1. A client who has ulcerative colitis has persistent diarrhea. He is thin and has lost 12 pounds since the exacerbation of his ulcerative colitis. The nurse should anticipate that the physician will order which of the following treatment approaches to help the client meet his nutritional needs?
- A. Initiate continuous enteral feedings
- B. Encourage a high protein, high-calorie diet
- C. Implement total parenteral nutrition
- D. Provide six small meals a day.
Correct answer: C
Rationale: Implementing total parenteral nutrition helps meet the nutritional needs of a client with persistent diarrhea and significant weight loss due to ulcerative colitis.
2. The nurse is caring for a client with a diagnosis of cirrhosis and is monitoring the client for signs of portal hypertension. Which initial sign, if noted in the client, indicates the presence of portal hypertension?
- A. Flat neck veins
- B. Hypotension
- C. Weak pulse
- D. Crackles on auscultation of the lungs
Correct answer: D
Rationale: Clinical signs and symptoms or portal hypertension are identical to those of heart failure and include jugular vein distention, lung crackles, and decreased perfusion to all organs. Initially, the client may have hypertension, flushed skin, and a bounding pulse.
3. When teaching a community group about measures to prevent colon cancer, which instruction should the nurse include?
- A. Limit fat intake to 20% to 25% of your total daily calories.
- B. Include 15 to 20 grams of fiber into your daily diet.
- C. Get an annual rectal examination after age 35.
- D. Undergo sigmoidoscopy annually after age 50.
Correct answer: A
Rationale: Limiting fat intake is a recommended measure to reduce the risk of colon cancer. Including fiber, undergoing annual rectal examinations, and sigmoidoscopy are also important, but limiting fat intake is directly related to reducing cancer risk.
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. A client with peptic ulcer is scheduled for a Vagotomy. The client asks the nurse about the purpose of this procedure. The nurse tells the client that the procedure
- A. Decreases food absorption in the stomach.
- B. Heals the gastric mucosa.
- C. Halts stress reactions.
- D. Reduces the stimulus to acid secretions.
Correct answer: D
Rationale: A vagotomy, or cutting of the vagus nerve, is done to eliminate parasympathetic stimulation of gastric secretion, thereby reducing the stimulus to acid secretions. Options A, B, and C are incorrect as a vagotomy does not affect food absorption, heal the gastric mucosa, or halt stress reactions.
