The secretion of the exocrine pancreas is increased by the following except:
- A. Vagal stimulation
- B. Acetylcholine
- C. Secretin
- D. CCK
Correct Answer: A
Rationale: The correct answer is A: Vagal stimulation. Vagal stimulation does not directly increase the secretion of the exocrine pancreas. Acetylcholine, Secretin, and CCK are known to stimulate pancreatic secretion through various mechanisms. Acetylcholine acts through muscarinic receptors, Secretin is released in response to acidic chyme in the duodenum, and CCK is released in response to fat and proteins in the duodenum, all leading to increased pancreatic enzyme secretion. Vagal stimulation plays a role in the parasympathetic nervous system but does not directly stimulate pancreatic secretion.

Which of the following is not a part of the digestive system?
- A. Liver
- B. Gallbladder
- C. absorption-neet-mcq/ 8/13 1/17/25, 2:54 PM Digestion and Absorption NEET MCQ 2024
- D. Lungs
Correct Answer: D
Rationale: The correct answer is D: Lungs. The lungs are not a part of the digestive system. The digestive system is responsible for breaking down food into nutrients, absorbing those nutrients, and eliminating waste. The lungs are part of the respiratory system, responsible for gas exchange. Liver (A) and gallbladder (B) are both part of the digestive system, aiding in digestion and nutrient absorption. Absorption (C) is a process within the digestive system, not a separate entity. In summary, the lungs do not play a role in the digestion process, making them the correct answer choice.
Occult fecal blood test would be helpful in discovering:
- A. colonic carcinoma
- B. malabsorption syndrome
- C. both
- D. neither
Correct Answer: A
Rationale: The occult fecal blood test detects hidden blood in the stool, which can be an early sign of colonic carcinoma. This test is not specific for malabsorption syndrome, making option B incorrect. Option C is incorrect because the test is primarily used for detecting colonic carcinoma. Option D is incorrect as the test can aid in the discovery of colonic carcinoma.
A nurse is caring for a client who has an active upper gastrointestinal bleed. After inserting a NG tube into the client, which of the following findings should the nurse anticipate?
- A. Frothy pink drainage
- B. Dark amber drainage
- C. Coffee-ground drainage
- D. Greenish-yellow drainage
Correct Answer: C
Rationale: The correct answer is C: Coffee-ground drainage. This indicates upper GI bleed, where blood mixes with gastric acid, forming a coffee-ground appearance. Frothy pink drainage (A) is more common in respiratory issues. Dark amber drainage (B) is typical for lower GI bleeds. Greenish-yellow drainage (D) is not associated with GI bleeding. In this case, the nurse should monitor for coffee-ground drainage to assess the severity of the upper GI bleed.
