Nursing Elites

1. A client is receiving warfarin for atrial fibrillation. Which of the following laboratory tests should the nurse expect to be ordered to monitor the effect of warfarin?

• A. Platelet count
• B. International normalized ratio (INR)
• C. Prothrombin time (PT)
• D. Partial thromboplastin time (PTT)

Correct answer: B

Rationale: The correct answer is B: International normalized ratio (INR). When a client is on warfarin therapy, the INR is monitored regularly to assess the anticoagulant effects of the medication. A therapeutic INR range for most indications is between 2.0 to 3.0. Choices A, C, and D are not typically used to monitor the effect of warfarin. Platelet count assesses the number of platelets in the blood, PT measures the clotting time of plasma, and PTT evaluates the intrinsic pathway of coagulation.

2. Which lab value is critical to monitor in patients receiving warfarin therapy?

• A. Monitor INR
• B. Monitor potassium levels
• C. Monitor platelet count
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial to monitor in patients receiving warfarin therapy. INR measures the blood's ability to clot and is used to ensure that patients are within the therapeutic range for warfarin therapy. This is important to prevent both clotting disorders and bleeding complications. Monitoring potassium levels (choice B) is not directly related to warfarin therapy. Platelet count (choice C) and sodium levels (choice D) are important parameters but are not as critical to monitor specifically for patients on warfarin therapy.

3. What is the priority intervention for a patient with fluid overload?

• A. Administer diuretics
• B. Administer IV fluids
• C. Provide oral fluids
• D. Provide chest physiotherapy

Correct answer: A

Rationale: The correct answer is to administer diuretics. Diuretics help reduce excess fluid in cases of fluid overload, making it the priority intervention. Administering additional IV fluids (choice B) would exacerbate the problem by adding more fluid. Providing oral fluids (choice C) is not the priority as the excess fluid needs to be removed first. Chest physiotherapy (choice D) is not the primary intervention for fluid overload.

4. A nurse is caring for a client who has a prescription for warfarin. Which of the following laboratory values should the nurse monitor?

• A. Prothrombin time (PT)
• B. Hemoglobin
• C. aPTT
• D. INR

Correct answer: D

Rationale: The correct answer is D, INR. The International Normalized Ratio (INR) is used to monitor the therapeutic effect of warfarin and to adjust the dose as needed. While Prothrombin time (PT) and activated Partial Thromboplastin Time (aPTT) are also related to coagulation studies, monitoring INR specifically helps in managing warfarin therapy. Hemoglobin, on the other hand, is not typically monitored in relation to warfarin therapy.

5. What is the primary action when a healthcare provider discovers a patient has fallen?

• A. Assess the patient for injuries
• B. Call for help immediately
• C. Document the fall
• D. Notify the healthcare provider

Correct answer: A

Rationale: When a healthcare provider discovers a patient has fallen, the primary action should be to assess the patient for injuries. This is crucial to determine the extent of harm and if immediate treatment is necessary. Calling for help is important, but assessing the patient's condition takes precedence to ensure the patient's safety and well-being. While documenting the fall and notifying the healthcare provider are essential steps, they come after assessing the patient's injuries.
