Multiple Choice Questions on Gastrointestinal Disorders Quizlet Questions
Question 1 of 5
Ferritin is a globular protein that transports and stores ______ in the liver and blood.
Correct Answer: D
Rationale: The correct answer is D: iron. Ferritin is a protein that binds and stores iron in the liver and blood. It plays a crucial role in regulating iron levels in the body. Glycogen (A) is a storage form of glucose, not stored by ferritin. Lipids (B) are not stored by ferritin either. Vitamin B12 (C) is mainly stored in the liver bound to specific proteins, not ferritin. Iron is the correct answer as it aligns with the main function of ferritin in iron transport and storage.
Question 2 of 5
Which of the following enzymes is involved in the breakdown of proteins?
Correct Answer: C
Rationale: The correct answer is C: pepsin. Pepsin is an enzyme produced in the stomach that helps break down proteins into peptides. It works in a highly acidic environment, denaturing proteins. Amylase (A) breaks down carbohydrates, lipase (B) breaks down fats, and maltase (D) breaks down maltose into glucose. Pepsin is specifically designed to target proteins, making it the correct choice.
Question 3 of 5
A nurse is caring for a client who has peptic ulcer disease. The nurse should monitor the client for which of the following findings as an indication of gastrointestinal perforation?
Correct Answer: B
Rationale: The correct answer is B: Sudden abdominal pain. Gastrointestinal perforation is a serious complication of peptic ulcer disease. Sudden abdominal pain is a key indicator as perforation can lead to leakage of stomach contents into the abdominal cavity causing severe pain. Hyperactive bowel sounds (A) are more indicative of bowel obstruction. Increased blood pressure (C) can occur due to pain or stress but is not specific to gastrointestinal perforation. Bradycardia (D) is not typically associated with gastrointestinal perforation.
Question 4 of 5
A nurse is caring for a client who has an active upper gastrointestinal bleed. After inserting a NG tube into the client, which of the following findings should the nurse anticipate?
Correct Answer: C
Rationale: The correct answer is C: Coffee-ground drainage. This indicates upper GI bleed, where blood mixes with gastric acid, forming a coffee-ground appearance. Frothy pink drainage (A) is more common in respiratory issues. Dark amber drainage (B) is typical for lower GI bleeds. Greenish-yellow drainage (D) is not associated with GI bleeding. In this case, the nurse should monitor for coffee-ground drainage to assess the severity of the upper GI bleed.
Question 5 of 5
Donald is a 61 y.o. man with diverticulitis. Diverticulitis is characterized by:
Correct Answer: D
Rationale: The correct answer is D because diverticulitis typically presents with crampy pain in the lower left quadrant of the abdomen and a low-grade fever. This is due to inflammation or infection of the diverticula. A: Periodic rectal hemorrhage is more characteristic of diverticular bleeding, not diverticulitis. B: Hypertension and tachycardia are not typically associated with diverticulitis but may occur in severe cases or with complications. C: Vomiting and elevated temperature can occur but are not as specific to diverticulitis as the combination of symptoms described in option D.
