NCLEX Questions Gastrointestinal System Questions
Question 1 of 5
The gastrointestinal tract (GI tract) includes all of the following, EXCEPT:
Correct Answer: B
Rationale: The correct answer is B: liver. The liver is not part of the gastrointestinal tract. The GI tract consists of the esophagus, stomach, and small intestine, where digestion and absorption of nutrients occur. The liver is an accessory organ that aids in digestion by producing bile but is not part of the tract itself. The liver is involved in detoxification, storage of nutrients, and production of important proteins, but it does not play a direct role in the digestion process. Therefore, the liver is the correct answer.
Question 2 of 5
Which action will the nurse include in the plan of care for a patient who is being admitted with Clostridium difficile?
Correct Answer: D
Rationale: The correct answer is D: Place the patient in a private room on contact isolation. This is important because Clostridium difficile is highly contagious, spread through contact with infected feces. Isolating the patient helps prevent the spread. A: Teaching about food storage is irrelevant to managing C. difficile. B: Administering medications is not mentioned in the question. C: Ordering a diet without dairy is not the priority; isolation is key to prevent transmission.
Question 3 of 5
A patient is receiving continuous enteral nutrition through a small-bore silicone feeding tube. What should the nurse plan for when this patient has a computed tomography (CT) scan ordered?
Correct Answer: B
Rationale: Rationale: - Correct Answer (B): Shutting off the feeding 30-60 mins before the CT scan reduces the risk of aspiration or vomiting during the procedure, minimizing potential complications. - Incorrect Answer (A): Rescheduling the scan is not necessary if feeding is temporarily stopped before the procedure. - Incorrect Answer (C): Connecting the feeding tube to continuous suction is unnecessary and may lead to dehydration or electrolyte imbalances. - Incorrect Answer (D): Sending a suction catheter with the patient is not a standard practice for CT scans; aspiration risk can be minimized by stopping the feeding temporarily.
Question 4 of 5
Which assessment action will help the nurse determine if an obese patient has metabolic syndrome?
Correct Answer: B
Rationale: The correct answer is B: Check the patient's blood pressure. Monitoring blood pressure is crucial in determining if an obese patient has metabolic syndrome, as high blood pressure is one of the key criteria for diagnosing metabolic syndrome. Elevated blood pressure is a common feature of metabolic syndrome and is linked to other risk factors such as obesity, insulin resistance, and dyslipidemia. By checking the patient's blood pressure, the nurse can assess if the patient meets the criteria for metabolic syndrome. Choice A (Take the patient's apical pulse) is not directly related to diagnosing metabolic syndrome. Choice C (Ask the patient about dietary intake) may provide important information but does not specifically help in diagnosing metabolic syndrome. Choice D (Dipstick the patient's urine for protein) is not a relevant assessment for determining metabolic syndrome.
Question 5 of 5
Which part of a tooth most closely resembles bone tissue?
Correct Answer: C
Rationale: The correct answer is C: dentin. Dentin is the part of the tooth that closely resembles bone tissue because it is a hard, dense tissue similar to bone in composition and structure, providing support and protection to the tooth. Dentin is located beneath the enamel and cementum, forming the bulk of the tooth structure. Enamel (choice A) is the hardest tissue in the body but is not similar to bone tissue in composition. Cementum (choice B) is a hard tissue covering the roots of teeth but is not as similar to bone tissue as dentin. Gingiva (choice D) is the soft tissue that surrounds the teeth and is not similar to bone tissue.
