Gastrointestinal NCLEX Questions Questions
Question 1 of 5
The function of the gastrointestinal tract can be classified in several ways. Which of the following functions is most important for survival immediately after a meal?
Correct Answer: A
Rationale: The correct answer is A: Absorption and retention of water and electrolytes. Immediately after a meal, the body needs to absorb water and electrolytes to maintain proper hydration and electrolyte balance, crucial for survival. This process helps in nutrient absorption and maintaining overall body function. Reasons for why the other choices are incorrect: B: Elimination of toxins - While important for overall health, elimination of toxins is not the most critical function immediately after a meal for survival. C: Maintenance of barrier function - While important for protecting against harmful substances, it is not the most vital function immediately after a meal for survival. D: Extraction of maximum value from nutrients - While important for optimal nutrition, it is not as crucial as absorption and retention of water and electrolytes for immediate survival post-meal.
Question 2 of 5
Which of the following would likely promote the development of obesity?
Correct Answer: D
Rationale: The correct answer is D because an increase in hypothalamic neuropeptide Y and agouti-related protein can lead to increased appetite, reduced energy expenditure, and ultimately promote the development of obesity. Neuropeptide Y stimulates food intake, while agouti-related protein inhibits the regulation of food intake and energy expenditure. A is incorrect because a greater proportion of bacteriabetes relative to firmicutes gut microflora is not directly linked to the development of obesity. B is incorrect because a smaller dopamine response to high fat and sugar foods would likely lead to reduced intake, not obesity. C is incorrect because a smaller increase in ghrelin concentrations would lead to decreased appetite, which is not conducive to obesity development.
Question 3 of 5
In caring for a client with GERD, which task would be appropriate to assign to the nursing assistant?
Correct Answer: C
Rationale: The correct answer is C because reminding the client not to lie down after eating helps prevent acid reflux in GERD. Nursing assistants can provide this basic instruction to promote client safety. Choice A involves sharing strategies that require more in-depth knowledge, not within a nursing assistant's scope. Choice B involves addressing emotional concerns, typically handled by nurses. Choice D involves explaining the rationale, which requires more understanding of the condition, beyond a nursing assistant's role.
Question 4 of 5
Which of the following routes is used to instill a dye for a radionuclide imaging test?
Correct Answer: A
Rationale: The correct answer is A because instilling a dye for radionuclide imaging test involves injecting the dye intravenously or orally to allow it to circulate in the bloodstream and be absorbed by the body tissues. IV route ensures rapid and direct entry into the bloodstream for proper distribution. Choices B, C, and D are incorrect as they do not provide the necessary direct access to the bloodstream required for effective distribution of the dye for imaging purposes.
Question 5 of 5
A nurse enters the room of a client with cramping, bloating, and flatus, as well as diarrhea and/or constipation, with or without the presence of mucus. What condition do the client's symptoms represent?
Correct Answer: B
Rationale: The correct answer is B: Irritable bowel syndrome. The symptoms described align with the criteria for diagnosing IBS, such as cramping, bloating, and changes in bowel habits. Peritonitis (A) is characterized by severe abdominal pain, fever, and rigidity. Ulcerative colitis (C) presents with bloody diarrhea and abdominal pain. Appendicitis (D) typically causes localized right lower quadrant pain, nausea, and vomiting. Therefore, based on the given symptoms, IBS is the most likely diagnosis.
