Nursing Elites

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?

• A. INR of 2.5.
• B. PTT of 45 seconds.
• C. Hemoglobin of 12 g/dL.
• D. Platelet count of 150,000/mm³.

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. A patient with deep vein thrombosis (DVT) is prescribed warfarin. Which dietary instruction should the nurse provide?

• A. Avoid foods high in vitamin K.
• B. Increase intake of dairy products.
• C. Limit intake of citrus fruits.
• D. Avoid high-sodium foods.

Correct answer: A

Rationale: Patients on warfarin should avoid foods high in vitamin K because vitamin K can interfere with the anticoagulant effect of the medication. Warfarin works by inhibiting vitamin K-dependent clotting factors, so consuming large amounts of vitamin K-rich foods may decrease the effectiveness of the medication. Choices B, C, and D are incorrect. Increasing intake of dairy products, limiting citrus fruits, or avoiding high-sodium foods are not directly related to the mechanism of action of warfarin or its dietary considerations.

3. A patient who is receiving chemotherapy for breast cancer develops thrombocytopenia. What should the nurse include in the care plan?

• A. Encourage light exercise.
• B. Avoid intramuscular injections.
• C. Do not administer aspirin.
• D. Use a soft toothbrush for oral care.

Correct answer: B

Rationale: Thrombocytopenia is a condition characterized by a low platelet count, which can lead to an increased risk of bleeding. To minimize this risk, patients with thrombocytopenia should avoid activities that can cause injury or bleeding, such as intramuscular injections. Encouraging light exercise can be beneficial, as it promotes circulation without increasing the risk of trauma. However, avoiding intramuscular injections is crucial to prevent bleeding episodes. Aspirin should be avoided as it can further impair platelet function, exacerbating the condition. Using a soft toothbrush for oral care is recommended to prevent gum bleeding in patients with thrombocytopenia.

4. A client with a history of peptic ulcer disease is admitted with severe abdominal pain. Which assessment finding should the nurse report to the healthcare provider immediately?

• A. Bowel sounds active in all quadrants.
• B. Blood pressure of 110/70 mm Hg.
• C. Rigid, board-like abdomen.
• D. Heart rate of 90 beats per minute.

Correct answer: C

Rationale: A rigid, board-like abdomen is a sign of peritonitis, a serious complication of peptic ulcer disease that can lead to sepsis and requires immediate intervention. This finding indicates a potential emergency situation that needs urgent medical attention to prevent further complications.

5. A client with type 2 diabetes mellitus is prescribed metformin (Glucophage). Which instruction should the nurse provide?

• A. Take the medication on an empty stomach.
• B. Limit your fluid intake while on this medication.
• C. Monitor your blood glucose levels regularly.
• D. Avoid eating foods high in potassium.

Correct answer: C

Rationale: Monitoring blood glucose levels regularly is crucial for clients with type 2 diabetes who are taking metformin. This helps assess the effectiveness of the medication in managing blood sugar levels and allows for timely adjustments in the treatment plan if needed. By monitoring blood glucose levels, the client and healthcare team can work together to achieve optimal diabetes control and prevent complications associated with uncontrolled blood sugar levels.
