Gastrointestinal NCLEX Questions Questions
Question 1 of 5
Hepatocytes or hepatic cells produce bile, which is secreted into the
Correct Answer: B
Rationale: The correct answer is B: bile canaliculi. Hepatocytes produce bile, which is then secreted into bile canaliculi within the liver. From there, bile flows into bile ducts and eventually reaches the gallbladder or small intestine. The other options are incorrect because bile is not secreted directly into the hepatic portal vein (A), hepatic sinusoid (C), or lacteal (D). The hepatic portal vein carries blood from the digestive organs to the liver, the hepatic sinusoid is a type of blood vessel within the liver, and lacteals are lymphatic vessels in the small intestine.
Question 2 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 3 of 5
Which one of the following tissues normally DOES NOT produce ghrelin that stimulates food intake?
Correct Answer: D
Rationale: Step 1: Ghrelin is primarily produced by the stomach to stimulate appetite. Step 2: The pancreas produces insulin and enzymes, not ghrelin. Step 3: The adrenal glands produce hormones like cortisol, not ghrelin. Step 4: The liver is not a major site for ghrelin production, making choice D the correct answer.
Question 4 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 5 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.
