Nursing Elites

1. Which lab value is essential for a patient receiving warfarin therapy?

• A. Monitor INR
• B. Monitor sodium levels
• C. Monitor potassium levels
• D. Monitor platelet count

Correct answer: A

Rationale: The correct answer is to monitor the INR (International Normalized Ratio) for a patient receiving warfarin therapy. INR monitoring is crucial to assess the effectiveness of warfarin in preventing blood clots while minimizing the risk of bleeding. Monitoring sodium levels (choice B), potassium levels (choice C), or platelet count (choice D) is not specifically essential for patients on warfarin therapy and does not provide direct information on the drug's anticoagulant effects.

2. A nurse is caring for a client with deep vein thrombosis who is prescribed warfarin. Which of the following client statements indicates a need for further teaching?

• A. I will avoid vitamin K-rich foods.
• B. I will avoid using aspirin while on this medication.
• C. I will monitor my blood pressure regularly.
• D. I will increase my intake of leafy greens.

Correct answer: D

Rationale: The correct answer is D. Warfarin's effectiveness is reduced by high intake of vitamin K-rich foods, so increasing their intake would contradict the treatment plan. Choices A, B, and C are all appropriate statements for a client on warfarin therapy. Avoiding vitamin K-rich foods helps maintain the medication's effectiveness, avoiding aspirin reduces the risk of bleeding, and monitoring blood pressure is essential for overall health monitoring.

3. A nurse is caring for an infant who has a prescription for continuous pulse oximetry. Which of the following is an appropriate action for the nurse to take?

• A. Place the infant under a radiant warmer
• B. Move the probe site every 3 hours
• C. Heat the skin one minute prior to placing the probe
• D. Place a sensor on the index finger

Correct answer: B

Rationale: The correct answer is to move the probe site every 3 hours. This action helps prevent skin breakdown and ensures accurate readings. Placing the infant under a radiant warmer (Choice A) is not necessary for pulse oximetry monitoring. Heating the skin before placing the probe (Choice C) can potentially cause burns in infants. Placing a sensor on the index finger (Choice D) is not the standard practice for continuous pulse oximetry in infants.

4. A charge nurse is teaching new staff members about factors that increase a client's risk of becoming violent. Which of the following risk factors should the nurse include as the best predictor of future violence?

• A. Experiencing delusions.
• B. Male gender.
• C. Previous violent behavior.
• D. A history of being in prison.

Correct answer: C

Rationale: The correct answer is C: Previous violent behavior. This is the best predictor of future violence as individuals who have a history of violent behavior are more likely to engage in violent acts in the future. While experiencing delusions and being male may contribute to an increased risk of violence in certain situations, they are not as strong predictors as a history of violence. Similarly, having a history of being in prison may indicate a higher likelihood of violence, but it is not as directly linked to future violent behavior as previous violent actions.

5. A nurse is caring for a client who is at risk for developing a deep vein thrombosis (DVT). Which of the following interventions should the nurse implement?

• A. Massage the client's legs every 2 hours.
• B. Instruct the client to sit with the legs crossed.
• C. Administer prophylactic antibiotics.
• D. Apply sequential compression devices to the client's legs.

Correct answer: D

Rationale: The correct answer is D: Apply sequential compression devices to the client's legs. Sequential compression devices help prevent venous stasis and reduce the risk of DVT by promoting blood flow in the legs. Massaging the client's legs every 2 hours (choice A) may dislodge a clot if present, leading to a higher risk of embolism. Instructing the client to sit with the legs crossed (choice B) can impede blood flow and increase the risk of DVT. Administering prophylactic antibiotics (choice C) is not indicated for preventing DVT, as antibiotics are used to treat infections caused by bacteria, not to prevent blood clots.
