Gastrointestinal NCLEX Questions Questions
Question 1 of 5
The patient with liver failure has had a liver transplant. What should the nurse teach the patient about care after the transplant?
Correct Answer: D
Rationale: The correct answer is D because patients who undergo liver transplant are put on immunosuppressive medication to prevent rejection. This medication weakens the immune system, making the patient more susceptible to infections. Monitoring closely for signs of infection is crucial to prevent complications. Choice A is incorrect because alcohol intake is not recommended after a liver transplant as it can further damage the new liver. Choice B is incorrect because HBIG (Hepatitis B Immunoglobulin) is typically given to prevent hepatitis B recurrence, not rejection. Choice C is incorrect as elevating the head has no direct correlation with post-liver transplant care.
Question 2 of 5
The nurse is caring for a patient who complains, "I don't see why I can't have a CT scan instead of the expensive MRI!" Which response is most appropriate for the nurse to make?
Correct Answer: A
Rationale: The correct answer is A because MRI provides better contrast between normal and pathologic tissue compared to CT scans. This allows for more accurate diagnosis and treatment planning. Choice B is incorrect because MRI images are typically more complex and require specialized analysis. Choice C is incorrect because both CT and MRI images can be transmitted digitally. Choice D is incorrect because CT scans actually expose patients to less radiation compared to MRI.
Question 3 of 5
Which of these ingredients in saliva is responsible for activating salivary amylase?
Correct Answer: B
Rationale: The correct answer is B: phosphate ions. Phosphate ions present in saliva help activate salivary amylase by providing the necessary environment for the enzyme to function optimally. Salivary amylase works best at a slightly alkaline pH, which is facilitated by the presence of phosphate ions. Mucus (choice A) primarily helps with lubrication and binding of food particles but does not activate enzymes. Chloride ions (choice C) are not directly involved in activating salivary amylase. Urea (choice D) is a waste product and not related to enzyme activation in saliva. In summary, the correct answer is B because phosphate ions create the optimal pH environment for salivary amylase activity, while the other choices are not directly involved in enzyme activation.
Question 4 of 5
The nurse is caring for a patient who has been prescribed digoxin. Which statement by the patient indicates the need for further teaching about the medication?
Correct Answer: C
Rationale: The correct answer is C. This statement indicates a need for further teaching because stopping digoxin abruptly can be dangerous. Digoxin should not be discontinued without consulting a healthcare provider. A: Monitoring pulse rate is important as digoxin can affect heart rate. B: Consistency in timing helps maintain consistent drug levels. D: Monitoring weight is crucial as digoxin can cause fluid retention. Therefore, choice C is incorrect as it suggests a potentially harmful action.
Question 5 of 5
Where are most digestive enzymes secreted?
Correct Answer: C
Rationale: The correct answer is C: pancreas. The pancreas secretes most digestive enzymes, including amylase, lipase, and proteases, into the small intestine to aid in the digestion of carbohydrates, fats, and proteins. It plays a crucial role in breaking down food components. The stomach (choice A) secretes gastric juices but not the majority of digestive enzymes. The liver (choice B) produces bile, which aids in fat digestion, but does not secrete digestive enzymes. The small intestine (choice D) is where most digestion and absorption occur, but it does not secrete the majority of digestive enzymes.
