Chapter 44 : Introduction to the Gastrointestinal System and Accessory Structures Questions
Question 1 of 5
The instructor has just finished teaching a group of students about the various organs of the upper gastrointestinal tract and possible disorders. The instructor determines that the teaching was successful when the students identify which structure as possibly being affected?
Correct Answer: C
Rationale: The upper gastrointestinal (GI) tract begins at the mouth and ends at the jejunum.
Therefore, the stomach would be a component of the upper GI tract. The lower GI tract begins at the ileum and ends at the anus. The liver is considered an accessory structure.
Question 2 of 5
The nurse is preparing to measure the client's abdominal girth as part of the physical examination. At which location would the nurse most likely measure?
Correct Answer: B
Rationale: Measurement of abdominal girth is done at the widest point, which is usually the umbilicus. The right upper quadrant, lower border of the liver, or just below the last rib would be inappropriate sites for abdominal girth measurement.
Question 3 of 5
The nurse is working with clients with digestive tract disorders. Which organ does the nurse realize has effects as an exocrine gland and an endocrine gland?
Correct Answer: B
Rationale: The pancreas is both an exocrine gland, one that releases secretions into a duct or channel, and an endocrine gland, one that releases substances directly into the bloodstream. The other organs have a variety of functions but do not have a combination function such as the pancreas.
Question 4 of 5
The nurse is instructing the client on sensations commonly experienced when a contrast agent is injected into the body during diagnostic studies. Which sensation is most common?
Correct Answer: B
Rationale: The nurse informs the client of the potential to experience a warm sensation and nausea when the contrast agent is instilled. The client is instructed to take a couple of deep breaths, and, many times, the sensation will go away. The other options are not frequently encountered.
Question 5 of 5
The nurse is accompanying the client to the diagnostic imaging unit for a magnetic resonance imaging (MRI). Which action by the nurse is most important prior to the test?
Correct Answer: B
Rationale: It is most important that the nurse calculate the drip rate of the intravenous fluids because the client will not be able to have an electrical or mechanical pump operating during the MRI. The MRI electrical charges during the test can affect the pump. It is also important to advise the client of the loud noises and offer support to the client. Water is typically not available in the waiting area prior to testing.
