A nurse is providing teaching to a client who has a new prescription for Warfarin. Which of the following statements by the client indicates a need for further teaching?

Correct Answer: C

Rationale: Rationale: Correct Answer: C) I will increase my intake of foods high in potassium. Explanation: This statement indicates a need for further teaching because Warfarin is a vitamin K antagonist, not potassium. Increasing potassium intake can potentially interfere with the anticoagulant effects of Warfarin, leading to ineffective treatment and increased risk of clotting. Option A: Avoiding large amounts of green leafy vegetables is correct because they are high in vitamin K, which can interfere with the effects of Warfarin. This statement shows the client understands the dietary restrictions necessary while on Warfarin therapy. Option B: Taking medication at the same time every day is important for maintaining consistent blood levels of Warfarin and ensuring its effectiveness. This statement demonstrates good medication adherence practice. Option D: Reporting any signs of bleeding to the provider is crucial when on Warfarin as it can increase the risk of bleeding. This statement indicates the client's understanding of a potential side effect and the importance of timely reporting to healthcare providers. Educational Context: Understanding the dietary restrictions, medication adherence, and potential side effects of Warfarin is essential for clients to manage their therapy effectively and prevent complications. Providing accurate and comprehensive education empowers clients to take an active role in their healthcare and promotes safe medication use.

Correct Answer: B

Rationale: In the context of pharmacology, the correct answer to the question is option B) Increase intake of foods high in potassium. When a client is prescribed Furosemide, which is a loop diuretic, there is an increased risk of hypokalemia (low potassium levels) due to the drug's mechanism of action of promoting potassium excretion in the urine. By instructing the client to increase intake of foods high in potassium, such as bananas, oranges, potatoes, and spinach, the nurse is helping to prevent or counteract the potential electrolyte imbalance caused by Furosemide. This is a crucial aspect of patient education to ensure the client's safety and therapeutic effectiveness of the medication. The other options are incorrect: A) Taking Furosemide at bedtime is not a specific instruction related to the medication's action or side effects. C) Avoiding sun exposure is not directly related to the use of Furosemide. D) Limiting fluid intake is not generally recommended with Furosemide unless specifically advised by the healthcare provider for certain medical conditions. Educationally, understanding the rationale behind specific medication instructions helps nurses provide comprehensive patient education, promote medication adherence, and prevent potential adverse effects. It also highlights the importance of tailoring patient education to the individual's medication regimen to optimize therapeutic outcomes.

Correct Answer: C

Rationale: The correct answer is C. A decrease in episodes of angina indicates that Aspirin is effectively preventing the formation of clots that could lead to cardiovascular events. Angina is chest pain or discomfort caused by reduced blood flow to the heart muscle, usually due to coronary artery disease. Aspirin works by inhibiting platelet aggregation, thereby reducing the risk of clot formation in the arteries. Improvement in angina symptoms suggests that the medication is successfully preventing clot-related complications in the cardiovascular system. Monitoring and recognizing a decrease in angina episodes can be a valuable indicator of the medication's efficacy in preventing cardiovascular events.

Correct Answer: C

Rationale: Severe pain around the eyes that radiates over the face is a classic symptom of acute angle-closure glaucoma. This intense pain is often associated with other symptoms such as blurred vision, halos around lights, redness in the eye, and sometimes nausea and vomiting. Immediate medical attention is required to prevent permanent vision loss.

Correct Answer: C

Rationale: Flumazenil is a competitive benzodiazepine antagonist that can reverse the sedative effects of benzodiazepines like Diazepam. In cases of oversedation, administering Flumazenil can help counteract the excessive sedation and other effects of Diazepam, thereby promoting the client's recovery and preventing potential complications.
