The nurse plans to assist a male client out of bed for the first time since his surgery yesterday. His wife objects and tells the nurse to get out of the room because her husband is too ill to get out of bed. What should the nurse do first?

Correct Answer: D

Rationale: Before assisting the client out of bed, the nurse should first assess the client's blood pressure and pulse. This assessment is crucial to determine the client's physiological stability and readiness for ambulation. It ensures the client's safety during the transfer and helps prevent any potential complications that may arise from getting out of bed. Administering oxygen, lying the client back down, or quickly moving the client to a chair without assessing vital signs can compromise the client's safety and may lead to adverse outcomes.

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: C

Rationale: In a client with a history of coronary artery disease (CAD) experiencing chest pain, the priority intervention for the nurse to implement first is to apply oxygen via nasal cannula. Oxygenation is crucial to ensure adequate oxygen supply to the tissues and the heart. This intervention takes precedence over administering sublingual nitroglycerin, obtaining an ECG, or initiating continuous cardiac monitoring. While these interventions are important, ensuring adequate oxygenation is the initial priority in the management of a client with chest pain.

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.
