1. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). Which laboratory value indicates a therapeutic effect of the medication?

Correct answer: A

Rationale: An INR (International Normalized Ratio) of 2.5 indicates a therapeutic level for clients receiving warfarin (Coumadin) to prevent thromboembolism. It is essential to monitor INR levels regularly when on warfarin therapy to ensure that the blood's ability to clot is within the desired range to prevent both clotting and excessive bleeding.

2. In a patient with a history of chronic iron deficiency anemia requiring a recent blood transfusion and an extensive GI work-up, which statement is true based on their medications?

Correct answer: B

Rationale: The correct answer is B. Taking even a low dose of aspirin per day, such as 81 mg, can reduce the protective effect on the gastrointestinal mucosa that is gained from using a COX II selective inhibitor. Aspirin can increase the risk of gastrointestinal bleeding, which can counteract the benefits of COX II inhibitors in protecting the stomach lining.

3. A 28-year-old woman presents with abdominal pain, diarrhea, and weight loss. She has a history of recurrent mouth ulcers and a perianal fistula. What is the most likely diagnosis?

Correct answer: C

Rationale: The combination of symptoms including recurrent mouth ulcers, perianal fistula, abdominal pain, diarrhea, and weight loss is characteristic of Crohn's disease. These extra-intestinal manifestations, along with the gastrointestinal symptoms, point towards Crohn's disease rather than ulcerative colitis, irritable bowel syndrome, or diverticulitis.

4. When evaluating a client's understanding of wearing a Holter monitor, which statement made by the client would indicate to the nurse that the client understands the procedure?

Correct answer: A

Rationale: The correct answer is A. Recording symptoms that occur with activity is crucial when wearing a Holter monitor. This information helps in correlating symptoms with cardiac events, aiding in the diagnosis and treatment of the client's condition. The client's understanding of this aspect demonstrates comprehension of the procedure and its purpose.

5. A client has been diagnosed with an esophageal diverticulum after undergoing diagnostic imaging. When taking the health history, the nurse should expect the client to describe what sign or symptom?

Correct answer: B

Rationale: Regurgitation of undigested food is a typical symptom of esophageal diverticulum. This condition forms a pouch in the esophagus that can trap food, leading to regurgitation of undigested food. The other options are not typically associated with esophageal diverticulum.
