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 client has been prescribed atorvastatin (Lipitor) for hyperlipidemia. Which instruction should the nurse provide to the client?

• A. Take the medication in the morning with breakfast.
• B. Avoid drinking grapefruit juice while taking this medication.
• C. Increase your intake of dietary fiber while on this medication.
• D. Avoid eating foods high in potassium.

Correct answer: B

Rationale: The correct instruction for the nurse to provide to the client prescribed atorvastatin (Lipitor) for hyperlipidemia is to avoid drinking grapefruit juice while taking this medication. Grapefruit juice can interfere with the metabolism of atorvastatin, leading to an increased risk of side effects. It is crucial for the client to adhere to this instruction to ensure the effectiveness and safety of the treatment. Choices A, C, and D are incorrect because taking the medication with breakfast, increasing dietary fiber intake, and avoiding foods high in potassium are not specific instructions related to atorvastatin therapy for hyperlipidemia.

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

• A. Take the medication with food.
• B. Expect red-orange discoloration of body fluids.
• C. Monitor for signs of hyperglycemia.
• D. Avoid consuming dairy products.

Correct answer: B

Rationale: The correct answer is to inform the client to expect red-orange discoloration of body fluids when taking rifampin. Rifampin is known to cause this side effect, which is harmless but can be surprising to patients. It is important for the nurse to educate the client about this expected change to prevent unnecessary concern or alarm. Monitoring for hyperglycemia is not directly related to rifampin, and taking the medication with food or avoiding dairy products are not specific instructions for this medication.

4. A client has a history of left-sided heart failure. The nurse should look for the presence of which finding to determine whether the problem is currently active?

• A. Presence of ascites
• B. Bilateral lung crackles
• C. Jugular vein distention
• D. Pedal edema bilaterally

Correct answer: B

Rationale: When assessing a client with a history of left-sided heart failure, the presence of bilateral lung crackles is a key finding to determine if the condition is currently active. Crackles in the lungs indicate fluid accumulation, a common sign of left-sided heart failure due to pulmonary congestion. Choices A, C, and D are incorrect because ascites, jugular vein distention, and pedal edema are more commonly associated with right-sided heart failure.

5. 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.
