The accessory digestive organs include all of the following, EXCEPT:
- A. tongue
- B. liver
- C. pancreas
- D. stomach
Correct Answer: D
Rationale: The correct answer is D, stomach. The stomach is not considered an accessory digestive organ as it is part of the gastrointestinal tract. The accessory digestive organs aid in the digestion process but are not part of the tract itself. The tongue, liver, and pancreas are all considered accessory digestive organs as they play crucial roles in digestion, such as producing enzymes and bile. The stomach's main function is to store and break down food through mechanical and chemical digestion, making it a primary organ in the digestive system rather than an accessory one.

A client with an ileostomy wants to know why to avoid fibrous vegetables. What should be the nurse's response?
- A. They cause gas formation.
- B. They cause stomal obstruction.
- C. They are difficult to digest.
- D. They increase the risk of diarrhea.
Correct Answer: B
Rationale: The correct answer is B because fibrous vegetables can potentially cause stomal obstruction in clients with an ileostomy due to their indigestible nature, leading to blockages in the stoma. This can result in severe complications and require medical intervention. Gas formation (choice A) is a common issue with high-fiber foods but is not specific to fibrous vegetables. Fibrous vegetables are not necessarily difficult to digest (choice C) for most individuals, although they may be harder for those with reduced gut function. While fibrous vegetables may contribute to loose stools, they do not directly increase the risk of diarrhea (choice D) in the same way they can cause stomal obstruction.
A hiatal hernia is a weakness in the _____ muscle, which allows a portion of the digestive tract to enter the thoracic cavity.
- A. diaphragm
- B. stomach
- C. intestinal
- D. thoracic wall
Correct Answer: A
Rationale: The correct answer is A: diaphragm. The diaphragm is a dome-shaped muscle that separates the thoracic and abdominal cavities. A hiatal hernia occurs when the stomach pushes through the opening in the diaphragm known as the esophageal hiatus, allowing a portion of the stomach to enter the thoracic cavity. The other choices, B: stomach, C: intestinal, and D: thoracic wall, are incorrect because a hiatal hernia specifically involves a weakness in the diaphragm muscle, not in these other structures. The stomach is the organ affected by the hernia, but the primary issue lies in the diaphragm's weakness. The intestinal and thoracic wall choices are not directly related to the development of a hiatal hernia.
This region of the large intestine has a simple columnar epithelium in its tunica mucosa, smooth muscle in its tunica muscularis, and epiploic appendages attach to its outer surface. This region is called the
- A. cecum.
- B. colon.
- C. rectum.
- D. anal canal.
Correct Answer: B
Rationale: The correct answer is B: colon. The colon is characterized by having a simple columnar epithelium in its tunica mucosa, smooth muscle in its tunica muscularis, and epiploic appendages attached to its outer surface. The cecum (A) is a pouch-like structure at the beginning of the large intestine. The rectum (C) is the final segment of the large intestine before the anal canal (D). The anal canal is lined by stratified squamous epithelium, not simple columnar epithelium like the colon.
Which esophageal disorder is described as a precancerous lesion associated with GERD?
- A. Achalasia
- B. Barrett's esophagus
- C. Esophageal strictures
- D. Esophageal diverticula
Correct Answer: B
Rationale: Barrett's esophagus is the correct answer because it is a precancerous condition resulting from long-term GERD. The constant exposure to stomach acid causes changes in the esophageal lining, increasing the risk of esophageal cancer.
Achalasia (A) is a motility disorder characterized by difficulty swallowing due to impaired esophageal muscle movement. Esophageal strictures (C) are narrowing of the esophagus, commonly caused by chronic inflammation or scarring, but not directly associated with GERD. Esophageal diverticula (D) are outpouchings in the esophageal wall, not specifically linked to GERD or cancer risk.
Using MyPlate as a guide, what changes could the nurse suggest to bring the man's diet more in line with nutrition recommendations?
- A. Increase fruits and vegetables
- B. Decrease protein intake
- C. Increase fat intake
- D. Increase calorie intake
Correct Answer: A
Rationale: The correct answer is A: Increase fruits and vegetables. MyPlate recommends filling half of your plate with fruits and vegetables. By suggesting this change, the nurse can help the man consume more essential nutrients, fiber, and antioxidants. This will improve his overall diet quality. Decreasing protein intake (B) may lead to inadequate protein consumption, which is essential for muscle health. Increasing fat intake (C) may lead to excess calorie intake and weight gain. Increasing calorie intake (D) may not be necessary and could lead to weight gain if not balanced with physical activity.
