Chapter 44 : Introduction to the Gastrointestinal System and Accessory Structures Questions
Question 1 of 5
The nurse is preparing a client for magnetic resonance imaging (MRI) of the abdomen. Which statement by the client would indicate the need to notify the physician?
Correct Answer: B
Rationale: An MRI scanner is a narrow, tunnel-like machine that will enclose the client during the test. Clients who are claustrophobic (fear enclosed spaces) may need sedation because it is imperative that they lie still and not panic during the test.
Therefore, the nurse should notify the physician about the client's statement. Typically, the client is NPO for 6 to 8 hours before the test, and he or she must remove any metal objects, credit cards, jewelry, and watch before the test. Visualization will assist the client in relaxing during the procedure.
Question 2 of 5
The nurse is providing community education at the mall. The nurse is instructing on the muscular tube that connects the mouth to the stomach. The nurse outlines this structure on a drawing and labels it with which of the following?
Correct Answer: C
Rationale: The esophagus begins at the base of the pharynx and ends at the opening of the stomach. Layers of muscular tissue surround the esophagus. The pharynx is part of the throat situated immediately inferior to the mouth and nasal cavity. The pylorus is the region of the stomach that connects to the duodenum. The ileum is a portion of the small intestine.
Question 3 of 5
A nurse is employed as a gastroenterologist's office nurse. When assessing the client, which objective data would provide useful information for diagnosis?
Correct Answer: B
Rationale: The best objective data with useful information is the fact that the client has lost 22 pounds in 2 months, indicating significant weight loss in a short period of time. This is data that, with further questioning, could provide further details for diagnosis. A client verbalizing symptoms of nausea and pain constitutes subjective data. Viewing the client's seated posture offers little data.
Question 4 of 5
Which nursing instruction is correct to provide the client following a barium enema?
Correct Answer: B
Rationale: It is important to instruct the client that it is normal to have a white- or clay-colored stool following the barium enema. The client should report the color of the stool to the nurse. A progression of clay-colored stools to brown-colored stools should be noted. The client is prescribed a low-residue diet before the procedure. An increased fluid intake is offered to eliminate the barium from the bowel. The client is encouraged to move the bowel independently.
Question 5 of 5
The nurse is scheduling gastrointestinal (GI) diagnostic testing for a client. Which GI test should be scheduled first?
Correct Answer: A
Rationale: Radiography of the gallbladder should be performed before the other GI exams listed in which barium is used because residual barium tends to obscure the images of the gallbladder and its duct.
