A client in the surgical recovery area asks the nurse to bring the largest possible dose of pain medication available. Which action should the nurse implement first?

Choice A rationale; Family history of mental illness is important information to consider when assessing the client's overall mental health history, but it is not directly related to the immediate safety and effectiveness of duloxetine.

Choice B rationale: Weight change in the last month is relevant to monitoring for side effects of duloxetine, but it is not as critical as assessing liver function, which directly impacts the metabolism of the medication.

Choice C rationale: When planning care for a client starting on duloxetine, it is most important for the nurse to obtain liver function laboratory results. Duloxetine is primarily metabolized in the liver, and it is important to assess the client's liver function before starting the medication to ensure that the liver can process the drug effectively and safely. Clients with impaired liver function may require dose adjustments or be at higher risk for adverse effects, so obtaining liver function test results is crucial for safe medication management.

Choice D rationale: Recent use of other antidepressants is essential to avoid potential drug interactions, but it is not the most critical piece of information compared to assessing liver function, which directly affects the client's ability to process duloxetine.

Choice A rationale: this is not an appropriate response because while it may reduce the intake of vitamin K, suddenly changing the client's diet drastically may not be necessary. It is essential for the healthcare provider to make any necessary adjustments to the medication based on the client's diet.

Choice B rationale: Warfarin is an anticoagulant medication that works by inhibiting the formation of blood clots. It interacts with vitamin K, which plays a crucial role in the blood clotting process. Leafy green vegetables are rich in vitamin K, and their consumption can affect the effectiveness of warfarin. The nurse should advise the client to inform her healthcare provider about her vegetarian diet and the regular consumption of leafy green vegetables. The healthcare provider will then be able to adjust the warfarin dosage accordingly to ensure that the client receives the appropriate and consistent level of anticoagulation.

Choice C rationale: while a vegetarian diet can be healthy, the specific concern here is the potential impact of vitamin K-rich foods on warfarin therapy. It's essential to address this potential interaction rather than focusing solely on the overall healthy lifestyle.

Choice D rationale: Consuming large amounts of leafy green vegetables and vitamin K-rich foods may actually reduce the effectiveness of warfarin, leading to a decreased ability to prevent blood clots. Therefore, it is crucial to consult with the healthcare provider to manage the dosage appropriately.
