to Question 2

C
Feedback:
The nurse should instruct the patient to take a sip of water to moisten the mucous membranes so the tablet will dissolve quickly. The patient does not need to take his pulse or lie down before drug administration. For sublingual administration, the patient will place the tablet under his tongue and not in the buccal cavity (cheek area).
