Ask the nurse to explain the type of angina he is experiencing.
The nurse explains the pain is due to the imbalance of myocardial supply.
Unstable.
Ischemic.
Stable angina.
Prinzmetal.
The Correct Answer is C
Choice A rationale
Unstable angina is characterized by sudden, severe chest pain that occurs at rest or with minimal exertion and is not relieved by nitroglycerin. It represents an imminent risk of myocardial infarction.
Choice B rationale
Ischemic heart disease can cause various types of angina, including stable, unstable, and Prinzmetal’s angina. The term “ischemic” refers to a lack of blood flow to the heart muscle, but this choice is too broad.
Choice C rationale
Stable angina occurs when there is an imbalance between myocardial oxygen supply and demand, typically during physical exertion or emotional stress. It is characterized by predictable chest pain that is relieved by rest or nitroglycerin.
Choice D rationale
Prinzmetal’s angina, also known as variant angina, is caused by a spasm in the coronary arteries, which leads to a temporary reduction in blood flow. It can occur at rest and is not necessarily related to the imbalance of myocardial supply and demand.

Correct Answer is D
Explanation
Choice A rationale
Vitamin E is an antioxidant and is not indicated to counteract the effects of warfarin. It does not have a role in reversing anticoagulation or managing bleeding. High doses of Vitamin E can actually interfere with clotting and potentially exacerbate bleeding.
Choice B rationale
Protamine Sulfate is an antidote for heparin, not warfarin. It works by neutralizing the effects of heparin, which is an anticoagulant that acts quickly to prevent clot formation. Warfarin works differently and requires a different antidote for its anticoagulant effect.
Choice C rationale
Calcium Gluconate is not an antidote for warfarin. It is typically used in cases of hypocalcemia and can stabilize cardiac membranes in hyperkalemia but has no effect on reversing warfarin-induced anticoagulation or bleeding.
Choice D rationale
Vitamin K is the correct antidote for warfarin. It counteracts the anticoagulant effects by promoting the synthesis of clotting factors that warfarin inhibits. Administering Vitamin K is standard practice in reversing the effects of warfarin and managing bleeding complications.
Correct Answer is D
Explanation
Choice A rationale
Anticonvulsant medications are not taken on an as-needed basis. They require consistent dosing to maintain therapeutic levels and prevent seizure activity effectively.
Choice B rationale
The goal of anticonvulsant therapy is not just temporary seizure control but long-term management. Medications are continued even after achieving seizure-free status to prevent recurrence.
Choice C rationale
While some patients might achieve control within a few years, there is no standard duration for stopping anticonvulsants. Treatment duration varies based on individual response and risk of recurrence.
Choice D rationale
Anticonvulsant medications are typically taken for a lifetime to manage epilepsy. Long-term therapy is crucial for maintaining seizure control and preventing breakthrough seizures.
