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 home care nurse is visiting a client with a diagnosis of pernicious anemia that developed as a result of gastric surgery. The nurse instructs the client that because the stomach lining produces a decreased amount of intrinsic factor in this disorder, the client will need

• A. Vitamin B12 injections.
• B. Vitamin B6 injections.
• C. An antibiotic.
• D. An antacid.

Correct answer: A

Rationale: A lack of the intrinsic factor needed to absorb vitamin B12 occurs in pernicious anemia. Vitamin B12 is needed for the maturation of red blood cells. Vitamin B6 is not necessarily needed for pernicious anemia and can be taken orally. An antibiotic and antacids may be prescribed for certain types of gastric ulcers.

3. The nurse provides medication instructions to a client with peptic ulcer disease. Which statement, if made by the client, indicates best understanding of the medication therapy?

• A. The cimetidine (Tagamet) will cause me to produce less stomach acid.
• B. Sucralfate (Carafate) will change the fluid in my stomach.
• C. Antacids will coat my stomach.
• D. Omeprazole (Prilosec) will coat the ulcer and help it heal.

Correct answer: A

Rationale: Cimetidine (Tagamet) a Histamine H2 receptor antagonist, will decrease the secretion of gastric acid. Sucralfate (Carafate) promotes healing by coating the ulcer. Antacids neutralize acid in the stomach. Omeprazole (Prilosec) inhibits gastric acid secretion.

4. Kevin has a history of peptic ulcer disease and vomits coffee-ground emesis. What does this indicate?

• A. He has fresh, active upper GI bleeding.
• B. He needs immediate saline gastric lavage.
• C. His gastric bleeding occurred 2 hours earlier.
• D. He needs a transfusion of packed RBCs.

Correct answer: C

Rationale: Coffee-ground emesis is a sign of upper gastrointestinal bleeding that occurred approximately 2 hours earlier. It results from the breakdown of blood in the stomach due to digestive enzymes, giving it a coffee-ground appearance. Choice A is incorrect because coffee-ground emesis indicates older, partially digested blood, not fresh active bleeding. Choice B is incorrect as gastric lavage is not indicated for coffee-ground emesis. Choice D is incorrect because a transfusion of packed RBCs is not the immediate management for this presentation.

5. A client presents to the emergency room, reporting that he has been vomiting every 30 to 40 minutes for the past 8 hours. Frequent vomiting puts him at risk for which of the following?

• A. Metabolic acidosis with hyperkalemia
• B. Metabolic acidosis with hypokalemia
• C. Metabolic alkalosis with hyperkalemia
• D. Metabolic alkalosis with hypokalemia

Correct answer: D

Rationale: Frequent vomiting can lead to metabolic alkalosis with hypokalemia due to the loss of stomach acid and electrolytes.
