Gastrointestinal NCLEX Questions Questions
Question 1 of 5
The Kupffer cells are phagocytic cells found in the _____.
Correct Answer: D
Rationale: The correct answer is D: liver. Kupffer cells are specialized macrophages found in the liver, where they play a crucial role in phagocytosis and immune responses. They help remove debris, toxins, and pathogens from the blood. The other options (A: gallbladder, B: pancreas, C: intestine) are incorrect because Kupffer cells are not typically present in these organs. The liver is the main site for Kupffer cells due to its role in filtering and processing blood.
Question 2 of 5
Secretin and cholecystokinin are secreted in
Correct Answer: C
Rationale: The correct answer is C, duodenum. Secretin and cholecystokinin are hormones secreted by the duodenal mucosa in response to the presence of acidic chyme from the stomach entering the duodenum. Secretin stimulates the pancreas to release bicarbonate to neutralize the acidic chyme, while cholecystokinin stimulates the gallbladder to release bile to aid in digestion. Choices A (pyloric region), B (Ileum), and D (Oesophagus) are incorrect because secretin and cholecystokinin are not secreted in these regions of the gastrointestinal tract.
Question 3 of 5
A nurse is admitting a client who was prescribed antibiotic therapy and now has a Clostridium difficile infection. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: The correct answer is A: Disinfect equipment in the client's room daily. This is important for preventing the spread of Clostridium difficile, a highly contagious bacterium causing severe diarrhea. Disinfecting equipment helps eliminate the bacteria from the environment, reducing the risk of transmission to other individuals. Summary of other choices: B: Placing the client in a protective environment is unnecessary and not recommended for Clostridium difficile infection. C: While using alcohol hand sanitizer is important for hand hygiene, disinfecting equipment is more crucial in this case. D: Having the client wear a mask is not necessary for preventing the transmission of Clostridium difficile.
Question 4 of 5
A nurse is assessing a client who has an obstruction of the common bile duct resulting from chronic cholecystitis. Which of the following findings should the nurse expect?
Correct Answer: A
Rationale: The correct answer is A: Fatty stools. Common bile duct obstruction leads to inadequate bile flow into the intestines, resulting in malabsorption of fats. This causes fatty stools due to the presence of undigested fats. Straw-colored urine (B) is a normal finding. Tenderness in the left upper abdomen (C) is more indicative of splenic issues. Ecchymosis of the extremities (D) is unrelated to common bile duct obstruction.
Question 5 of 5
The muscular contractions, which move material through the digestive tract, are called:
Correct Answer: A
Rationale: The correct answer is A: peristalsis. Peristalsis refers to the wave-like muscular contractions that propel food through the digestive tract. First, circular muscles contract behind the food bolus creating a narrowing, then longitudinal muscles contract ahead of the bolus, pushing it forward. This coordinated movement helps move food along the digestive tract efficiently. Deglutition (B) refers to the act of swallowing, not the movement of food through the digestive tract. Mass movements (C) refer to large, powerful contractions that occur in the colon to move feces. Segmental contractions (D) are localized contractions that mix and churn food in the intestines, not the primary mechanism for moving food along the digestive tract.
