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. A client is scheduled for a coronary artery bypass graft (CABG) surgery. The nurse should prepare the client by reinforcing information about which post-operative care measure?

• A. You will be on bed rest for the first 48 hours after surgery.
• B. You will be encouraged to cough and deep breathe frequently.
• C. You will be discharged within 24 hours if no complications arise.
• D. You will not be able to eat or drink for 24 hours after surgery.

Correct answer: B

Rationale: Encouraging the client to cough and deep breathe frequently is essential post-operative care to prevent respiratory complications such as atelectasis and pneumonia after CABG surgery. Choices A, C, and D are incorrect because post-CABG surgery, early mobilization is encouraged to prevent complications such as deep vein thrombosis (DVT) and pneumonia. Discharge within 24 hours is unlikely after CABG surgery, and early oral intake is encouraged to promote recovery and prevent complications.

3. A client with a diagnosis of heart failure is receiving digoxin (Lanoxin) and furosemide (Lasix). The LPN/LVN should closely monitor the client for which potential complication?

• A. Hyperkalemia
• B. Hypokalemia
• C. Hypernatremia
• D. Hyponatremia

Correct answer: B

Rationale: The correct answer is B: Hypokalemia. Furosemide is a loop diuretic that promotes the loss of potassium in the urine, potentially leading to hypokalemia. Hypokalemia increases the risk of digoxin toxicity, as digoxin's effects can be potentiated in the presence of low potassium levels. Monitoring for hypokalemia is crucial to prevent adverse effects and maintain the therapeutic effectiveness of digoxin in clients with heart failure. Choices A, C, and D are incorrect because furosemide does not typically cause hyperkalemia, hypernatremia, or hyponatremia. Instead, it commonly leads to hypokalemia due to increased potassium excretion.

4. The client is receiving furosemide (Lasix) for heart failure. What potential side effect should the nurse monitor for?

• A. Hypokalemia
• B. Hyperkalemia
• C. Hypernatremia
• D. Hypoglycemia

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, causes potassium loss, leading to hypokalemia. Monitoring potassium levels is crucial because hypokalemia can result in cardiac arrhythmias and muscle weakness. Choices B, C, and D are incorrect because furosemide does not typically cause hyperkalemia, hypernatremia, or hypoglycemia.

5. A client with heart failure is receiving digoxin. Which finding should indicate to the nurse that the client is experiencing digoxin toxicity?

• A. Constipation
• B. Blurred vision
• C. Bradycardia
• D. Dry cough

Correct answer: C

Rationale: Bradycardia is a hallmark sign of digoxin toxicity. Digoxin, a medication used to treat heart conditions, can lead to toxicity manifesting as bradycardia. Bradycardia occurs due to the drug's effect on slowing down the heart rate excessively. Constipation (Choice A) is not typically associated with digoxin toxicity. Blurred vision (Choice B) is more commonly linked to visual disturbances caused by digoxin, but it is not a defining sign of toxicity. Dry cough (Choice D) is not a recognized symptom of digoxin toxicity. It is crucial for the nurse to recognize the early signs of digoxin toxicity to prevent serious complications and provide appropriate interventions promptly.
