You are assisting a RN with discharging a patient who had a permanent pacemaker placed two days ago for sustained bradycardia. You are reinforcing the discharge teaching, what statement by the client indicates a need for further teaching?

A. Troponin levels will always be elevated: Troponin is a biomarker for myocardial necrosis and cell death, which does not occur in stable angina. In stable angina, the ischemia is transient and reversible, meaning cardiac enzymes typically remain within normal limits. Elevated troponin levels are diagnostic of an acute myocardial infarction rather than angina.

B. The pain is sharp and last for hours, usually radiating down the left leg: Anginal pain is characteristically described as a dull, crushing, or squeezing pressure in the substernal region. It typically lasts only a few minutes and may radiate to the left arm, neck, or jaw, but not the leg. Prolonged pain lasting for hours suggests a more serious acute coronary syndrome.

C. The pain is predictable with exertion and is relieved by rest or nitroglycerin: Stable angina follows a consistent pattern where chest discomfort is triggered by specific levels of physical activity or emotional stress. The increased myocardial demand is eased once the activity stops or when nitroglycerin causes coronary vasodilation. This predictability is the defining feature that differentiates it from unstable angina.

D. Pain occurs at rest and is relieved by nitroglycerin: Pain that occurs without exertion or while the patient is resting is classified as unstable angina or Prinzmetal's angina. This represents a more dangerous clinical state where blood flow is compromised even at baseline. Stable angina requires an external stressor to trigger the imbalance in oxygen supply.

A. Peripheral vascular disease: Intermittent claudication, or pain that occurs during ambulation and is relieved by rest, is a hallmark of arterial insufficiency. Mottling and hairlessness are objective signs of chronic tissue ischemia due to reduced peripheral blood flow. These findings indicate that the arterial supply is failing to meet the metabolic demands of the lower extremity.

B. Coronary artery disease: This condition involves the narrowing of the arteries supplying the heart muscle, typically presenting as chest pain or angina. While it shares the same underlying atherosclerotic process as peripheral vascular disease, it does not directly cause leg mottling or hairlessness. The client’s specific symptoms are localized to the peripheral rather than the cardiac circulation.

C. Right sided heart failure: Right-sided failure primarily manifests as systemic venous congestion, leading to jugular venous distention and dependent edema. It does not typically cause intermittent claudication or the skin changes associated with arterial deprivation. While it affects the lower extremities, it presents with swelling rather than mottling and hair loss.

D. Arterial embolism: An acute embolism usually presents with the "six Ps," including sudden, severe pain, pulselessness, and pallor. The client's report of intermittent pain relieved by rest suggests a chronic, progressive narrowing rather than an acute, total occlusion. An embolism is an emergency that would not typically be relieved simply by resting.
