Nursing Elites

1. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). Which laboratory value indicates a therapeutic effect of the medication?

• A. INR of 2.5.
• B. PTT of 45 seconds.
• C. Hemoglobin of 12 g/dL.
• D. Platelet count of 150,000/mm³.

Correct answer: A

Rationale: An INR (International Normalized Ratio) of 2.5 indicates a therapeutic level for clients receiving warfarin (Coumadin) to prevent thromboembolism. It is essential to monitor INR levels regularly when on warfarin therapy to ensure that the blood's ability to clot is within the desired range to prevent both clotting and excessive bleeding.

2. Aspirin is prescribed for a 9-year-old child with rheumatic fever to control the inflammatory process, promote comfort, and reduce fever. What intervention is most important for the nurse to implement?

• A. Instruct the parents to hold the aspirin until the child has first had a tepid sponge bath.
• B. Administer the aspirin with at least two ounces of water or juice.
• C. Notify the healthcare provider if the child complains of ringing in the ears.
• D. Advise the parents to question the child about seeing yellow halos around objects.

Correct answer: C

Rationale: In children, ringing in the ears (tinnitus) can be a sign of aspirin toxicity. Aspirin toxicity can be particularly concerning in children and can lead to serious complications. Therefore, it is crucial for the nurse to prioritize monitoring for signs of aspirin toxicity, such as tinnitus, and promptly notify the healthcare provider if such symptoms occur.

3. 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.

4. A patient is being cared for after bariatric surgery, and the healthcare provider is assessing for hemorrhage. What is a sign of hemorrhage?

• A. Increase in blood pressure
• B. Frank red bleeding from the surgical site
• C. Clear drainage from the surgical wound
• D. Decrease in heart rate

Correct answer: B

Rationale: Frank red bleeding from the surgical site is a significant sign of hemorrhage that warrants immediate attention. It indicates active bleeding that needs to be addressed promptly to prevent further complications.

5. A client with hypothyroidism is prescribed levothyroxine (Synthroid). Which instruction should the nurse provide?

• A. Take the medication with a meal.
• B. Take the medication at bedtime.
• C. Take the medication on an empty stomach.
• D. Take the medication with an antacid.

Correct answer: C

Rationale: The correct instruction for a client prescribed levothyroxine (Synthroid) is to take the medication on an empty stomach. This ensures optimal absorption of levothyroxine. Taking it with a meal can interfere with absorption due to food interactions. Taking it at bedtime may lead to inconsistent absorption as it should be taken at the same time every day in the morning. Taking it with an antacid can reduce the absorption of levothyroxine, making it less effective.
