Gastrointestinal NCLEX Questions and Answers Questions
Question 1 of 5
Which of the following is a function of bile?
Correct Answer: B
Rationale: The correct answer is B: digestion of fats. Bile is produced by the liver and stored in the gallbladder. It helps in emulsifying fats, breaking them down into smaller droplets to increase the surface area for enzymes to act upon. This aids in the digestion and absorption of fats in the small intestine. Other choices are incorrect because bile does not directly participate in the digestion of carbohydrates (A) or proteins (C). It also does not neutralize stomach acid (D), which is mainly done by pancreatic enzymes in the small intestine.
Question 2 of 5
A nurse is caring for a client who has a postoperative ileus and an NG tube that has drained 2,500 mL in the past 6 hr. Which of the following electrolyte imbalances should the nurse monitor the client for?
Correct Answer: B
Rationale: The correct answer is B: Decreased potassium level. Postoperative ileus can lead to fluid and electrolyte imbalances. When a client has been draining a large volume of gastric fluid through an NG tube, it can lead to potassium depletion. Potassium is a major intracellular electrolyte and plays a crucial role in muscle function, including smooth muscle in the intestines. The loss of potassium through excessive drainage can lead to hypokalemia, which can further impair bowel function and exacerbate the ileus. Monitoring potassium levels is essential to prevent complications. Choices A, C, and D are incorrect because elevated sodium, magnesium, and calcium levels are not typically associated with postoperative ileus and excessive NG tube drainage.
Question 3 of 5

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Which one of the following is absorbed in the GI tract without being digested?
Correct Answer: C
Rationale: The correct answer is C: vitamins. Vitamins are absorbed in the GI tract without being digested because they are already in a form that can be easily absorbed by the body. Unlike starch, proteins, and triglycerides which require digestion by enzymes to break them down into smaller molecules for absorption, vitamins are typically small molecules that can be directly absorbed into the bloodstream. Therefore, vitamins do not undergo digestion in the GI tract and are absorbed as they are. Starch, proteins, and triglycerides require digestion to be broken down into their respective components before they can be absorbed.
Question 5 of 5
The fauces refer to the
Correct Answer: A
Rationale: The correct answer is A: opening into the oropharynx. The fauces are the opening at the back of the mouth that leads into the oropharynx, connecting the mouth to the throat. This is where food and liquid pass through when swallowing. Choices B, C, and D are incorrect because the fauces specifically refer to the opening into the oropharynx, not the space between the cheek and gums, the cavity containing the tongue and teeth, or the opening into the larynx.
