Nursing Elites

1. 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.

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. A 30-year-old woman is admitted to the hospital with complaints of severe abdominal cramping and diarrhea. The nurse evaluates the effectiveness of the patient's intravenous therapy. Which of the following laboratory tests BEST reflects hydration status?

• A. Erythrocyte sedimentation rate.
• B. White blood cell count.
• C. Hematocrit.
• D. Serum glucose.

Correct answer: C

Rationale: Hematocrit is the best indicator of hydration status because it reflects the proportion of red blood cells in the blood. An increased hematocrit indicates dehydration, as the blood becomes more concentrated due to fluid loss. Erythrocyte sedimentation rate (Choice A) is a nonspecific marker of inflammation, not hydration status. White blood cell count (Choice B) is an indicator of infection or inflammation. Serum glucose (Choice D) is used to monitor blood sugar levels, not hydration status.

4. The nurse is performing a colostomy irrigation on a client. During the irrigation, a client begins to complain of abdominal cramps. Which of the following is the most appropriate nursing action?

• A. Notify the physician
• B. Increase the height of the irrigation
• C. Stop the irrigation temporarily.
• D. Medicate with dilaudid and resume the irrigation

Correct answer: C

Rationale: If a client experiences abdominal cramps during a colostomy irrigation, it is appropriate to stop the irrigation temporarily to allow the cramps to subside.

5. Which of the following diets is most commonly associated with colon cancer?

• A. Low-fiber, high fat
• B. Low-fat, high-fiber
• C. Low-protein, high-carbohydrate
• D. Low carbohydrate, high protein

Correct answer: A

Rationale: A low-fiber, high-fat diet is most commonly associated with an increased risk of colon cancer.
