Nursing Elites

1. Which of the following mechanisms can facilitate the development of diverticulosis into diverticulitis?

• A. Treating constipation with chronic laxative use, leading to dependence on laxatives
• B. Chronic constipation causing an obstruction, reducing forward flow of intestinal contents
• C. Herniation of the intestinal mucosa, rupturing the wall of the intestine
• D. Undigested food blocking the diverticulum, predisposing the area to bacterial invasion

Correct answer: D

Rationale: The correct answer is D. Undigested food blocking the diverticulum can lead to bacterial invasion, causing inflammation and turning diverticulosis into diverticulitis. Choices A, B, and C do not directly facilitate the development of diverticulitis. Choice A involves a different mechanism related to laxative use, choice B describes a complication of chronic constipation but does not necessarily lead to diverticulitis, and choice C refers to a different condition involving herniation of the intestinal mucosa.

2. The 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 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. Which of the following symptoms best describes Murphy’s sign?

• A. Periumbilical ecchymosis exists
• B. On deep palpation and release, pain is elicited
• C. On deep inspiration, pain is elicited and breathing stops
• D. Abdominal muscles are tightened in anticipation of palpation

Correct answer: C

Rationale: Murphy's sign is described as pain elicited on deep inspiration when the examiner's fingers are placed under the right costal margin.

4. 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.

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.
