1. Colon cancer is most closely associated with which of the following conditions?

• A. Appendicitis
• B. Hemorrhoids
• C. Hiatal hernia
• D. Ulcerative colitis

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.

• C. Chronic gastritis
• D. Ulcerative colitis

Correct answer: B

Rationale: The cobblestone appearance of the colon is characteristic of Crohn’s disease.

• A. Decreases food absorption in the stomach
