Gastrointestinal Nursing Questions Questions
Question 1 of 5
Which of the following characterizes the biologic nature of carcinoid tumors (argentaffinomas)?
Correct Answer: B
Rationale: Step-by-step rationale for why choice B is correct: 1. Carcinoid tumors can produce systemic symptoms due to the release of bioactive substances. 2. Metastasis to the liver can lead to the production of systemic symptoms like flushing and diarrhea. 3. This systemic symptom production is a characteristic feature of carcinoid tumors. 4. Choice B accurately describes the biologic nature of carcinoid tumors in relation to systemic symptoms. Summary of why other choices are incorrect: A: Carcinoid tumors can be malignant and produce systemic symptoms, so they are not always benign. C: Carcinoid tumors originating in the appendix are typically associated with a more favorable prognosis. D: Jejunal ulceration due to gastrin elaboration is more commonly seen in gastrinomas, not carcinoid tumors.
Question 2 of 5
Cimetidine and a calcium-containing antacid preparation administered in an appropriate dosage regimen for treating peptic ulcer differ in that:
Correct Answer: A
Rationale: The correct answer is A because only the calcium-containing antacid may increase gastric acid secretion. This is because calcium-containing antacids can stimulate the release of gastrin, which in turn increases gastric acid secretion. Choices B, C, and D are incorrect because cimetidine, not a calcium-containing antacid, is the one that can cause an increase in urinary pH, produce a laxative effect, and prevent the rise in gastric pH after a meal, respectively. Therefore, A is the only statement that accurately distinguishes between cimetidine and a calcium-containing antacid in the context of treating peptic ulcers.
Question 3 of 5
Which of the following is not a part of the small intestine?
Correct Answer: D
Rationale: The correct answer is D: Colon. The colon is not a part of the small intestine; it is part of the large intestine. The small intestine consists of three parts: the duodenum, jejunum, and ileum. The duodenum is the first segment of the small intestine, followed by the jejunum and then the ileum. The colon, also known as the large intestine, comes after the small intestine in the digestive system. Therefore, the colon is not a part of the small intestine, making choice D the correct answer.
Question 4 of 5
What condition should the nurse anticipate when caring for a patient with a history of a total gastrectomy?
Correct Answer: D
Rationale: The correct answer is D: Cobalamin (vitamin B12) deficiency. After a total gastrectomy, the patient lacks the intrinsic factor needed for vitamin B12 absorption in the ileum, leading to deficiency. This can result in megaloblastic anemia, neurological symptoms, and fatigue. A: Constipation is not typically associated with total gastrectomy. B: Dehydration may occur postoperatively but is not a specific consequence of total gastrectomy. C: Elevated total serum cholesterol is not a direct effect of total gastrectomy.
Question 5 of 5
A 25-yr-old male patient calls the clinic reporting diarrhea for 24 hours. Which action should the nurse take first?
Correct Answer: D
Rationale: The correct answer is D because asking the patient to describe the stools and associated symptoms helps the nurse gather important information for assessment. Understanding the frequency, consistency, color, and presence of blood in the stools can help determine the severity and potential causes of diarrhea. This information guides the nurse in deciding the appropriate next steps for care. Option A is incorrect as testing should be based on assessment findings. Option C is premature without assessing the patient first. Option B lacks relevance to the assessment process.
