Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory test should the nurse monitor to determine the effectiveness of the medication?

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

Correct answer: B

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of warfarin (Coumadin) therapy. These tests help assess the clotting time and the desired anticoagulant effect of the medication. Monitoring PT and INR levels is crucial to ensure that the client is within the therapeutic range, reducing the risk of bleeding or clotting complications associated with warfarin therapy. Platelet count (Choice A) measures the number of platelets in the blood and is not specific for monitoring warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice C) is more commonly used to monitor heparin therapy, not warfarin. Fibrinogen level (Choice D) assesses the amount of fibrinogen in the blood and is not a specific test for monitoring warfarin therapy.

2. A client with deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to assess the effectiveness of the therapy?

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

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the appropriate laboratory test to monitor the effectiveness of heparin therapy. Heparin works by prolonging the clotting time, which is reflected in the aPTT results. Monitoring aPTT helps ensure the patient is within the therapeutic range and not at risk of bleeding or clotting complications. Prothrombin time (PT) (Choice A) primarily measures the extrinsic pathway of coagulation and is used to monitor warfarin therapy, not heparin. Platelet count (Choice B) assesses the number of platelets present in the blood and is not specific to monitoring heparin therapy. International normalized ratio (INR) (Choice D) is used to monitor warfarin therapy, not heparin.

3. A client with a history of atrial fibrillation is prescribed dabigatran (Pradaxa). Which instruction should the nurse include in the client's teaching?

• A. Take the medication with food to improve absorption.
• B. Avoid foods high in vitamin K.
• C. Take the medication at the same time each day.
• D. Increase your intake of high-potassium foods.

Correct answer: C

Rationale: The correct instruction for the nurse to include in the client's teaching regarding dabigatran (Pradaxa) is to take the medication at the same time each day. This ensures a consistent blood level and effectiveness of the medication, which is crucial in managing atrial fibrillation and preventing complications. It helps maintain a steady therapeutic effect and reduces the risk of erratic drug levels in the body.

4. The healthcare provider prescribes naproxen (Naprosyn) 500 mg PO twice a day for a client with osteoarthritis. During a follow-up visit one month later, the client tells the nurse, 'The pills don't seem to be working. They are not helping the pain at all.' Which factor should influence the nurse's response?

• A. Noncompliance is probably affecting optimal medication effectiveness.
• B. Drug dosage is inadequate and needs to be increased to three times a day.
• C. The drug needs 4 to 6 weeks to reach therapeutic levels in the bloodstream.
• D. NSAID response is variable, and trying another NSAID may be more effective.

Correct answer: D

Rationale: Different NSAIDs work differently in individuals. If a patient is not experiencing relief with one NSAID, switching to a different one may provide better pain management. This variability in response is common among NSAIDs due to individual differences in drug metabolism and efficacy.

5. A client with long-standing obesity has been prescribed phentermine/topiramate-ER. What statement by the client suggests that further health education is necessary?

• A. I'm so relieved to start this medication. I really don't like having to exercise or change what I eat.
• B. It's hard to believe that there are actually medications that can treat obesity.
• C. I'm a bit nervous to start this medication because I know I'll need blood tests sometimes.
• D. I'm going to have to do some rearranging of my finances to make sure I can afford this medication.

Correct answer: A

Rationale: Choice A suggests the need for further health education as the client expresses a reluctance to exercise or change dietary habits, indicating a lack of understanding about the importance of lifestyle modifications in conjunction with medication for effective weight management. It is important for the client to comprehend that a holistic approach, including lifestyle changes, is crucial for successful obesity treatment and long-term health benefits.
