NCLEX Questions on Gastrointestinal System Questions
Question 1 of 5
The falciform ligament separates the right from _____ lobe.
Correct Answer: B
Rationale: The falciform ligament separates the right and left lobes of the liver. This is because it attaches the liver to the anterior abdominal wall and suspends it from the diaphragm, dividing the liver into right and left lobes. The quadrate, caudate, and pancreatic lobes are not separated by the falciform ligament, making choices A, C, and D incorrect, respectively.
Question 2 of 5
Carboxypeptidase requires _______ for its activity
Correct Answer: D
Rationale: Carboxypeptidase is a metalloenzyme that requires zinc (Zn) for its activity as a cofactor. Zinc plays a crucial role in stabilizing the enzyme's structure and facilitating the catalytic reaction. Copper (A), niacin (B), and iron (C) are not directly involved in the enzymatic activity of carboxypeptidase. Copper is more commonly associated with other enzymes like cytochrome c oxidase, niacin is a vitamin, and iron is typically involved in heme-containing proteins like hemoglobin. Zinc is the correct choice as it directly supports carboxypeptidase function.
Question 3 of 5
A nurse is reviewing the provider's prescriptions for a client experiencing a paralytic ileus following an appendectomy. Which of the following actions should the nurse expect to take?
Correct Answer: C
Rationale: The correct answer is C: Insert nasogastric tube. In a paralytic ileus, the intestines are unable to contract and move contents, leading to bowel obstruction. Inserting a nasogastric tube helps decompress the intestines by removing gas and fluid, relieving discomfort and preventing further complications. Administering an antacid (A) is not indicated for paralytic ileus. Providing a bulk-forming agent (B) may exacerbate the obstruction. Applying a truss (D) is used for hernias, not for paralytic ileus.
Question 4 of 5
A nurse is caring for a client who requires total parenteral nutrition (TPN). Which of the following actions should the nurse take when finding that the TPN solution is infusing too rapidly?
Correct Answer: D
Rationale: The correct answer is D: Stop the TPN infusion. If the TPN solution is infusing too rapidly, stopping the infusion is the most appropriate immediate action to prevent potential complications such as hyperglycemia, fluid overload, or electrolyte imbalances. This allows the nurse to assess the situation, adjust the infusion rate, and prevent harm to the client. A: Turning the client on his left side or sitting the client upright would not directly address the issue of the TPN solution infusing too rapidly. C: Adding insulin to the TPN infusion without assessing the client's blood glucose levels and consulting with the healthcare provider could lead to hypoglycemia and is not the initial priority when the TPN rate is too fast.
Question 5 of 5
Nurse Hannah is teaching a group of middle-aged men about peptic ulcers. When discussing risk factors for peptic ulcers, the nurse should mention:
Correct Answer: D
Rationale: The correct answer is D: Alcohol abuse and smoking. Both alcohol abuse and smoking are well-established risk factors for peptic ulcers. Alcohol can irritate and damage the stomach lining, while smoking can increase stomach acid production and weaken the stomach lining. These factors can contribute to the development of peptic ulcers. Choice A (A sedentary lifestyle and smoking) is incorrect because while smoking is a risk factor, a sedentary lifestyle is not directly linked to the development of peptic ulcers. Choice B (A history of hemorrhoids and smoking) is incorrect because hemorrhoids are not a known risk factor for peptic ulcers. Choice C (Alcohol abuse and a history of acute renal failure) is incorrect because acute renal failure is not typically associated with an increased risk of peptic ulcers, unlike alcohol abuse.
