1. Which of the following conditions can cause a hiatal hernia?
- A. Increased intrathoracic pressure
- B. Weakness of the esophageal muscle
- C. Increased esophageal muscle pressure
- D. Weakness of the diaphragmic muscle
Correct answer: D
Rationale: Weakness of the diaphragmic muscle can lead to a hiatal hernia as it allows part of the stomach to push through the diaphragm into the chest cavity.
2. A nurse is caring for a client diagnose with pancreatitis. The nurse anticipates that the client would not experience an elevation of which of the following enzymes?
- A. Lipase
- B. Lactase
- C. Amylase
- D. Trypsin
Correct answer: B
Rationale: Lactase is produced in the small intestine and aids in splitting neutral fats into glycerol and fatty acids. Lipase, amylase, and trypsin are produced in the pancreas and aid in the digestion of fats, starches, and proteins, respectively.
3. A client has a nasogastric tube inserted at the time of abdominal perineal resection with permanent colostomy. This tube will most likely be removed when the client demonstrates:
- A. Absence of nausea and vomiting.
- B. Passage of mucus from the rectum.
- C. Passage of flatus and feces from the colostomy.
- D. Absence of stomach drainage for 24 hours.
Correct answer: C
Rationale: A sign indicating that a client's colostomy is open and ready to function is passage of feces and flatus. When this occurs, gastric suction is ordinarily discontinued, and the client is allowed to start taking fluids and food orally. Absence of bowel sounds would indicate that the tube should remain in place because peristalsis has not yet returned. Absence of nausea and vomiting is not a criterion for judging whether or not gastric suction should be continued. Passage of mucus from the rectum will not occur in this client because the rectum is removed in this surgery. Absence of stomach drainage is not a criterion for judging whether or not gastric suction should be continued.
4. You have to teach ostomy self care to a patient with a colostomy. You tell the patient to measure and cut the wafer:

- B. About 1/16†larger than the stoma.
- C. About 1/8†larger than the stoma.
- D. About 1/4″ larger than the stoma.
Correct answer: C
Rationale: The wafer should be measured and cut about 1/8†larger than the stoma to ensure proper fit and prevent skin irritation.
5. Which of the following factors is believed to be linked to Crohn’s disease?
- A. Constipation
