Nursing Elites

1. Which of the following definitions best describes diverticulosis?

• A. An inflamed outpouching of the intestine
• B. A noninflamed outpouching of the intestine
• C. The partial impairment of the forward flow of intestinal contents
• D. An abnormal protrusion of an organ through the structure that usually holds it

Correct answer: B

Rationale: The correct answer is B: 'A noninflamed outpouching of the intestine.' Diverticulosis refers to the presence of small, bulging pouches (diverticula) that can form in the lining of the digestive system, especially the colon. These pouches are typically noninflamed. Choice A is incorrect because it describes diverticulitis, which is the inflammation of these pouches. Choice C is incorrect as it defines bowel obstruction, not diverticulosis. Choice D is incorrect as it refers to a hernia, not diverticulosis.

2. A client with liver dysfunction is having difficulty with protein metabolism. The nurse anticipates that the results of which of the following serum laboratory studies will be elevated?

• A. Lactic acid
• B. Ammonia
• C. Albumin
• D. Lactase

Correct answer: B

Rationale: During deamination of proteins, the liver splits the amino group from the carbon-containing compound, which results in the formation of ammonia and a carbon residue. The liver then converts the toxic ammonia substance into urea, which can be excreted by the kidneys. Clients with liver dysfunction may have high serum ammonia levels as a result.

3. A client being treated for chronic cholecystitis should be given which of the following instructions?

• A. Increase rest
• B. Avoid antacids
• C. Increase protein in diet
• D. Use anticholinergics as prescribed

Correct answer: D

Rationale: Using anticholinergics as prescribed can help manage the symptoms of chronic cholecystitis.

4. Colon cancer is most closely associated with which of the following conditions?

• A. Appendicitis
• B. Hemorrhoids
• C. Hiatal hernia
• D. Ulcerative colitis

Correct answer: D

Rationale: Ulcerative colitis is a condition closely associated with an increased risk of developing colon cancer due to chronic inflammation of the colon.

5. 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.
