Gastrointestinal NCLEX Questions and Answers Questions
Question 1 of 5
Which statement about dietary fibre is most correct?
Correct Answer: C
Rationale: The correct answer is C because hemicelluloses, pectins, and inulin are indeed rapidly fermented to short-chain fatty acids in the colon, providing trophic effects. This is supported by scientific evidence. Choice A is incorrect because the main end products of fermentation of dietary fiber are short-chain fatty acids, not malic, succinic, and propionic acids. Choice B is incorrect as not all forms of fiber are completely fermented within 24 hours, and the time frame can vary. Choice D is incorrect because stool bulking is primarily attributed to soluble fibers, which hold water and increase stool bulk, rather than insoluble fibers like cellulose.
Question 2 of 5
In which exercise situation would you expect creatine supplementation to most likely improve performance?
Correct Answer: A
Rationale: Rationale: Creatine primarily benefits high-intensity, short-duration activities by aiding in quick energy production through ATP regeneration. All-out sprints fall under this category, making creatine supplementation effective. In contrast, choices B and C involve longer durations where creatine's benefits are less pronounced. Choice D is incorrect as creatine has been shown to enhance performance in specific exercise scenarios.
Question 3 of 5
You are preparing to administer TPN through a central line. Place the steps for administration in the correct order.
Correct Answer: C
Rationale: The correct order for administering TPN through a central line starts with checking the solution for cloudiness or turbidity to ensure it's safe for infusion. This step is crucial to prevent potential complications such as infection or embolism. Aseptic technique (Choice A) is important but comes later after verifying solution clarity. Threading the IV tubing (Choice B) and connecting it to the central line (Choice D) should follow after ensuring the solution is clear. These steps are all essential but must be done in the correct order to prioritize patient safety and prevent adverse effects.
Question 4 of 5
For which condition is magnetic resonance elastography showing great promise?
Correct Answer: D
Rationale: The correct answer is D, Cirrhosis of the liver. Magnetic resonance elastography (MRE) is a non-invasive imaging technique used to assess tissue stiffness, making it ideal for evaluating liver fibrosis in cirrhosis. MRE can accurately detect and quantify liver stiffness, providing valuable information about the progression of cirrhosis and guiding treatment decisions. Choice A, Gallstones, is incorrect as MRE is not typically used to diagnose this condition. Choice B, Pancreatic cancer, is also incorrect as MRE is not the primary imaging modality for this cancer. Choice C, Cholecystitis, is incorrect because MRE is not commonly used to diagnose inflammation of the gallbladder. In summary, MRE is particularly useful in assessing liver fibrosis in cirrhosis due to its ability to measure tissue stiffness accurately.
Question 5 of 5
Which of the following should a nurse instruct a client with symptomatic gallstones to avoid?
Correct Answer: A
Rationale: Rationale: Symptomatic gallstones can be aggravated by caffeine, which stimulates gallbladder contractions, leading to pain. Avoiding coffee and caffeine-containing products helps reduce symptoms. Summary: - B: Fruits and fruit juices are generally healthy and do not directly impact gallstones. - C: Milk and milk products do not have a direct effect on gallstones. - D: Potassium-rich foods are beneficial for overall health and not specifically contraindicated for gallstones.
