Nursing Elites

1. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin. Which laboratory value should the nurse monitor to assess the therapeutic effect of this medication?

• A. Platelet count
• B. Prothrombin time (PT)
• C. White blood cell count
• D. Hemoglobin level

Correct answer: B

Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.

2. Following a cardiac catheterization and placement of a stent in the right coronary artery, the nurse administers prasugrel, a platelet inhibitor, to the client. To monitor for adverse effects from the medication, which assessment is most important for the nurse to include in this client's care plan?

• A. Check platelet count
• B. Observe the color of urine
• C. Review liver function tests
• D. Monitor for bleeding

Correct answer: D

Rationale: Prasugrel is a platelet inhibitor, which increases the risk of bleeding. Monitoring for bleeding, particularly at the catheterization site and in other areas, is the most important assessment following administration of the drug. Checking platelet count and observing urine color are relevant but not as immediate. Reviewing liver function tests is not directly related to the adverse effects of prasugrel.

3. A client presents to the clinic with a large abscess on the right thigh. The healthcare provider incises and drains the abscess. Which instruction should the nurse provide to the client upon discharge?

• A. Avoid showering until the wound is completely closed
• B. Perform daily wound care and dressing changes
• C. Apply heat to the wound for 15 minutes twice a day
• D. Take the prescribed antibiotic until the wound is fully healed

Correct answer: B

Rationale: After incision and drainage of an abscess, it is crucial to perform daily wound care and dressing changes to prevent infection and promote healing. Avoiding showering until the wound is completely closed (choice A) may not be practical or necessary. Applying heat to the wound (choice C) can increase the risk of infection and delay healing. While taking the prescribed antibiotic (choice D) is important, wound care and dressing changes are more directly related to promoting healing and preventing complications.

4. A client with deep vein thrombosis (DVT) is prescribed heparin. What lab value should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT).
• B. Partial thromboplastin time (PTT).
• C. International Normalized Ratio (INR).
• D. Hemoglobin and hematocrit.

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.

5. A client on mechanical ventilation is experiencing high-pressure alarms. What action should the nurse implement first?

• A. Check the client's oxygen saturation.
• B. Assess the client's endotracheal tube for obstruction.
• C. Reposition the client to relieve pressure.
• D. Suction the client's airway.

Correct answer: B

Rationale: The correct answer is to assess the client's endotracheal tube for obstruction. When a client on mechanical ventilation experiences high-pressure alarms, the first action should be to check for any potential obstructions in the airway, which can trigger the alarms. Checking the oxygen saturation (Choice A) is important but not the priority when dealing with high-pressure alarms. Repositioning the client (Choice C) may be necessary later but should not be the initial action. Suctioning the client's airway (Choice D) should only be done after assessing for and addressing any obstructions in the endotracheal tube.
