Nursing Elites

1. The nurse is caring for a client who is receiving heparin therapy. Which laboratory value should the nurse monitor to determine the effectiveness of the therapy?

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

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). While INR is commonly used to monitor the effectiveness of warfarin therapy, in the case of heparin therapy, the Partial Thromboplastin Time (PTT) is the preferred test. Choice A, Prothrombin Time (PT), measures the activity of the extrinsic pathway of coagulation and is not the best choice for monitoring heparin therapy. Choice D, Activated Partial Thromboplastin Time (aPTT), is similar to PTT and is used to monitor heparin therapy, but PTT is the more specific test. Therefore, monitoring PTT is crucial in determining the effectiveness and safety of heparin therapy.

2. The nurse observes a client in a wheelchair with a vest restraint in place. What nursing intervention is most important for the nurse to implement?

• A. Assess the need for continued restraint
• B. Check the client for urinary incontinence
• C. Determine skin integrity under the vest
• D. Perform range-of-motion exercises on extremities

Correct answer: A

Rationale: The correct answer is to assess the need for continued restraint. This is the most important nursing intervention as it ensures the client's safety and autonomy. Checking for urinary incontinence (Choice B) may be important but is not the priority in this situation. Determining skin integrity under the vest (Choice C) is essential but not as crucial as assessing the need for continued restraint. Performing range-of-motion exercises (Choice D) is important for client mobility but not the priority when a restraint is in place.

3. Which assessment finding is most indicative of deep vein thrombosis (DVT) in a client's right leg?

• A. Dorsiflexes the right foot and left on command
• B. A 3 by 5 cm ecchymosis area covering the right calf
• C. Right calf is 3 cm larger in circumference than the left
• D. Bilateral lower extremity has 3+ pitting edema

Correct answer: C

Rationale: The correct answer is C because a significant increase in the circumference of the right calf compared to the left calf is a classic sign of deep vein thrombosis (DVT). Option A is incorrect as dorsiflexing the right foot and left on command does not specifically indicate DVT. Option B describes an ecchymosis area which is more indicative of a bruise rather than DVT. Option D suggests bilateral lower extremity edema, which is not specific to DVT and can be seen in various conditions such as heart failure or renal issues.

4. The nurse is assessing a client who has a prescription for digoxin (Lanoxin). Which finding indicates that the client is at risk for digoxin toxicity?

• A. Heart rate of 60 beats per minute
• B. Blood pressure of 120/80 mm Hg
• C. Respiratory rate of 18 breaths per minute
• D. Serum potassium level of 3.0 mEq/L

Correct answer: D

Rationale: A low serum potassium level increases the risk of digoxin toxicity. Digoxin toxicity is more likely to occur in individuals with low potassium levels because potassium is crucial for proper heart function. A heart rate of 60 beats per minute, blood pressure of 120/80 mm Hg, and respiratory rate of 18 breaths per minute are within normal ranges and do not directly indicate an increased risk of digoxin toxicity.

5. A male client is admitted to the mental health unit because he experiences panic attacks when driving on the freeway. To attempt to desensitize this fear, what action should the nurse encourage the client to implement?

• A. Watch training videos of people driving in various environments
• B. Begin visualizing himself driving each route to the freeway
• C. Take antianxiety medication two hours before driving on freeways
• D. Get in the car with a support person and drive on a freeway during rush hour

Correct answer: B

Rationale: Visualization techniques, such as visualizing himself driving each route to the freeway, are commonly used in desensitization therapy to help clients gradually overcome their fears. Watching videos of others driving or taking medication do not actively involve the client in facing their fear, which is essential in desensitization therapy. Getting in the car with a support person during rush hour may exacerbate the client's anxiety rather than help in desensitization.
