1. Which lab value is critical for monitoring warfarin therapy?

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.

2. A client is 1 day postoperative following abdominal surgery. Which of the following actions should the nurse take to prevent respiratory complications?

Correct answer: B

Rationale: Encouraging the use of an incentive spirometer is crucial for preventing respiratory complications postoperatively, such as atelectasis. Instructing the client to avoid deep breathing exercises (choice A) is incorrect as deep breathing exercises help prevent respiratory complications. Assisting with ambulation every 2 hours (choice C) is important for preventing other postoperative complications but not specifically respiratory ones. Applying sequential compression devices (SCDs) (choice D) is beneficial for preventing deep vein thrombosis but not directly related to respiratory complications.

3. When a client with schizophrenia who experiences auditory hallucinations says, 'It's hard not to listen to the voices,' which question should the nurse ask?

Correct answer: D

Rationale: The correct question for the nurse to ask the client who experiences auditory hallucinations and finds it hard not to listen to the voices is, 'What helps you ignore what you are hearing?' This question focuses on promoting coping strategies and therapeutic communication, encouraging the client to share what techniques or interventions have been effective for managing the auditory hallucinations. Choice A is incorrect because it assumes the client does not understand that the voices are not real, which may not be the case. Choice B delves into the reasons behind the voices, which may not be immediately helpful in managing the current situation. Choice C suggests a physical solution of going to a private place, which may not address the underlying issue of coping with the voices.

4. While caring for a client receiving an opioid analgesic for pain management, which assessment should the nurse prioritize?

Correct answer: D

Rationale: The correct answer is to monitor the client's respiratory rate. When a client is receiving opioids, the priority assessment is the respiratory rate since opioids can lead to respiratory depression. Monitoring urinary output, blood pressure, and constipation are also important but not the priority in this scenario.

5. A nurse is reviewing the medical record of a client who has hypothyroidism. Which of the following findings should the nurse expect?

Correct answer: A

Rationale: The correct answer is A. Weight gain can indicate myxedema, which is a symptom commonly seen in hypothyroidism. Exophthalmos (choice B) is actually a characteristic finding of hyperthyroidism, not hypothyroidism. Tachycardia (choice C) and heat intolerance (choice D) are also more indicative of hyperthyroidism rather than hypothyroidism.
