1. Hepatic encephalopathy develops when the blood level of which substance increases?

• A. Ammonia
• B. Amylase
• C. Calcium
• D. Potassium

Correct answer: A

Rationale: Hepatic encephalopathy develops when the blood level of ammonia increases.

2. A 30-year-old woman is admitted to the hospital with complaints of severe abdominal cramping and diarrhea. The nurse evaluates the effectiveness of the patient's intravenous therapy. Which of the following laboratory tests BEST reflects hydration status?

• A. Erythrocyte sedimentation rate.
• B. White blood cell count.
• C. Hematocrit.
• D. Serum glucose.

Correct answer: C

Rationale: Hematocrit is the best indicator of hydration status because it reflects the proportion of red blood cells in the blood. An increased hematocrit indicates dehydration, as the blood becomes more concentrated due to fluid loss. Erythrocyte sedimentation rate (Choice A) is a nonspecific marker of inflammation, not hydration status. White blood cell count (Choice B) is an indicator of infection or inflammation. Serum glucose (Choice D) is used to monitor blood sugar levels, not hydration status.

3. The nurse is teaching the client how to perform a colostomy irrigation. To enhance the effectiveness of the irrigation and fecal returns, what measure should the nurse instruct the client to do?

• A. Increase fluid intake
• B. Reduce the amount of irrigation solution
• C. Perform the irrigation in the evening
• D. Place heat on the abdomen

Correct answer: A

Rationale: Increasing fluid intake helps to enhance the effectiveness of colostomy irrigation by softening the stool and promoting better fecal return.

4. The nurse is reviewing the record of a client with Crohn’s disease. Which of the following stool characteristics would the nurse expect to note documented in the client’s record?

• A. Chronic constipation
• B. Diarrhea
• C. Constipation alternating with diarrhea
• D. Stool constantly oozing from the rectum

Correct answer: B

Rationale: Crohn’s disease is characterized by nonbloody diarrhea of usually not more than four to five stools daily. Over time, the diarrhea episodes increase in frequency, duration, and severity. Chronic constipation (Choice A), constipation alternating with diarrhea (Choice C), and stool constantly oozing from the rectum (Choice D) are not characteristics typically associated with Crohn’s disease.

5. Of the following signs and symptoms of bowel obstruction, which is related primarily to small bowel obstruction rather than large bowel obstruction?

• A. Profuse vomiting.
• B. Cramping abdominal pain.
• C. Abdominal distention.
• D. High-pitched bowel sounds above the obstruction.

Correct answer: A

Rationale: Profuse vomiting is the classic sign of small bowel obstruction and rarely occurs with large bowel obstruction. Abdominal discomfort and distention are present in both small and large bowel obstructions, but distention is more common in large bowel obstruction. High-pitched bowel sounds indicate hyperperistalsis, which occurs early in obstruction.
