A client is scheduled to have a percutaneous transluminal coronary angioplasty (PTCA) to treat coronary artery disease. What information about the balloon-tipped catheter would the nurse plan to include when providing client education concerning the procedure?
Correct answer
C
Rationale
Correct Answer: C - The catheter will be used to compress the plaque against the coronary blood vessel wall.
Rationale: During a PTCA procedure, a balloon-tipped catheter is used to compress the plaque against the vessel wall, widening the artery lumen and improving blood flow. This process does not involve cutting away the plaque or taking pressure measurements. Option A is incorrect as the catheter does not spring open but rather compresses the plaque. Option B is incorrect as the catheter is not used for pressure measurements. Option D is incorrect as there is no embedded blade to cut away the plaque.
