Which statement by a client scheduled for a percutaneous transluminal coronary angioplasty indicates a need for further teaching?

The statement indicating a need for further teaching is the one expressing the belief that angina will be gone for good following the procedure. While percutaneous transluminal coronary angioplasty (PTCA) is an effective treatment for relieving symptoms of angina by widening narrowed arteries and improving blood flow to the heart, it does not guarantee that angina will not return in the future. Many factors, including the underlying coronary artery disease and lifestyle choices, can affect the recurrence of angina. Even after the intervention, patients might still experience episodes of angina, especially if they do not adhere to recommended lifestyle changes or if new blockages develop.

The other statements reflect accurate expectations regarding the procedure and its aftermath. Being awake during the procedure is standard, as local anesthesia is typically used. After the procedure, patients must lie still to prevent complications at the catheter insertion site, which is another correct understanding.
