Chapter 15 The Gastrointestinal System Review Questions Questions
Question 1 of 5
Which of the following statements about the stomach is FALSE?
Correct Answer: C
Rationale: The correct answer is C because amino acids are not absorbed through the stomach wall; they are absorbed in the small intestine. In the stomach, gastric juices break down proteins into peptides. Option A is incorrect because the stomach secretes pepsin to digest proteins. Option B is also incorrect as pepsinogen is converted to pepsin for protein digestion. Option D is incorrect since ghrelin, the appetite hormone, is indeed released by the stomach.
Question 2 of 5
In preparing a client for a colonoscopy procedure, which task is most suitable to delegate to the nursing assistant?
Correct Answer: B
Rationale: Step 1: Delegation Principle - The task should be within the nursing assistant's scope of practice. Step 2: NPO reinforcement is a basic instruction that does not require clinical judgment. Step 3: Nursing assistant can remind the client about NPO status without interpreting medical information. Step 4: Administering laxatives (C) and enema (D) require clinical judgment and should be done by licensed staff. Step 5: Explaining the need for clear liquids (A) involves providing medical information, not just a reminder.
Question 3 of 5
A client with a GI disorder has to undergo a barium swallow test. Which of the following diet restrictions are required prior to the test?
Correct Answer: A
Rationale: The correct answer is A: NPO for 8 to 12 hours before the test. This is necessary to ensure the client's stomach is empty, allowing for clear visualization of the GI tract during the barium swallow test. NPO for a longer duration helps prevent any interference from food or liquids. Choice B is incorrect because 6-8 hours might not be sufficient for complete emptying of the stomach. Choice C is incorrect as maintaining normal fluid intake may lead to residual fluids in the stomach, affecting test accuracy. Choice D is unrelated to the test and does not impact the visualization of the GI tract.
Question 4 of 5
When monitoring the food intake of a client with Crohn's disease, the nurse observes that the client does not eat most of the food serve The nurse learns that the client finds the food unappetizing. Which of the following steps should the nurse take to address this issue?
Correct Answer: B
Rationale: The correct answer is B. Request the dietitian to suggest more acceptable food. This step is appropriate because it involves seeking help from a professional who can provide tailored dietary recommendations based on the client's preferences and restrictions. The dietitian can work with the client to identify foods that are both appetizing and suitable for managing Crohn's disease. Explanation for why the other choices are incorrect: A: Explaining the benefits of eating the prescribed food may not address the client's issue of finding the food unappetizing. C: Providing total parenteral nutrition and lipid infusions is an extreme measure and should only be considered when all other options have been exhausted. D: Providing elemental diet formula and 5-ASA medications may not address the client's immediate concern of finding the food unappetizing.
Question 5 of 5
A client with an ileostomy wants to know why to avoid fibrous vegetables. What should be the nurse's response?
Correct Answer: B
Rationale: The correct answer is B because fibrous vegetables can potentially cause stomal obstruction in clients with an ileostomy due to their indigestible nature, leading to blockages in the stoma. This can result in severe complications and require medical intervention. Gas formation (choice A) is a common issue with high-fiber foods but is not specific to fibrous vegetables. Fibrous vegetables are not necessarily difficult to digest (choice C) for most individuals, although they may be harder for those with reduced gut function. While fibrous vegetables may contribute to loose stools, they do not directly increase the risk of diarrhea (choice D) in the same way they can cause stomal obstruction.
