Gastrointestinal System Nursing Exam Questions

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.

Correct Answer: B

Rationale: During the first 24 to 72 hours following surgery, mucus and serosanguineous drainage are expected from the stoma. Documenting the amount and characteristics of the drainage is appropriate. The nurse does not need to notify the physician because this is an expected finding. Applying ice or pressure to the site is not necessary.

Correct Answer: A

Rationale: Following this procedure, the nurse monitors the client's vital signs closely for indications of hemorrhage and observes the needle insertion site for bleeding and bile leakage. A sandbag is placed over the insertion site to prevent bleeding. The client is maintained on bedrest, and oral intake is avoided in the immediate postprocedure period in case surgery is necessary to control hemorrhage of bile extravasation.

Correct Answer: A

Rationale: As the nasogastric tube is passed through the oropharynx, the gag reflex is stimulated, which may cause coughing, gagging, or choking. Instead of passing through to the esophagus, the nasogastric tube may coil around itself in the oropharynx, or it may enter the larynx and obstruct the airway, pulling the tube back slightly will remove it from the larynx; advancing the tube might position it in the trachea. Swallowing closes the epiglottis over the trachea and helps move the tube into the esophagus. Slow breathing helps the client relax to reduce the gag response. The nurse should check the back of the client's throat to note if the tube has coiled. The tube may be advanced after the client relaxes.

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.
