Gastrointestinal System Nursing Exam Questions

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.

Correct Answer: A

Rationale: The client should be taught to include deodorizing foods in the diet, such as beet greens, parsley, buttermilk, and yogurt. Spinach also reduces odor but is a gas-forming food as well. Broccoli, cucumber, and eggs are gas-forming foods.

Correct Answer: D

Rationale: Intestinal tubes are not irrigated. Injecting air into the tube, applying water-soluble lubricant, and coiling extra tubing are appropriate nursing measures.

Correct Answer: B

Rationale: Small, frequent feedings are better tolerated by clients with ulcerative colitis as they lessen the amount of fecal material present in the gastrointestinal tract and decrease stimulation. The client does not need to maintain a daily record of intake and output unless an exacerbation of the disease occurs. A heating pad should not be applied to the intestine as it is inflamed. It is not inevitable that the client will require surgery to treat ulcerative colitis.

Correct Answer: B

Rationale: To prevent reflux of stomach acid into the esophagus, the nurse should advise the client to avoid foods and beverages that tend to increase stomach acid, such as coffee and alcohol. The nurse also should teach the client to avoid lying down after meals, which can aggravate reflux, and to take antacids after eating. The client doesn't need to limit fluids with meals as long as the fluids aren't gastric irritants.
