Nursing Elites

1. A client with atrial fibrillation is receiving warfarin (Coumadin). The nurse should reinforce which instruction?

• A. Avoid foods high in vitamin K.
• B. Increase intake of dairy products.
• C. Limit intake of high-fiber foods.
• D. Avoid protein-rich foods.

Correct answer: A

Rationale: The correct answer is A: Avoid foods high in vitamin K. Clients taking warfarin need to be cautious with their vitamin K intake because vitamin K can counteract the effects of the medication. Therefore, it is essential to avoid foods high in vitamin K to maintain the therapeutic effects of warfarin. Choice B is incorrect because increasing dairy product intake is not specifically related to warfarin therapy. Choice C is incorrect as high-fiber foods do not interfere with warfarin therapy. Choice D is incorrect as protein-rich foods are not contraindicated with warfarin therapy.

2. The nurse is assisting in the care of a client experiencing an acute myocardial infarction (MI). Which medication would the nurse expect to be administered to help reduce myocardial oxygen demand?

• A. Aspirin
• B. Morphine
• C. Atropine
• D. Lidocaine

Correct answer: B

Rationale: In the context of an acute myocardial infarction (MI), morphine is administered to relieve pain and reduce myocardial oxygen demand. By alleviating pain and anxiety, morphine helps reduce oxygen demand on the heart, which is beneficial in the setting of an MI. Aspirin, commonly used for its antiplatelet effects, helps inhibit platelet aggregation and is crucial in the management of MI to prevent further clot formation. Atropine is a medication used to treat symptomatic bradycardia by increasing heart rate, not commonly indicated in the management of acute MI. Lidocaine is used for ventricular dysrhythmias and is not typically given to reduce myocardial oxygen demand in an acute MI scenario.

3. The nurse is assisting with the care of a client who is on a continuous heparin infusion for deep vein thrombosis (DVT). Which laboratory test should the nurse monitor to evaluate the effectiveness of the therapy?

• A. Prothrombin time (PT)
• B. Activated partial thromboplastin time (aPTT)
• C. International normalized ratio (INR)
• D. Platelet count

Correct answer: B

Rationale: To evaluate the effectiveness of heparin therapy in a client with DVT, the nurse should monitor the activated partial thromboplastin time (aPTT). The aPTT test helps ensure that the dose of heparin is within the therapeutic range, which is essential for preventing clot formation or excessive bleeding. Monitoring aPTT is crucial in managing patients on heparin therapy to maintain the delicate balance between preventing thrombosis and avoiding hemorrhage. Prothrombin time (PT) and International normalized ratio (INR) are more indicative of warfarin therapy effectiveness, not heparin. Platelet count assesses platelet levels and function, not the effectiveness of heparin therapy for DVT.

4. A client has a new prescription for amlodipine. Which of the following instructions should the nurse include?

• A. Take the medication with food.
• B. Monitor blood pressure daily.
• C. Increase intake of potassium-rich foods.
• D. Avoid consuming grapefruit juice.

Correct answer: B

Rationale: The correct answer is B: 'Monitor blood pressure daily.' When a client is prescribed amlodipine, it is essential to monitor their blood pressure regularly. Amlodipine is known to cause hypotension, so monitoring blood pressure helps ensure it stays within the desired range to prevent complications associated with low blood pressure. Choice A is incorrect because amlodipine can be taken with or without food. Choice C is incorrect as increasing potassium intake is not a specific instruction related to amlodipine. Choice D is incorrect as grapefruit juice interactions are not typically a concern with amlodipine.

5. The healthcare professional is reinforcing teaching for a client with peripheral artery disease (PAD). Which statement by the client indicates a need for further teaching?

• A. I will keep my legs elevated on pillows while resting.
• B. I will avoid crossing my legs when sitting.
• C. I will wear loose-fitting, comfortable shoes.
• D. I will avoid exposure to cold temperatures.

Correct answer: A

Rationale: The correct answer is A. Elevating the legs can decrease blood flow in clients with PAD, worsening symptoms. Therefore, advising the client to keep the legs elevated on pillows while resting is incorrect and can exacerbate the condition. Choice B is correct as avoiding crossing legs helps prevent circulation restriction. Choice C is correct as wearing loose-fitting shoes promotes circulation. Choice D is correct as avoiding exposure to cold temperatures helps prevent vasoconstriction, which can worsen PAD symptoms.
