The nurse is providing discharge teaching to a client with a new prescription for warfarin (Coumadin). Which dietary instruction should the nurse include?

Correct Answer: A

Rationale: The correct dietary instruction for a client taking warfarin is to avoid foods high in vitamin K. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Consuming foods high in vitamin K, such as leafy green vegetables, can antagonize the effects of warfarin, potentially leading to treatment inefficacy or fluctuations in anticoagulation levels. Therefore, clients on warfarin therapy should be advised to avoid foods high in vitamin K to maintain the effectiveness of the medication. Choices B, C, and D are incorrect because increasing leafy green vegetables (choice B) would introduce more vitamin K, consuming a consistent amount of foods high in potassium (choice C) is not directly related to warfarin therapy, and limiting high-protein foods (choice D) is not a specific concern for clients on warfarin therapy.

Correct Answer: A

Rationale: In the presence of moderate, persistent, chronic neuropathic pain, the WHO pain relief ladder recommends continuing gabapentin, as it is effective for managing both anxiety and pain. Ibuprofen, a nonsteroidal anti-inflammatory drug, is not the mainstay for neuropathic pain relief according to the ladder and can be discontinued if needed. Aspirin is not typically added to the protocol for neuropathic pain management at this step. Methadone is reserved for severe pain and is not the standard choice at Step 2 of the WHO pain relief ladder for neuropathic pain.

Correct Answer: B

Rationale: Repositioning the client's arm is the initial action to take when encountering an obstruction with an antecubital saline lock. Repositioning may correct any bending at the elbow that could be causing the obstruction, allowing for smoother infusion flow. Checking for a blood return, removing the IV site dressing, or flushing the lock with saline would be subsequent actions once the obstruction is addressed. Checking for a blood return is done to confirm proper placement, removing the IV site dressing is necessary for site assessment, and flushing the lock with saline helps maintain patency but should not be the first action when an obstruction is detected.

Correct Answer: C

Rationale: It is essential for clients using herbal therapies to obtain herbs from manufacturers with a history of quality control for their supplements. This recommendation is crucial because quality control processes help in maintaining the purity and effectiveness of the herbal supplements. Option A is incorrect as it provides a negative and inaccurate generalization about herbs. Option B is also incorrect as there is existing evidence on the safety and efficacy of certain herbal supplements. Option D is not the most relevant information to offer initially to a client seeking advice on the general use of herbal supplements.

Correct Answer: D

Rationale: The best action for the nurse when assisting an older client who can stand but not ambulate from the bed to a chair is to use a transfer belt. Placing a transfer belt around the client, assisting the client to stand, and pivoting to a chair that is placed at a right angle to the bed allows for a safe and controlled transfer. This method promotes patient independence while ensuring safety during the transfer process. Choices A, B, and C are incorrect because using a mechanical lift may not be necessary for a client who can stand, using a roller board may not provide enough stability, and lifting the client with the help of another staff member may not be the safest option for the client's independence and safety.
