A client with a history of deep vein thrombosis (DVT) is admitted with swelling and pain in the left leg. What is the most appropriate action for the LPN/LVN to take?

Correct Answer: C

Rationale: Measuring the circumference of the left leg is the most appropriate action for an LPN/LVN when assessing a client with a history of DVT and presenting with swelling and pain in the left leg. This measurement helps to assess the extent of swelling objectively and monitor changes in the client's condition. Applying warm compresses (Choice A) may worsen the condition by potentially promoting clot development. Elevating the left leg above the level of the heart (Choice B) is generally recommended for DVT to improve venous return, but measuring the circumference is more appropriate in this scenario. Administering pain medication (Choice D) does not address the underlying issue and should not be the initial action taken.

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: C

Rationale: The abdomen is the most appropriate site for administering subcutaneous heparin injections. The abdomen has a layer of subcutaneous fat and a good blood supply, making it an ideal site for subcutaneous injections. Using the deltoid muscle for heparin injections is not appropriate as it is typically used for intramuscular injections. The ventrogluteal site is more suitable for intramuscular injections rather than subcutaneous injections. The dorsogluteal site is no longer recommended for injections due to the risk of injury to the sciatic nerve.

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.
