Gastrointestinal Diseases NCLEX Review Questions Questions
Question 1 of 5
What causes the systemic effects of viral hepatitis?
Correct Answer: D
Rationale: Step-by-step rationale for why choice D is correct: Activation of the complement system by antigen-antibody complexes leads to systemic effects in viral hepatitis. This process triggers inflammation, tissue damage, and immune responses that contribute to the systemic effects seen in viral hepatitis. The other choices (A, B, and C) do not directly cause systemic effects in viral hepatitis. Cholestasis and impaired portal circulation are more localized effects, while toxins produced by the infected liver may contribute to liver damage but not necessarily systemic effects.
Question 2 of 5
What is the priority action when caring for a patient with acute cholecystitis and suspected perforation?
Correct Answer: A
Rationale: The correct answer is A: Prepare for surgery immediately. This is the priority action because acute cholecystitis with suspected perforation is a surgical emergency that requires prompt intervention to prevent serious complications such as sepsis. Surgery is needed to remove the inflamed gallbladder and repair any perforation. Administering IV fluids, pain medication, and antibiotics are important supportive measures but do not address the underlying issue. Monitoring vital signs is also crucial, but immediate surgical intervention takes precedence in this critical situation.
Question 3 of 5
The nurse is caring for a patient who returns to the floor at lunchtime after undergoing an upper GI (UGI) series. Which action is most important for the nurse to perform first?
Correct Answer: A
Rationale: The correct answer is A: Administer a laxative. After an upper GI series, it is important to help the patient eliminate the contrast dye used during the procedure. Administering a laxative will facilitate the removal of the dye from the gastrointestinal tract. This is crucial to prevent any potential complications or adverse effects from the contrast dye. Explanation for incorrect choices: B: Educating the patient about the possibility of white stools is not the most immediate concern after an upper GI series. While this information is important for the patient to know, it is not the most urgent action to take. C: Offering the patient a small snack may be appropriate after the procedure, but ensuring the elimination of the contrast dye through a laxative is more critical. D: Providing oral care is important for overall patient comfort and hygiene, but it is not the priority immediately following an upper GI series.
Question 4 of 5
Which phase of deglutition involves contraction of the longitudinal muscle layer of the muscularis?
Correct Answer: D
Rationale: The correct answer is D: esophageal phase. During the esophageal phase of deglutition, the longitudinal muscle layer of the muscularis contracts to help propel the bolus of food downwards towards the stomach. This contraction occurs in a coordinated manner to create peristaltic waves that push the food along the esophagus. In contrast, the voluntary phase (A) involves the conscious initiation of swallowing, the buccal phase (B) involves the tongue pushing the bolus towards the pharynx, and the pharyngeal phase (C) involves the initiation of the swallowing reflex and closure of the airway to prevent aspiration.
Question 5 of 5
The nurse is educating a patient who is starting treatment with warfarin. Which instruction is most important to include in the teaching plan?
Correct Answer: B
Rationale: The correct answer is B: "Be sure to have regular blood tests to monitor your INR." Warfarin is a medication that requires close monitoring of the International Normalized Ratio (INR) to ensure it is within the therapeutic range. Regular blood tests are crucial to prevent complications such as bleeding or blood clots. Choice A is incorrect because aspirin increases the risk of bleeding when taken with warfarin. Choice C is incorrect because increasing vitamin K-rich foods can interfere with the effectiveness of warfarin. Choice D is incorrect because doubling the dose can lead to an increased risk of bleeding. Regular monitoring of INR levels is essential for safe and effective warfarin therapy.
