CCK:
- A. increases gastric secretion.
- B. inhibits the stomach motility.
- C. inhibits pancreatic enzyme secretion.
- D. increases pancreatic secretions rich in bicarbonate.
Correct Answer: B
Rationale: Step 1: CCK (Cholecystokinin) is released in response to the presence of fats and proteins in the small intestine.
Step 2: CCK inhibits stomach motility to allow enough time for the gallbladder to release bile.
Step 3: This slowing down of stomach motility aids in the digestion and absorption of fats.
Step 4: Choices A, C, and D are incorrect as CCK does not directly affect gastric secretion, pancreatic enzyme secretion, or increase pancreatic secretions rich in bicarbonate.

The painful or burning sensation in the chest usually associated with acid reflux in the esophagus is called
- A. a peptic ulcer.
- B. heart burn.
- C. angina.
- D. a duodenal ulcer.
Correct Answer: B
Rationale: The correct answer is B: heartburn. This is because heartburn is the common term for the painful or burning sensation in the chest caused by acid reflux in the esophagus. A peptic ulcer (A) and a duodenal ulcer (D) are sores in the stomach or small intestine, not specific to the chest area. Angina (C) is chest pain related to heart issues, not specifically caused by acid reflux. Therefore, B is the correct answer.
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?
- A. Fatty stools
- B. Straw-colored urine
- C. Tenderness in the left upper abdomen
- D. Ecchymosis of the extremities
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.
A nurse enters the room of a client with cramping, bloating, and flatus, as well as diarrhea and/or constipation, with or without the presence of mucus. What condition do the client's symptoms represent?
- A. Peritonitis
- B. Irritable bowel syndrome
- C. Ulcerative colitis
- D. Appendicitis
Correct Answer: B
Rationale: The correct answer is B: Irritable bowel syndrome. The symptoms described align with the criteria for diagnosing IBS, such as cramping, bloating, and changes in bowel habits. Peritonitis (A) is characterized by severe abdominal pain, fever, and rigidity. Ulcerative colitis (C) presents with bloody diarrhea and abdominal pain. Appendicitis (D) typically causes localized right lower quadrant pain, nausea, and vomiting. Therefore, based on the given symptoms, IBS is the most likely diagnosis.
The Kupffer cells are phagocytic cells found in the _____.
- A. gallbladder
- B. pancreas
- C. intestine
- D. liver
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.
The function of the gastrointestinal tract can be classified in several ways. Which of the following functions is most important for survival immediately after a meal?
- A. Absorption and retention of water and electrolytes
- B. Elimination of toxins
- C. Maintenance of barrier function
- D. Extraction of maximum value from nutrients
Correct Answer: A
Rationale: The correct answer is A: Absorption and retention of water and electrolytes. Immediately after a meal, the body needs to absorb water and electrolytes to maintain proper hydration and electrolyte balance, crucial for survival. This process helps in nutrient absorption and maintaining overall body function.
Reasons for why the other choices are incorrect:
B: Elimination of toxins - While important for overall health, elimination of toxins is not the most critical function immediately after a meal for survival.
C: Maintenance of barrier function - While important for protecting against harmful substances, it is not the most vital function immediately after a meal for survival.
D: Extraction of maximum value from nutrients - While important for optimal nutrition, it is not as crucial as absorption and retention of water and electrolytes for immediate survival post-meal.
