NCLEX Questions on Gastrointestinal Disorders Questions
Question 1 of 5
The patient with suspected gallbladder disease is scheduled for an ultrasound of the gallbladder. What should the nurse explain to the patient about this test?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Which of the following membranes covers the stomach?
Correct Answer: D
Rationale: The correct answer is D: visceral peritoneum. The visceral peritoneum covers the stomach and is a serous membrane that covers the organs within the abdominal cavity. It provides support and protection to the stomach. The falciform ligament (choice A) attaches the liver to the anterior abdominal wall and doesn't cover the stomach. The mesocolon (choice B) is a peritoneal fold that supports the colon, not the stomach. The parietal peritoneum (choice C) lines the abdominal wall and does not cover the stomach directly. Therefore, the correct choice is D because the visceral peritoneum directly covers and protects the stomach.
Question 3 of 5
Which of the following statements about obesity in older adults is true?
Correct Answer: B
Rationale: The correct answer is B because obesity can indeed contribute to complications like osteoarthritis due to increased pressure on the joints. This is supported by research showing a link between obesity and joint issues. Choice A is incorrect as obesity can have various causes beyond excessive eating. Choice C is incorrect as metabolism can vary among older adults, and obesity remains a concern regardless. Choice D is incorrect as obesity tends to be a persistent issue that requires management rather than resolving with age.
Question 4 of 5
The nurse is caring for a patient who complains, "I don't see why I can't have a CT scan instead of the expensive MRI!" Which response is most appropriate for the nurse to make?
Correct Answer: A
Rationale: The correct answer is A because MRI provides better contrast between normal and pathologic tissue compared to CT scans. This is crucial for accurately diagnosing certain conditions. Choice B is incorrect as MRI images often require more complex analysis. Choice C is incorrect as both MRI and CT scans can produce digital images. Choice D is incorrect because CT scans expose patients to less radiation than MRI.
Question 5 of 5
Which of these is the site of most chemical digestion?
Correct Answer: B
Rationale: The correct answer is B: small intestine. The majority of chemical digestion occurs in the small intestine, specifically in the duodenum, where enzymes from the pancreas and bile from the liver break down food into nutrients. Stomach primarily performs mechanical digestion and initial protein breakdown. Mouth initiates mechanical digestion through chewing and begins carbohydrate digestion. Large intestine mainly absorbs water and electrolytes. Therefore, small intestine is the site of most chemical digestion due to its specialized enzymes and processes.
