Gastrointestinal System Nursing Exam Questions

Correct Answer: B

Rationale: Impaired skin integrity would be the priority nursing diagnosis for daily care of the colostomy because the effluent from the colostomy can be irritating to the skin. Diarrhea isn't a concern at this point. The client will be allowed nothing by mouth until peristalsis returns. The client should get out of bed on the first postoperative day, so mobility shouldn't be a problem.

Correct Answer: D

Rationale: Evaluating the absorption of the last feeding is important because administration of a tube feeding to a full stomach could result in overdistention, thus predisposing the client to regurgitation and possible aspiration.

Correct Answer: D

Rationale: The most appropriate response in this situation is to seek clarification from the client by saying, 'I'm not sure that I don't understand. Would you please explain?' This response shows empathy and a willingness to listen, encouraging the client to elaborate on their concerns. False reassurance (Choice A) is not helpful as it dismisses the client's feelings. Suggesting to talk more with the doctor (Choice B) may deflect from addressing the client's immediate concerns. Expressing disbelief (Choice C) can create a barrier to open communication, making the client feel unsupported.

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: C

Rationale: Laboratory indicators of hepatitis include elevated liver enzymes, serum bilirubin level, and erythrocyte sedimentation rate is nonspecific test that indicates the presence of inflammation somewhere in the body. Elevated blood urea nitrogen may indicate renal dysfunction. A hemoglobin level is unrelated to this diagnosis.
