Nursing Elites

1. A client is scheduled for oral cholecystography. Which one of the following actions would the nurse plan to implement before the test?

• A. Have the client drink 1000 mL of water.
• B. Ask the client about possible allergies to iodine or shellfish.
• C. Administer an intravenous contrast agent the evening before the test.
• D. Administer tap-water enemas until clear.

Correct answer: B

Rationale: Iodine compounds used as radiographic contrast agents, such as iopanoic acid (Telepaque), should not be administered to the client with iodine and seafood allergies because anaphylaxis may occur.

2. The nurse is scheduling diagnostic tests for a client. If all of the following diagnostic tests are ordered, which would be performed last?

• A. Gallbladder series
• B. Barium enema
• C. Barium swallow
• D. Oral cholecystogram

Correct answer: C

Rationale: The correct answer is C, 'Barium swallow.' A barium swallow should be done after a barium enema or gallbladder series to prevent the contrast used in the barium swallow from obstructing the view of other organs. It takes several days for swallowed barium to pass completely out of the gastrointestinal tract. Choices A, B, and D are incorrect because a barium swallow should be the last test performed to ensure clear imaging without interference from residual contrast material.

3. A nurse is caring for a client diagnose with pancreatitis. The nurse anticipates that the client would not experience an elevation of which of the following enzymes?

• A. Lipase
• B. Lactase
• C. Amylase
• D. Trypsin

Correct answer: B

Rationale: Lactase is produced in the small intestine and aids in splitting neutral fats into glycerol and fatty acids. Lipase, amylase, and trypsin are produced in the pancreas and aid in the digestion of fats, starches, and proteins, respectively.

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. Fistulas are most common with which of the following bowel disorders?

• A. Crohn’s disease
• B. Diverticulitis
• C. Diverticulosis
• D. Ulcerative colitis

Correct answer: A

Rationale: Fistulas are most common in Crohn's disease due to the transmural inflammation that characterizes this condition.
