Nursing Elites

1. The client is receiving anticoagulant therapy for atrial fibrillation. Which laboratory test should be monitored to determine the effectiveness of the therapy?

• A. Prothrombin time (PT) and international normalized ratio (INR)
• B. Activated partial thromboplastin time (aPTT)
• C. Platelet count
• D. Erythrocyte sedimentation rate (ESR)

Correct answer: A

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of anticoagulant therapy in clients with atrial fibrillation. These tests help ensure that the client is within the therapeutic range and are commonly used to assess the clotting ability of the blood. Monitoring PT and INR levels allows healthcare providers to adjust anticoagulant dosages as needed to prevent complications such as bleeding or thrombosis. Activated partial thromboplastin time (aPTT) is more commonly used to monitor heparin therapy, not anticoagulant therapy for atrial fibrillation. Platelet count assesses the number of platelets in the blood and is not a direct indicator of anticoagulant therapy effectiveness. Erythrocyte sedimentation rate (ESR) is a nonspecific marker of inflammation and is not used to monitor anticoagulant therapy.

2. The client with a history of angina pectoris is being discharged after coronary artery bypass graft (CABG) surgery. Which statement by the client indicates a need for further teaching?

• A. I will avoid lifting heavy objects for at least 6 weeks.
• B. I will call the doctor if I develop a fever or drainage from my incisions.
• C. I will take my pain medication before doing any activities that might cause discomfort.
• D. I can resume my normal activities, including driving, as soon as I feel like it.

Correct answer: D

Rationale: The correct answer is D because after CABG surgery, patients need to follow specific guidelines for resuming activities, and driving is typically restricted for a certain period to ensure safety and proper recovery. Resuming normal activities too soon, including driving, can pose risks to the client's health and safety. It is essential to emphasize to the client the importance of following the healthcare provider's recommendations regarding activity restrictions post-surgery to prevent complications and promote optimal recovery. Choices A, B, and C are correct statements that align with post-CABG discharge instructions, emphasizing the importance of avoiding heavy lifting, monitoring for signs of infection, and managing pain effectively.

3. Which laboratory test should be monitored to evaluate the effectiveness of anticoagulant therapy in a client with deep vein thrombosis (DVT)?

• A. Complete blood count (CBC)
• B. Activated partial thromboplastin time (aPTT)
• C. Serum electrolytes
• D. Liver function tests

Correct answer: B

Rationale: Activated partial thromboplastin time (aPTT) is the laboratory test monitored to evaluate the effectiveness of anticoagulant therapy, particularly with heparin. It measures the time it takes for blood to clot, and monitoring aPTT helps ensure the therapeutic range is maintained to prevent clot formation and excessive bleeding. Choices A, C, and D are incorrect because a complete blood count (CBC) assesses overall health, serum electrolytes evaluate the body's electrolyte balance, and liver function tests assess liver health, none of which directly evaluate the effectiveness of anticoagulant therapy for DVT.

4. A nurse is providing teaching to a client who has a new prescription for warfarin. Which of the following statements should the nurse include?

• A. Avoid using a soft toothbrush.
• B. Report any signs of bleeding.
• C. Increase your intake of leafy green vegetables.
• D. Take the medication with food.

Correct answer: B

Rationale: The correct answer is B: 'Report any signs of bleeding.' When a patient is prescribed warfarin, it is essential to monitor for signs of bleeding as warfarin is an anticoagulant that increases the risk of bleeding. Choices A, C, and D are incorrect. Avoid using a soft toothbrush is not directly related to warfarin therapy, increasing the intake of leafy green vegetables can interfere with warfarin's effectiveness due to its vitamin K content, and taking warfarin with food is unnecessary as it can be taken with or without food.

5. The nurse is assisting in the care of a client with a history of angina pectoris who is receiving nitroglycerin patches. Which instruction should the nurse reinforce with the client?

• A. Apply the patch to a different site each time.
• B. Remove the patch at night to prevent tolerance.
• C. Use more than one patch if chest pain occurs.
• D. Shower with caution while wearing the patch.

Correct answer: B

Rationale: Removing the nitroglycerin patch at night is crucial to prevent the development of tolerance. Tolerance can occur when the body becomes accustomed to a constant level of the medication, reducing its effectiveness. By removing the patch at night, the client experiences a drug-free period, which helps prevent tolerance and maintains the effectiveness of the nitroglycerin for angina relief. Choices A, C, and D are incorrect because applying the patch to a different site each time helps prevent skin irritation, using more than one patch is not recommended unless instructed by the healthcare provider, and showering with caution is important to prevent dislodging the patch, but it is not the most critical instruction to prevent tolerance development.
