Gastrointestinal System Nursing Exam Questions
1. A nurse is reviewing the results of serum laboratory studies drawn on a client who is suspected of having hepatitis. The nurse interprets that an elevation in which of the following studies is the most specific indicator of the disease?
- A. Erythrocyte sedimentation rate
- B. Serum bilirubin
- C. Hemoglobin
- D. Blood urea nitrogen
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.
2. The nurse is caring for a client following a Billroth II procedure. On review of the post-operative orders, which of the following, if prescribed, would the nurse question and verify?
- A. Irrigating the nasogastric tube
- B. Coughing a deep breathing exercises
- C. Leg exercises
- D. Early ambulation
Correct answer: A
Rationale: Irrigating the nasogastric tube is typically not recommended after a Billroth II procedure unless specifically ordered by a physician due to the risk of disrupting the surgical site.
3. You have a patient with achalasia (incomplete muscle relaxation of the GI tract, especially sphincter muscles). Which medications do you anticipate to administer?
- A. Isosorbide dinitrate (Isordil)
- B. Digoxin (Lanoxin)
- C. Captopril (Capoten)
- D. Propanolol (Inderal)
Correct answer: A
Rationale: Isosorbide dinitrate (Isordil) is a medication used to relax the muscles of the GI tract in patients with achalasia.
4. 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.
5. The nurse evaluates the client’s stoma during the initial post-op period. Which of the following observations should be reported immediately to the physician?
- A. The stoma is slightly edematous
- B. The stoma is dark red to purple
- C. The stoma oozes a small amount of blood
- D. The stoma does not expel stool
Correct answer: B
Rationale: A dark red to purple stoma may indicate compromised blood flow or ischemia, which requires immediate medical attention. This color change could be a sign of inadequate blood supply to the stoma tissue, leading to tissue damage or necrosis. Reporting this observation promptly is crucial to prevent further complications. Choices A, C, and D are not indicative of immediate medical concern. A slightly edematous stoma, oozing a small amount of blood, or not expelling stool may not be uncommon findings during the initial post-op period and can be managed without urgent intervention.
