NCLEX Questions on Gastrointestinal Disorders Questions
Question 1 of 5
Which of these does not belong with the others?
Correct Answer: A
Rationale: The correct answer is A: lipase. Lipase is an enzyme that breaks down lipids (fats), while the other enzymes listed (sucrase, maltase, lactase) are all involved in carbohydrate digestion. Lipase acts on a different substrate compared to the others, making it the odd one out in this group. Sucrase breaks down sucrose, maltase breaks down maltose, and lactase breaks down lactose. Therefore, A does not belong with the others as it does not share the same function of breaking down carbohydrates like the rest of the enzymes listed.
Question 2 of 5
A nurse is providing teaching about ileostomy care to a client. Which of the following statements by the client indicates a need for further teaching?

A: Correct, emptying pouch at 1/3 full is recommended. C: Correct, changing pouch weekly is important to prevent skin irritation. D: Correct, caution with high fiber foods to prevent blockages.
Question 3 of 5
A nurse is caring for a client who has a gastric ulcer. Which of the following herbal supplements should the nurse recommend?
Correct Answer: A
Rationale: The correct answer is A: Licorice. Licorice has been shown to have anti-inflammatory and mucosal protective effects on the gastrointestinal tract, which can benefit clients with gastric ulcers. It can help enhance mucous production and promote ulcer healing. Feverfew (B) may increase the risk of bleeding, Comfrey (C) contains pyrrolizidine alkaloids that can be toxic to the liver, and Ephedra (D) can worsen gastric ulcer symptoms due to its stimulant effect on the stomach.
Question 4 of 5
You're advising a 21 y.o. with a colostomy who reports problems with flatus. What food should you recommend?
Correct Answer: D
Rationale: The correct answer is D: Yogurt. Yogurt contains probiotics that promote healthy gut bacteria, aiding in digestion and reducing gas. It is easily digestible and less likely to cause excessive gas compared to choices A, B, and C, which are known to produce more gas due to their high fiber content. Peas, cabbage, and broccoli can exacerbate flatus issues in individuals with a colostomy, while yogurt can help alleviate them.
Question 5 of 5
Which of the following cranial nerves carries sensation from the digestive tract to the CNS?
Correct Answer: B
Rationale: The correct answer is B: vagus. The vagus nerve, or cranial nerve X, carries sensation from the digestive tract to the CNS. It is a major player in the parasympathetic nervous system, controlling many vital functions including digestion. The other options, gastric and spinal accessory, are not cranial nerves responsible for carrying sensations from the digestive tract. Choice D is incorrect as the vagus nerve specifically serves this function.
