A client is being discharged with a prescription for warfarin. Which instruction should the nurse provide this client regarding diet?
Increase the intake of dark green leafy vegetables while taking warfarin.
Eat two servings of dark green leafy vegetables daily and continue for 30 days after warfarin therapy is completed.
Eat approximately the same amount of leafy green vegetables daily so the amount of vitamin K consumed is consistent.
Avoid eating any foods that contain any vitamin K because it is an antagonist of warfarin.
The Correct Answer is C
Choice A reason: Increasing the intake of dark green leafy vegetables while taking warfarin is not a good instruction because it can decrease the effectiveness of warfarin. Dark green leafy vegetables are rich in vitamin K, which is a coagulation factor that counteracts the anticoagulant effect of warfarin.
Choice B reason: Eating two servings of dark green leafy vegetables daily and continuing for 30 days after warfarin therapy is completed is not a good instruction because it can cause bleeding complications. Dark green leafy vegetables are rich in vitamin K, which is a coagulation factor that counteracts the anticoagulant effect of warfarin. Stopping warfarin while continuing to eat high amounts of vitamin K can increase the risk of clot formation and thromboembolism.
Choice D reason: Avoiding eating any foods that contain any vitamin K because it is an antagonist of warfarin is not a good instruction because it can cause bleeding complications. Dark green leafy vegetables are rich in vitamin K, which is a coagulation factor that counteracts the anticoagulant effect of warfarin. Eliminating vitamin K from the diet can increase the sensitivity to warfarin and cause excessive bleeding and bruising.

Correct Answer is ["A","B","C","D"]
Explanation
The correct answer is A, B, C, and D.
Choice A reason: Flushing the gastrostomy tube with water is essential to maintain tube patency and prevent medication interactions. It should be done before and after medication administration. The typical amount of water used for flushing can range from 15 to 30 mL.
Choice B reason: Administering each medication separately is a critical practice to prevent drug interactions and ensure that the full dose of each medication is delivered. It also helps in preventing the clogging of the tube.
Choice C reason: Documenting all liquid volumes, including medications and water used for flushing, is important for accurate fluid intake records. This helps in maintaining fluid balance and monitoring the patient’s hydration status.
Choice D reason: Checking gastric residual volume is important to assess the patient’s tolerance to enteral feeding and to prevent complications such as aspiration. Normal gastric residual volumes are generally considered to be less than 250 mL.
Choice E reason: Using a plunger to administer medications through a gastrostomy tube is not always recommended. Medications should be administered slowly to prevent discomfort or harm, and the use of a plunger is not a standard practice across all healthcare settings.
Correct Answer is A
Explanation
Choice B reason: Forcing oral fluids and providing frequent small meals are not the most important interventions for a client with alcohol withdrawal delirium. Although hydration and nutrition are important to prevent dehydration and electrolyte imbalance, they are not the priority in this case. The client may have difficulty swallowing, vomiting, or aspiration due to altered mental status.
Choice C reason: Confronting the client's denial of substance abuse is not an appropriate intervention for a client with alcohol withdrawal delirium. The client may not be able to comprehend or respond rationally to such confrontation due to impaired cognition and perception. The nurse should avoid arguing or challenging the client's beliefs and focus on providing safety and comfort.
Choice D reason: Encouraging attendance and group participation is not a feasible intervention for a client with alcohol withdrawal delirium. The client may not be able to participate in any social or educational activities due to severe withdrawal symptoms and delusions. The nurse should limit visitors and stimuli and provide one-to-one supervision and reassurance.
