Gastrointestinal NCLEX Questions and Answers Questions
Question 1 of 5
What is the term for the semi-solid mixture of food and digestive juices that are formed in the stomach?
Correct Answer: A
Rationale: The correct answer is A: Chyme. This term refers to the semi-solid mixture of food and digestive juices that is formed in the stomach through the process of digestion. The stomach mixes food with gastric juices to create chyme, which is then passed to the small intestine for further digestion and absorption of nutrients. B: Bolus is incorrect as it refers to the compact mass of food that is swallowed and travels through the esophagus to reach the stomach. C: Feces is incorrect as it is the solid waste material that is formed in the large intestine and expelled from the body. D: None of the above is incorrect as the term "chyme" accurately describes the semi-solid mixture formed in the stomach during digestion.
Question 2 of 5
Which question from the nurse would help determine if a patient's abdominal pain might indicate irritable bowel syndrome (IBS)?
Correct Answer: B
Rationale: The correct answer is B. Asking about foods affecting bowel patterns helps determine if the patient's abdominal pain could indicate IBS as certain foods can trigger IBS symptoms. Passing gas (A) is common in IBS but not specific enough. Abdominal distention (C) is a possible symptom but not exclusive to IBS. Knowing the duration of the pain (D) is important but does not directly link to IBS. Thus, B is the best choice to assess IBS related symptoms.
Question 3 of 5
Which intestinal layer accounts for the action of the peristaltic waves?
Correct Answer: B
Rationale: The correct answer is B: muscularis. The muscularis layer of the intestine is responsible for generating peristaltic waves through rhythmic contractions of smooth muscle, aiding in the movement of food along the digestive tract. The serosa (A) is the outermost layer that provides protection and support. The submucosa (C) contains blood vessels and nerves, while the mucous (D) layer secretes mucus for lubrication and protection. Therefore, the muscularis layer is specifically designed for peristalsis, making it the correct choice.
Question 4 of 5
What blocks pancreatic secretions from entering the duodenum?
Correct Answer: B
Rationale: The correct answer is B: sphincter of Oddi. This sphincter controls the flow of pancreatic secretions and bile into the duodenum. It regulates the release of digestive enzymes from the pancreas and bile from the liver, ensuring proper digestion. The other choices are incorrect because: A: pyloric valve controls the flow of food from the stomach to the small intestine, not pancreatic secretions. C: the common bile duct carries bile from the liver and gallbladder to the duodenum, not pancreatic secretions. D: cholecystokinin secretion is a hormone that stimulates the release of bile from the gallbladder, not a physical barrier to block pancreatic secretions.
Question 5 of 5
The ampulla of Vater is the area that joins the common bile duct to the _____ duct.
Correct Answer: B
Rationale: The correct answer is B: pancreatic. The ampulla of Vater is where the common bile duct and the pancreatic duct join before emptying into the duodenum. The pancreatic duct carries digestive enzymes from the pancreas, which mix with bile from the common bile duct to aid in digestion. Choices A, C, and D are incorrect because the hepatic duct carries bile from the liver to the common bile duct, the cystic duct connects the gallbladder to the common bile duct, and the common hepatic duct is a part of the biliary system but does not directly join to the ampulla of Vater.
