Gastrointestinal Questions and Answers Questions
Question 1 of 5
Which of the following hormones stimulates the release of bile from the gallbladder?
Correct Answer: C
Rationale: Cholecystokinin (CCK) is the correct answer as it specifically stimulates the release of bile from the gallbladder. It is released in response to the presence of fats and proteins in the duodenum, signaling the gallbladder to contract and release bile to aid in digestion. Insulin is involved in regulating blood sugar levels, while gastrin stimulates gastric acid secretion. Secretin stimulates the release of bicarbonate-rich pancreatic juice to neutralize stomach acid, not bile secretion. Therefore, CCK is the most appropriate choice in this context.
Question 2 of 5
A nurse is reviewing the medical record of a client who has a peptic ulcer. Which of the following findings should the nurse recognize as a risk factor for this condition?
Correct Answer: B
Rationale: The correct answer is B: History of NSAID use. NSAIDs (nonsteroidal anti-inflammatory drugs) such as aspirin and ibuprofen can irritate the stomach lining and increase the risk of developing peptic ulcers. Bulimia (choice A) can lead to other gastrointestinal issues but is not a direct risk factor for peptic ulcers. Drinking green tea (choice C) is actually associated with potential protective effects against peptic ulcers due to its antioxidant properties. Having a glass of wine daily (choice D) is not a known risk factor for peptic ulcers.
Question 3 of 5
Patients with esophageal varices would reveal the following assessment:
Correct Answer: B
Rationale: The correct answer is B: Increased heart rate. Esophageal varices are dilated blood vessels in the esophagus, commonly associated with liver cirrhosis. Due to increased pressure in the portal vein system, patients with esophageal varices may experience increased heart rate as a compensatory mechanism to maintain cardiac output. The other choices are incorrect because esophageal varices are not typically associated with increased blood pressure (A), decreased respiratory rate (C), or increased urinary output (D).
Question 4 of 5
The lamina propria and muscularis mucosa are found in the tunica
Correct Answer: A
Rationale: The lamina propria and muscularis mucosa are components of the mucosa layer. The lamina propria is a layer of connective tissue beneath the epithelium, while the muscularis mucosa is a thin layer of smooth muscle. Both are part of the mucosa, which is the innermost layer of the gastrointestinal tract. Therefore, the correct answer is A: mucosa. The other choices are incorrect because the submucosa (B) is located outside the mucosa layer, the muscularis (C) is a separate layer of smooth muscle outside the mucosa, and the serosa (D) is the outermost layer of the gastrointestinal tract.
Question 5 of 5
Which one of the following is most easily absorbed in the oral cavity?
Correct Answer: B
Rationale: The correct answer is B: water. Water is the most easily absorbed in the oral cavity due to its small molecular size and simple structure, allowing for rapid absorption through the mucous membranes in the mouth. Glucose, fatty acids, and peptides are larger molecules that require further breakdown by enzymes in the digestive system before absorption can occur, making them less easily absorbed in the oral cavity. Water, being a small molecule and essential for various physiological functions, can be quickly absorbed directly through the oral mucosa into the bloodstream, providing immediate hydration and other benefits.
