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

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 client with a new prescription for levothyroxine is receiving discharge teaching. Which of the following client statements indicates an understanding of the teaching?

Correct answer: B

Rationale: The correct answer is B. Levothyroxine should be taken every morning before breakfast to enhance absorption and maintain consistent thyroid hormone levels. Option A is incorrect because levothyroxine should be taken on an empty stomach. Option C is incorrect because chest pain is not a common side effect of levothyroxine and stopping the medication abruptly can be harmful. Option D is incorrect because taking levothyroxine at bedtime may result in decreased absorption due to interactions with food and other medications.

3. A nurse is caring for a client who has a prescription for clozapine. Which of the following laboratory values should the nurse monitor?

Correct answer: B

Rationale: The correct answer is to monitor the WBC count. Clozapine can cause agranulocytosis, a severe decrease in WBC count, which can increase the risk of infection. Monitoring the WBC count is essential to detect this potentially life-threatening condition early. Monitoring blood glucose levels (Choice A) is not directly related to clozapine use. Platelet count (Choice C) and hemoglobin levels (Choice D) are not typically affected by clozapine and are not the priority for monitoring in this case.

4. A client with Parkinson's disease is receiving physical therapy. Which statement by the client indicates the need for a referral to physical therapy?

Correct answer: C

Rationale: The correct answer is C because freezing of feet while walking is a sign of impaired mobility, indicating the need for physical therapy in clients with Parkinson's disease. Choices A, B, and D are symptoms commonly associated with Parkinson's disease but do not specifically indicate the need for immediate referral to physical therapy.

5. What is the priority nursing assessment for a patient who has just returned from surgery?

Correct answer: A

Rationale: The correct answer is to monitor the patient's respiratory rate. This assessment is essential as it ensures that the patient is breathing adequately post-surgery. Maintaining a patent airway and adequate oxygenation are the top priorities in the immediate postoperative period. Monitoring blood pressure, checking the surgical site, or monitoring heart rate are important assessments but are not the priority immediately upon the patient's return from surgery.
