Chapter 44 : Introduction to the Gastrointestinal System and Accessory Structures Questions
Question 1 of 5
The nurse is instructing the client who was newly diagnosed with peptic ulcers. Which of the following diagnostic studies would the nurse anticipate reviewing with the client?
Correct Answer: B
Rationale: Helicobacter pylori, a bacterium, is believed to be responsible for the majority of peptic ulcers. Blood tests are used to determine whether there are antibodies to H. pylori in the blood. A complete blood count with differential can indicate bleeding and infection associated with a bleeding ulcer. A sigmoidoscopy assesses the lower gastrointestinal tract. Gastric analysis is more common in analyzing gastric fluid in determining problems with the secretory activity of the gastric mucosa.
Question 2 of 5
The nurse is caring for a client following a colonoscopy. During the procedure, two medium-sized polyps were removed. Which nursing assessment in the recovery area is a priority?
Correct Answer: C
Rationale: The nurse is correct in assessing vital signs following a colonoscopy with polyp removal as a priority. Vital signs of an increased pulse rate and falling blood pressure can indicate a perforation and bleeding. If a perforation occurs and is not addressed at an early stage, the client's level of consciousness can become affected. There would be no reliable stool present in the bowel to Hemoccult test due to the cleansing agent and potential bleeding from the polyp removal. The ability to tolerate fluids relates to the sedation process and is not as high of a priority.
Question 3 of 5
The nurse is examining the skin of a client who is dehydrated due to fluid losses from the gastrointestinal tract. Which would be the most important assessment for the nurse to make?
Correct Answer: B
Rationale: Mucous membranes may be dry, and skin turgor may be poor in clients suffering from dehydration as a result of fluid losses from the GI tract. Checking the skin for discoloration and inspecting the sclera if it is yellow is taken into consideration when the client could have symptoms of jaundice, not fluid losses. Distended abdominal veins are not associated with dehydration.
Question 4 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 5 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.
