Nursing Elites

1. The most important pathophysiologic factor contributing to the formation of esophageal varices is:

• A. Decreased prothrombin formation
• B. Decreased albumin formation by the liver
• C. Portal hypertension
• D. Increased central venous pressure

Correct answer: C

Rationale: Portal hypertension is the most important pathophysiologic factor contributing to the formation of esophageal varices.

2. A client has a nasogastric tube inserted at the time of abdominal perineal resection with permanent colostomy. This tube will most likely be removed when the client demonstrates:

• A. Absence of nausea and vomiting.
• B. Passage of mucus from the rectum.
• C. Passage of flatus and feces from the colostomy.
• D. Absence of stomach drainage for 24 hours.

Correct answer: C

Rationale: A sign indicating that a client's colostomy is open and ready to function is passage of feces and flatus. When this occurs, gastric suction is ordinarily discontinued, and the client is allowed to start taking fluids and food orally. Absence of bowel sounds would indicate that the tube should remain in place because peristalsis has not yet returned. Absence of nausea and vomiting is not a criterion for judging whether or not gastric suction should be continued. Passage of mucus from the rectum will not occur in this client because the rectum is removed in this surgery. Absence of stomach drainage is not a criterion for judging whether or not gastric suction should be continued.

3. A 40-year-old male client has been hospitalized with peptic ulcer disease. He is being treated with a histamine receptor antagonist (cimetidine), antacids, and diet. The nurse doing discharge planning will teach him that the action of cimetidine is to:

• A. Reduce gastric acid output
• B. Protect the ulcer surface
• C. Inhibit the production of hydrochloric acid (HCl)
• D. Inhibit vagus nerve stimulation

Correct answer: C

Rationale: Cimetidine inhibits the production of hydrochloric acid (HCl), which helps to treat peptic ulcer disease.

4. The client being seen in a physician’s office has just been scheduled for a barium swallow the next day. The nurse writes down which of the following instructions for the client to follow before the test?

• A. Fast for 8 hours before the test.
• B. Eat a regular supper and breakfast.
• C. Continue to take all oral medications as scheduled.
• D. Monitor own bowel movement pattern for constipation

Correct answer: A

Rationale: A barium swallow is an x-ray study that uses a substance called barium for contrast to highlight abnormalities in the gastrointestinal tract. The client should fast for 8 to 12 hours before the test, depending on physician instructions. Most oral medications also are withheld before the test. After the procedure the nurse must monitor for constipation, which can occur as a result of the presence of barium in the gastrointestinal tract.

5. The nurse is monitoring a client for the early signs and symptoms for dumping syndrome. Which symptom indicates this occurrence?

• A. Abdominal cramping and pain
• B. Bradycardia and indigestion
• C. Sweating and pallor
• D. Double vision and chest pain

Correct answer: C

Rationale: Early manifestations of dumping syndrome occur 5 to 30 minutes after eating. Symptoms include vertigo, tachycardia, syncope, sweating, pallor, palpitations, and the desire to lie down.
