Gastrointestinal System Nursing Exam Questions Questions
Question 1 of 5
Which single statement below, about the stomach, is actually correct?
Correct Answer: D
Rationale: The correct answer is D because pepsinogen and gastric lipase are indeed two enzymes secreted into the lumen of the stomach. Pepsinogen is converted to pepsin, an enzyme that breaks down proteins, while gastric lipase helps in the digestion of fats. A is incorrect because carbonic anhydrase is not a hormone but an enzyme involved in acid secretion. B is incorrect because Peyer's patches are actually found in the small intestine, not the stomach, and they are involved in the immune system. C is incorrect because the vagus nerve stimulates, rather than inhibits, acid secretion in response to a meal. In summary, D is correct as it accurately describes enzymes secreted in the stomach, while the other choices contain factual inaccuracies about stomach function.
Question 2 of 5
Which neurotransmitter is involved in the regulation of many of the secretory cells of the gastric (stomach) mucosa?
Correct Answer: C
Rationale: The correct answer is C: acetylcholine. Acetylcholine is involved in regulating secretory cells in the gastric mucosa by stimulating the release of gastric acid and enzymes. Norepinephrine and dopamine are not directly involved in gastric secretions. Insulin is a hormone involved in glucose metabolism, not gastric regulation. Acetylcholine's role in stimulating gastric secretions makes it the correct choice.
