Nursing Elites

1. The client has atrial fibrillation and is receiving warfarin (Coumadin) therapy. Which laboratory test should be monitored to evaluate the effectiveness of the warfarin therapy?

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

Correct answer: A

Rationale: Monitoring the Prothrombin time (PT) and international normalized ratio (INR) is crucial for assessing the effectiveness of warfarin therapy. These tests help determine the clotting ability of the blood and ensure that the client is within the desired therapeutic range to prevent clotting events or bleeding complications. Activated partial thromboplastin time (aPTT) (Choice B) is more commonly used to monitor heparin therapy, not warfarin. Complete blood count (CBC) (Choice C) and fibrinogen levels (Choice D) do not directly assess the effectiveness of warfarin therapy in the same way that PT and INR do.

2. Before administering digoxin (Lanoxin) to a client diagnosed with heart failure, the nurse should perform which assessment?

• A. Check the blood pressure.
• B. Obtain an electrocardiogram (ECG).
• C. Assess the apical pulse.
• D. Review the latest electrolyte levels.

Correct answer: C

Rationale: Assessing the apical pulse is crucial before administering digoxin because the medication can lead to bradycardia. Monitoring the apical pulse helps determine the heart rate, and digoxin is typically withheld if the pulse is below 60 beats per minute. This assessment is essential to prevent potential adverse effects associated with digoxin administration. Checking the blood pressure (Choice A) is important but not specific to digoxin administration. Obtaining an electrocardiogram (ECG) (Choice B) may provide valuable information but is not the primary assessment needed before administering digoxin. Reviewing the latest electrolyte levels (Choice D) is important for assessing the overall condition but is not the immediate assessment required before administering digoxin.

3. A client is diagnosed with thrombophlebitis. The nurse should tell the client that which prescription is indicated?

• A. Bed rest, with bathroom privileges only
• B. Bed rest, keeping the affected extremity flat
• C. Bed rest, with elevation of the affected extremity
• D. Bed rest, with the affected extremity in a dependent position

Correct answer: C

Rationale: The correct answer is C: Bed rest, with elevation of the affected extremity. Elevating the affected extremity is crucial in managing thrombophlebitis as it helps reduce swelling and promotes venous return. By elevating the affected extremity, the gravitational force assists in venous blood flow back to the heart, thereby reducing the risk of complications associated with thrombophlebitis. Choices A, B, and D are incorrect because they do not address the need for elevation, which is specifically beneficial in the management of thrombophlebitis.

4. 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.

5. The client with a diagnosis of heart failure is receiving furosemide (Lasix). Which laboratory value is most important for the nurse to monitor?

• A. Blood glucose
• B. Serum sodium
• C. Serum potassium
• D. Blood urea nitrogen (BUN)

Correct answer: C

Rationale: The correct answer is C: Serum potassium. When a client is receiving furosemide, a loop diuretic, it can lead to potassium loss. Monitoring the serum potassium levels is crucial to prevent life-threatening complications such as cardiac arrhythmias. Blood glucose (Choice A) is not directly impacted by furosemide. Serum sodium (Choice B) may be affected, but monitoring potassium is more critical due to the risk of arrhythmias. Blood urea nitrogen (BUN) (Choice D) is important for assessing kidney function but is not the most crucial value to monitor in a client taking furosemide.
