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

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. Which of the following complications of gastric resection should the nurse teach the client to watch for?

Correct answer: B

Rationale: Clients should be taught to watch for symptoms of dumping syndrome, a common complication after gastric resection.

4. The student nurse is participating in colorectal cancer-screening program. Which patient has the fewest risk factors for colon cancer?

5. Which of the following mechanisms can facilitate the development of diverticulosis into diverticulitis?

Correct answer: D

Rationale: The correct answer is D. Undigested food blocking the diverticulum can lead to bacterial invasion, causing inflammation and turning diverticulosis into diverticulitis. Choices A, B, and C do not directly facilitate the development of diverticulitis. Choice A involves a different mechanism related to laxative use, choice B describes a complication of chronic constipation but does not necessarily lead to diverticulitis, and choice C refers to a different condition involving herniation of the intestinal mucosa.
