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?
- A. Liver
- B. Ileum
- C. Stomach
- D. Large Intestine
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.

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?
- A. A complete blood count including differential
- B. Serum antibodies for H. pylori
- C. A sigmoidoscopy
- D. Gastric analysis
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.
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?
- A. Gallbladder
- B. Pancreas
- C. Stomach
- D. Liver
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.
The nurse is caring for a client experiencing diarrhea. When teaching about the site in the body where water and electrolytes are absorbed, the nurse is most correct to instruct on which location?
- A. The small intestine

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?
- A. I haven't had anything to eat or drink since midnight last night.
- B. I really don't like to be in small, enclosed spaces.
- C. I left all my jewelry and my watch at home.
- D. I will practice visualization to remain relaxed during the procedure.
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.
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?
- A. In the right upper quadrant
- B. At the umbilicus
- C. At the lower border of the liver
- D. Just below the last rib
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.
