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 D
Explanation
Choice A: Increasing oral fluids may help with hydration, but it will not reduce skin flushing caused by lisinopril. Lisinopril is an angiotensin-converting enzyme (ACE. inhibitor that dilates blood vessels and lowers blood pressure. Flushing occurs due to increased blood flow to the skin.
Choice B: Nitroglycerin is a vasodilator that relaxes smooth muscle in blood vessels and reduces chest pain caused by angina. It is not indicated for skin flushing caused by lisinopril. Moreover, nitroglycerin can lower blood pressure further and cause hypotension, headache, dizziness, and fainting.
Choice C: Going to an emergency department is not necessary for skin flushing caused by lisinopril. Flushing is not a sign of an allergic reaction or anaphylaxis, which would require immediate medical attention. Flushing is also not a symptom of a heart attack or stroke, which would present with other signs such as chest pain, shortness of breath, arm numbness, or slurred speech.
Choice D: Reassuring the client that facial flushing is a common side effect of lisinopril is the best action for the nurse to take. Flushing is not harmful or dangerous, and it usually subsides within a few hours. The nurse should explain the mechanism of action of lisinopril and its benefits for lowering blood pressure and preventing angina. The nurse should also advise the client to monitor his blood pressure regularly and report any signs of hypotension, such as dizziness, lightheadedness, or fainting.
Correct Answer is B
Explanation
Choice A: Determining the need for urinary catheterization is not a task that the nurse should assign to the PN, as this requires clinical judgment and critical thinking, which are beyond the scope of practice of the PN. This is a distractor choice.
Choice B: Titrating oxygen to prescribed parameters is a task that the nurse can assign to the PN, as this involves following orders and protocols, which are within the scope of practice of the PN. Therefore, this is the correct choice.
Choice C: Receiving a postoperative client and conducting the assessment is not a task that the nurse should assign to the PN, as this requires initial assessment and data collection, which are the responsibility of the registered nurse. This is another distractor choice.
Choice D: Evaluating and updating plans of care for clients is not a task that the nurse should assign to the PN, as this requires nursing diagnosis and outcome identification, which are part of the nursing process that only the registered nurse can perform. This is another distractor choice.
