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 has a new prescription for alendronate. Which of the following instructions should the nurse include?

Correct answer: C

Rationale: The correct instruction when taking alendronate is to remain upright for 30 minutes after administration. This helps prevent esophageal irritation, a known side effect of the medication. Option A is incorrect because alendronate should be taken in the morning on an empty stomach. Option B is incorrect as taking alendronate with food decreases its absorption. Option D is incorrect as alendronate should be swallowed whole with a full glass of water and not chewed.

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

Correct answer: D

Rationale: The correct answer is D, INR. The International Normalized Ratio (INR) is used to monitor the therapeutic effect of warfarin and to adjust the dose as needed. While Prothrombin time (PT) and activated Partial Thromboplastin Time (aPTT) are also related to coagulation studies, monitoring INR specifically helps in managing warfarin therapy. Hemoglobin, on the other hand, is not typically monitored in relation to warfarin therapy.

4. A healthcare professional is preparing to administer an IV bolus of morphine to a client. Which of the following actions should the healthcare professional take first?

Correct answer: A

Rationale: Correct Answer: Checking the client's respiratory rate is the priority before administering morphine because morphine can depress respiration. This action helps the healthcare professional assess the client's baseline respiratory status and detect any potential respiratory depression that may be exacerbated by morphine. Choice B, administering naloxone, is incorrect because naloxone is used as an antidote for opioid overdose and not routinely administered before giving morphine. Choice C, checking the client's pain level, is important but not the first action to take before administering morphine. Choice D, assessing the client's blood pressure, is also important but not the initial priority compared to evaluating respiratory status when preparing to administer morphine.

5. A client who has a new prescription for lithium is receiving discharge teaching from a nurse. Which of the following client statements indicates an understanding of the teaching?

Correct answer: A

Rationale: The correct answer is A. Clients prescribed lithium need regular monitoring of blood levels to ensure the medication's effectiveness and safety. This monitoring helps to keep the medication within the therapeutic range and prevent toxicity. Choice B is incorrect because lithium is usually taken with food to minimize gastrointestinal side effects. Choice C is not directly related to lithium therapy; however, excessive sodium intake can affect lithium levels. Choice D is incorrect as abruptly stopping lithium can lead to adverse effects and should only be done under healthcare provider guidance.
