1. Hepatic encephalopathy develops when the blood level of which substance increases?

• A. Ammonia
• B. Amylase
• C. Calcium
• D. Potassium

Correct answer: A

Rationale: Hepatic encephalopathy develops when the blood level of ammonia increases.

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. Which of the following types of diets is implicated in the development of diverticulosis?

• A. Low-fiber diet
• B. High-fiber diet
• C. High-protein diet
• D. Low-carbohydrate diet

Correct answer: A

Rationale: A low-fiber diet is implicated in the development of diverticulosis because it leads to harder stools and increased pressure in the colon. The lack of fiber results in decreased bulk and slower transit time, predisposing individuals to constipation and the formation of diverticula. High-fiber diets, on the other hand, promote regular bowel movements and help prevent diverticular disease. High-protein and low-carbohydrate diets do not have a direct association with diverticulosis.

4. Crohn’s disease can be described as a chronic relapsing disease. Which of the following areas in the GI system may be involved with this disease?

• A. The entire length of the large colon
• B. Only the sigmoid area
• C. The entire large colon through the layers of mucosa and submucosa
• D. The small intestine and colon; affecting the entire thickness of the bowel

Correct answer: D

Rationale: Crohn's disease can affect any part of the gastrointestinal tract from the mouth to the anus, but it commonly affects the small intestine and colon, involving the entire thickness of the bowel wall.

• B. Begin feeding slowly to prevent cramping.
• C. Get an X-ray of the tip of the tube within 24 hours.
• D. Clamp off the tube until the feedings begin.

Correct answer: A

Rationale: Immediately after inserting an NG tube for enteral feedings, aspirate for gastric secretions to confirm proper placement.
