A nurse is discussing intravenous Amphotericin B treatment with a nursing student who is about to care for a patient with a systemic fungal infection. Which statement by the student indicates a need for further teaching?

Choice A reason:
As mentioned earlier, infusion reactions are common with Amphotericin B, including symptoms like fever and chills. Therefore, recognizing that these reactions occur is correct and indicates a proper understanding of the medication's effects.
Choice B reason:
Rapid administration of Amphotericin B is incorrect because it increases the risk of severe side effects. The infusion should be slow to ensure patient safety, indicating that the student needs further teaching on this point. Thus, this choice is incorrect and suggests a misunderstanding.
Choice C reason:
Frequent rotation of the IV site or the use of a central line is standard practice to minimize the risk of phlebitis. This practice is correct and shows that the student understands how to manage the complications associated with Amphotericin B infusion.
Choice D reason:
Amphotericin B's primary use is to treat systemic fungal infections. This is a correct statement, reflecting an accurate understanding of the drug's purpose and does not require further teaching.

Choice A reason:
Arterial emboli from a heart valve are not the most common cause of myocardial ischemia. While emboli can obstruct blood flow and cause ischemia, they are a less common cause compared to atherosclerosis. Embolic events typically result from conditions like atrial fibrillation or valvular heart disease but do not account for the majority of myocardial ischemia cases.

Choice B reason:
Atherosclerosis is the most common cause of myocardial ischemia. It involves the buildup of plaque within the coronary arteries, leading to reduced blood flow and oxygen supply to the heart muscle. This condition is a leading cause of coronary artery disease and is responsible for the majority of myocardial ischemia cases.

Choice C reason:
Idiopathic vasospasm, although a cause of myocardial ischemia, is not as common as atherosclerosis. Vasospasm refers to the sudden constriction of a coronary artery, which can reduce blood flow to the heart muscle. However, it accounts for a smaller percentage of ischemia cases compared to the widespread prevalence of atherosclerosis.

Choice D reason:
Venous emboli are typically associated with conditions such as deep vein thrombosis and pulmonary embolism, affecting the venous circulation rather than the coronary arteries. They do not commonly cause myocardial ischemia, which primarily involves the coronary arteries and arterial blockages.
