Nursing Elites

1. A client has been diagnosed with gastroesophageal reflux disease. The nurse interprets that the client has dysfunction of which of the following parts of the digestive system?

• A. Chief cells of the stomach
• B. Parietal cells of the stomach
• C. Lower esophageal sphincter
• D. Upper esophageal sphincter

Correct answer: C

Rationale: The lower esophageal sphincter is a functional sphincter that normally remains closed except when food or fluids are swallowed. If relaxation of this sphincter occurs, the client could experience symptoms of gastroesophageal reflux disease.

2. 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.

3. 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.

4. Which of the following activities should the nurse encourage the client with a peptic ulcer to avoid?

• A. Chewing gum.
• B. Smoking cigarettes.
• C. Eating chocolate.
• D. Taking acetaminophen (Tylenol).

Correct answer: B

Rationale: Cigarette smoking should be avoided because of its stimulatory effect on gastric secretions. Nicotine also increases the release of epinephrine, which leads to vasoconstriction. The client may chew gum if desired. The client may eat chocolate if desired. A client with a peptic ulcer should check with the physician before taking any over-the-counter drug, but acetaminophen does not typically cause gastric irritation.

5. A nurse is providing instructions to a client who will collect a stool specimen for occult blood. The nurse instructs the client to avoid which of the following for 3 days before the collection of the stool specimen?

• A. Milk products
• B. Hard cheese
• C. Turnips
• D. Cottage cheese

Correct answer: C

Rationale: The correct answer is C: Turnips. The nurse would instruct the client to avoid red meat, poultry, fish, turnips, horseradish, and foods such as fruits and vegetables for 3 days before and during testing. These products may alter test results. Choices A, B, and D are incorrect because they are not specifically mentioned as items to avoid before collecting a stool specimen for occult blood.
