The client is receiving discharge instructions for warfarin (Coumadin). Which statement by the client indicates a need for further teaching?

Correct Answer: A

Rationale: The correct answer is A. Clients taking warfarin need to be consistent with their vitamin K intake to maintain a balance in blood clotting. Avoiding foods high in vitamin K is essential as they can interfere with the medication's effectiveness. Choices B, C, and D are all correct statements regarding warfarin therapy. Regular blood testing to monitor INR levels ensures the medication is working effectively, taking the medication at the same time daily maintains a consistent level in the bloodstream, and using a soft toothbrush helps prevent gum bleeding due to warfarin's anticoagulant effects.

Correct Answer: A

Rationale: The correct action to maintain patency of a nasogastric (NG) tube is to flush the tube with water before and after medication administration. Flushing helps prevent clogging and ensures that the tube remains clear for proper functioning. Securing the tube to the client's gown (Choice B) is important for stability but does not directly address tube patency. Checking the placement of the tube by auscultation (Choice C) is crucial for verifying correct placement but does not specifically relate to maintaining tube patency. Irrigating the tube with normal saline every shift (Choice D) is not a routine practice for maintaining tube patency and can lead to electrolyte imbalances.

Correct Answer: C

Rationale: Providing the client with washcloths to fold is a non-restrictive intervention that can help distract and engage the client, potentially reducing the need for restraints. This action promotes a therapeutic and calming environment for the confused client. Placing the client in a room away from the nurses' station (Choice A) may not address the underlying issue of confusion and agitation. Limiting the client's visitors (Choice B) may not directly assist in managing the client's behavior. Closing the door of the client's room (Choice D) does not actively engage the client in a therapeutic intervention to address the behavior.

Correct Answer: A

Rationale: Administering oxygen via a nasal cannula is the priority action for a client experiencing chest pain due to coronary artery disease. Oxygen therapy helps improve oxygenation, reduce myocardial workload, and relieve chest pain by increasing oxygen delivery to the heart muscle. While measuring vital signs, obtaining a 12-lead ECG, and encouraging pursed-lip breathing are important interventions, administering oxygen takes precedence in this situation to address the potential hypoxemia associated with chest pain in a client with a history of coronary artery disease.

Correct Answer: B

Rationale: When documenting client care, it is crucial to use standardized abbreviations to ensure clear communication and prevent misunderstandings. BRP for bathroom privileges is a recognized and commonly used abbreviation in healthcare settings. Choice A, SS for sliding scale, is not a standard abbreviation and can lead to confusion as it could be mistaken for other meanings. Choice C, OJ for orange juice, is informal and may not be universally understood in a healthcare context. Choice D, SQ for subcutaneous, is a valid abbreviation but may not be as relevant in the context of documenting client care compared to BRP, which is more specific and widely accepted.
