Which organ produces bile?
- A. Pancreas
- B. Gallbladder
- C. Liver
- D. Stomach
Correct Answer: C
Rationale: The correct answer is C: Liver. The liver produces bile, which plays a crucial role in digestion by breaking down fats. The pancreas (A) produces digestive enzymes, not bile. The gallbladder (B) stores bile produced by the liver but does not produce it. The stomach (D) produces gastric juices, not bile. Therefore, the liver is the only organ that produces bile, making it the correct answer.

The enzymes present in pancreatic juice are
- A. Amylase, Trypsinogen, Peptidase, Rennin
- B. Trypsinogen, Lipase, Amylase, Procarbo xypeptidase
- C. Peptidase, Pepsin, Amylase, Rennin
- D. Maltase, Amylase, Trypsinogen, Pepsin
Correct Answer: B
Rationale: The correct answer is B because pancreatic juice contains enzymes such as Trypsinogen, Lipase, Amylase, and Procarboxypeptidase. Trypsinogen helps in protein digestion, Lipase breaks down fats, Amylase digests carbohydrates, and Procarboxypeptidase aids in protein digestion.
Choice A is incorrect because it includes Rennin, which is not typically found in pancreatic juice. Choice C is incorrect because Pepsin is a stomach enzyme, not found in pancreatic juice. Choice D is incorrect because Maltase is an enzyme found in the small intestine, not in pancreatic juice.
The gastrointestinal tract (GI tract) includes all of the following, EXCEPT:
- A. esophagus
- B. liver
- C. stomach
- D. small intestine
Correct Answer: B
Rationale: The correct answer is B: liver. The liver is not part of the gastrointestinal tract. The GI tract consists of the esophagus, stomach, and small intestine, where digestion and absorption of nutrients occur. The liver is an accessory organ that aids in digestion by producing bile but is not part of the tract itself. The liver is involved in detoxification, storage of nutrients, and production of important proteins, but it does not play a direct role in the digestion process. Therefore, the liver is the correct answer.
Which adult should the nurse plan to teach about risks associated with obesity?
- A. Man who has a BMI of 18 kg/m2
- B. Man with a 42 in waist and 44 in hips
- C. Woman who has a body mass index (BMI) of 24 kg/m2
- D. Woman with a waist circumference of 34 inches (86 cm)
Correct Answer: B
Rationale: The correct answer is B because a waist circumference of 42 inches in men signifies abdominal obesity, which is a significant risk factor for health issues related to obesity. A high waist circumference indicates excess visceral fat, which is linked to heart disease and other health problems.
Choice A is incorrect because a BMI of 18 kg/m2 indicates underweight, not obesity.
Choice C is incorrect because a BMI of 24 kg/m2 falls within the healthy weight range, not indicating obesity.
Choice D is incorrect because a waist circumference of 34 inches in women is considered normal, not indicative of obesity.
Bile is produced by which organ and stored in the gallbladder until needed for digestion?
- A. Stomach
- B. Liver
- C. Pancreas
- D. Small intestine
Correct Answer: B
Rationale: The correct answer is B: Liver. The liver produces bile, which is a greenish-yellow fluid that helps in the digestion and absorption of fats. It is stored in the gallbladder and released into the small intestine when needed. The stomach (A) produces gastric juices, not bile. The pancreas (C) produces digestive enzymes, but not bile. The small intestine (D) is where bile is released to aid in the digestion of fats, not where it is produced or stored.
A client has to undergo a barium enema for a suspected GI disorder. During the test, he experiences a strong urge to defecate and seeks the nurse's advice. Which of the following should the nurse do?
- A. Advise him to clear his bowel immediately
- B. Assure him that most people can retain the urge
- C. Give him analgesics to relieve him of the urge
- D. Instruct him to drink plenty of fluids
Correct Answer: B
Rationale: The correct answer is B: Assure him that most people can retain the urge. The rationale is as follows:
1. Retaining the urge during a barium enema is common due to the pressure from the barium solution.
2. Advising the client to clear his bowel immediately is incorrect because it may disrupt the test.
3. Giving analgesics to relieve the urge is incorrect as it does not address the issue.
4. Instructing to drink plenty of fluids is incorrect as it does not help in managing the urge.
In summary, choice B is correct as it reassures the client and helps maintain the integrity of the test.
