Gastrointestinal Test Questions Questions
Question 1 of 5
The following areas contain tonsils except which one?
Correct Answer: A
Rationale: Step-by-step rationale: 1. Tonsils are lymphoid tissues located in the oral and nasal pharynx, and the root of the tongue. 2. The frenulum is a small fold of tissue under the tongue, not known to contain tonsils. 3. Therefore, the area around the frenulum does not contain tonsils. Summary: A is correct because tonsils are not found around the frenulum. B, C, and D are incorrect as they are known locations of tonsils in the oral and nasal pharynx and the root of the tongue.
Question 2 of 5
Which area has the greatest amount of enzyme activity?
Correct Answer: A
Rationale: The duodenum has the greatest amount of enzyme activity among the choices given. This is because the duodenum is the first part of the small intestine where most digestion occurs. It receives bile from the liver and pancreatic enzymes, which aid in breaking down food molecules. The colon, jejunum, and ileum are parts of the small intestine but have less enzyme activity compared to the duodenum. The colon mainly absorbs water and electrolytes, while the jejunum and ileum are involved in nutrient absorption rather than enzyme activity. Therefore, the duodenum is the correct choice based on its role in digestion and enzyme secretion.
Question 3 of 5
Which part of the digestive system is primarily responsible for the absorption of water?
Correct Answer: B
Rationale: The large intestine is primarily responsible for the absorption of water in the digestive system. It reabsorbs water and electrolytes from the indigestible food residue, forming feces. The small intestine is more involved in nutrient absorption. The stomach mainly digests food, while the duodenum is the initial segment of the small intestine where most digestion occurs. The large intestine's main role in water absorption makes it the correct answer.
Question 4 of 5
A client who is scheduled for a barium swallow asks the nurse why a laxative is necessary following the procedure. Which of the following responses should the nurse make?
Correct Answer: B
Rationale: The correct answer is B: The laxative helps eliminate the barium. After a barium swallow, the client needs to expel the barium from their system to prevent barium toxicity. The laxative helps to move the barium through the digestive system and facilitate its elimination. Choices A, C, and D are incorrect because preventing magnesium absorption, facility protocol, and changing the color of barium are not reasons for the necessity of a laxative after a barium swallow.
Question 5 of 5
A nurse is assisting a group of clients in an outpatient clinic. For which of the following clients should the nurse anticipate scheduling a colonoscopy?
Correct Answer: C
Rationale: The correct answer is C because having a first-degree relative who died of colon cancer puts the client at an increased risk for developing colon cancer. This indicates the need for a colonoscopy for early detection and preventive measures. A: A 56-year-old who had a colonoscopy 6 years ago is not a priority for immediate scheduling. B: A 34-year-old with new onset constipation may require further assessment but not necessarily a colonoscopy. D: A 51-year-old attending an annual physical exam without additional risk factors does not warrant immediate colonoscopy.
