The nurse correctly tells the client and family member how angioplasty with stenting is utilized to treat angina by using which explanation?

A. "A tiny balloon is used to open up the blocked artery and a wire mesh stent is placed to keep the artery open.": Percutaneous transluminal coronary angioplasty involves inflating a balloon to compress atherosclerotic plaque against the arterial wall. The subsequent placement of a stent provides structural support to prevent the vessel from recoiling or reclosing. This accurately describes the mechanical process of restoring coronary blood flow. B. "The blocked artery is bypassed to an areas where there is proper blood flow for the heart muscle.": This explanation describes a coronary artery bypass graft (CABG), which is a surgical procedure, not an angioplasty. Bypassing involves using a graft vessel to create a new route for blood flow around an obstruction. Angioplasty is a minimally invasive catheter-based intervention that works within the original vessel. C. "A tiny blade is used to cut away the plaque buildup and a stent is placed to keep the blood flowing properly.": The use of a cutting device to remove plaque is known as an atherectomy, which is a different procedure from standard angioplasty. While sometimes used together, angioplasty primarily relies on pressure and displacement rather than excision. Atherectomy is reserved for specific types of calcified or hard lesions. D. "The blood clot or plaque is dissolved, allowing for adequate blood flow and oxygen to flow to the heart muscle.": This describes thrombolytic therapy or fibrinolysis, which uses medications to chemically break down clots. Angioplasty is a mechanical intervention rather than a pharmacological one. While medications are used during the procedure, the primary mechanism of opening the vessel is physical dilation.
