Nursing Elites

1. The client with atrial fibrillation is receiving warfarin (Coumadin). 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. Complete blood count (CBC)
• D. Fibrinogen level

Correct answer: A

Rationale: Monitoring Prothrombin time (PT) and international normalized ratio (INR) is crucial when a client is on warfarin therapy. These tests assess the clotting ability of the blood and help determine the appropriate dosage of warfarin to prevent complications such as bleeding or clotting events. PT and INR values within the therapeutic range indicate the effectiveness of warfarin in managing atrial fibrillation. Choice B, activated partial thromboplastin time (aPTT), is not typically used to monitor warfarin therapy; it is more commonly used to assess the effectiveness of heparin therapy. Choice C, complete blood count (CBC), does not directly assess the anticoagulant effect of warfarin. Choice D, fibrinogen level, is not a primary test for monitoring warfarin therapy; it is more relevant in assessing conditions like disseminated intravascular coagulation.

2. A client who has been taking prednisone is being assessed by a nurse. Which of the following findings should the nurse report to the provider?

• A. Weight gain
• B. Hyperglycemia
• C. Dry mouth
• D. Increased appetite

Correct answer: B

Rationale: Hyperglycemia is a significant finding in a client taking prednisone as it indicates the medication's impact on glucose metabolism. Prednisone can lead to increased blood sugar levels, which can be detrimental, especially in clients with diabetes or predisposition to hyperglycemia. Reporting hyperglycemia promptly to the healthcare provider is crucial for further evaluation and management to prevent complications. Choices A, C, and D are common side effects of prednisone but are not as concerning as hyperglycemia, which requires immediate attention to avoid potential adverse effects.

3. A client with a diagnosis of acute myocardial infarction (MI) is receiving thrombolytic therapy. The nurse monitors the client for which potential complication associated with this therapy?

• A. Hypertension
• B. Bleeding
• C. Hyperkalemia
• D. Hypoglycemia

Correct answer: B

Rationale: Thrombolytic therapy is associated with an increased risk of bleeding due to its mechanism of action in dissolving blood clots. Therefore, the nurse should closely monitor the client for any signs of hemorrhage, such as unexplained bruising, bleeding gums, or blood in the urine or stools. Hypertension is not a common complication of thrombolytic therapy. Hyperkalemia and hypoglycemia are also not typically associated with this therapy.

4. The LPN/LVN is assisting in the care of a client with a diagnosis of heart failure who is receiving digoxin (Lanoxin). Which laboratory result should the nurse monitor closely?

• A. Serum sodium
• B. Serum potassium
• C. Serum calcium
• D. Serum glucose

Correct answer: B

Rationale: The correct answer is serum potassium. Monitoring serum potassium levels is crucial when a client is receiving digoxin (Lanoxin) because low potassium levels can increase the risk of digoxin toxicity. Digoxin and low potassium levels can lead to serious cardiac complications, such as arrhythmias. Therefore, close monitoring of serum potassium is essential to prevent adverse effects and ensure the safe administration of digoxin in clients with heart failure. Serum sodium, serum calcium, and serum glucose levels are also important laboratory values to monitor in clients with heart failure, but they are not directly associated with the risk of digoxin toxicity. Monitoring these values helps in assessing overall health status, fluid balance, and metabolic functions in the client.

5. 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.
