Nursing Elites

1. A client with atrial fibrillation is receiving warfarin (Coumadin). The nurse should monitor which laboratory test to determine the effectiveness of the therapy?

• A. Prothrombin time (PT) and international normalized ratio (INR)
• B. Activated partial thromboplastin time (aPTT)
• C. Complete blood count (CBC)
• D. Fibrinogen level

Correct answer: A

Rationale: To monitor the effectiveness of warfarin therapy in a client with atrial fibrillation, the nurse should assess the Prothrombin time (PT) and international normalized ratio (INR) levels. These tests help determine the clotting ability of the blood and ensure that the client's anticoagulation levels are within the therapeutic range, reducing the risk of bleeding or clotting complications. Activated partial thromboplastin time (aPTT) (Choice B) is more commonly used to monitor heparin therapy. Complete blood count (CBC) (Choice C) provides information about the cellular components of blood but does not directly assess the effectiveness of warfarin therapy. Fibrinogen level (Choice D) is not typically used to monitor warfarin therapy; it reflects the level of fibrinogen in the blood, which is involved in the clotting process.

2. The nurse is caring for a client diagnosed with heart failure who is taking digoxin (Lanoxin). Which sign of digoxin toxicity should the nurse monitor for?

• A. Hypertension
• B. Bradycardia
• C. Hyperglycemia
• D. Insomnia

Correct answer: B

Rationale: The correct answer is B: Bradycardia. Bradycardia is a common sign of digoxin toxicity, as digoxin can cause decreased heart rate. Therefore, monitoring the client for signs of bradycardia is crucial. Choices A, C, and D are incorrect. Hypertension is not typically associated with digoxin toxicity; instead, hypotension may occur. Hyperglycemia is not a common sign of digoxin toxicity. Insomnia is also not a typical sign of digoxin toxicity; instead, some patients may experience visual disturbances, confusion, or other neurological symptoms.

3. The healthcare professional is collecting data on a client who was just admitted to the hospital with a diagnosis of coronary artery disease (CAD). The client reveals having been under a great deal of stress recently. What should the healthcare professional do next?

• A. Ask whether the client wants to seek counseling or therapy.
• B. Explore with the client the sources of stress in their life.
• C. Reassure the client that stress is common in today's world.
• D. Ask the client to make a list of stressors for later evaluation.

Correct answer: B

Rationale: It is important for the healthcare professional to explore the sources of stress with the client to develop an effective stress management plan tailored to the individual's specific stressors. By understanding the sources of stress, healthcare professionals can identify triggers, implement appropriate interventions, and support the client's overall well-being. Option A is not the immediate next step as exploring the sources of stress should come before suggesting counseling or therapy. Option C is dismissive of the client's feelings and does not address the need for personalized stress management. Option D delays the process by asking the client to make a list without actively engaging in a discussion to identify stressors.

4. The client has been prescribed warfarin (Coumadin) and is being educated about dietary restrictions. Which food should the client be advised to avoid or eat in consistent amounts?

• A. Bananas
• B. Spinach
• C. Oranges
• D. Yogurt

Correct answer: B

Rationale: Spinach is high in vitamin K, which can interfere with the effectiveness of warfarin. It is important for clients taking warfarin to maintain consistent levels of vitamin K intake to ensure the medication works properly. Foods rich in vitamin K, such as spinach, can counteract the effects of warfarin, leading to potential complications. Therefore, clients on warfarin are advised to either avoid or consume vitamin K-rich foods, like spinach, in consistent amounts to maintain the medication's efficacy. Bananas, oranges, and yogurt are not high in vitamin K and do not significantly impact the effectiveness of warfarin, making them safe options for clients taking this medication.

5. The healthcare provider is reviewing the medication orders for a client with angina pectoris. Which medication is typically prescribed to prevent angina attacks?

• A. Aspirin
• B. Nitroglycerin
• C. Atenolol
• D. Simvastatin

Correct answer: B

Rationale: Nitroglycerin is the medication typically prescribed to prevent angina attacks. It works by dilating blood vessels, increasing blood flow, and reducing the heart's workload, hence relieving angina symptoms. Aspirin is often used to prevent blood clots, not specifically to prevent angina attacks. Atenolol is a beta-blocker used to manage high blood pressure and chest pain but is not typically prescribed to prevent angina attacks. Simvastatin is a statin medication primarily used to lower cholesterol levels and is not indicated for preventing angina attacks.
