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?
A mesh-like device within the catheter will be inflated causing it to spring open.
The catheter will be positioned in a coronary artery to take pressure measurements in the vessel.
The catheter will be used to compress the plaque against the coronary blood vessel wall.
The catheter will cut away the plaque from the coronary vessel wall using an embedded blade.
The Correct Answer is C
Choice A rationale
A mesh-like device within the catheter that springs open is characteristic of a stent, not a balloon-tipped catheter used in PTCA. Stents are often used in conjunction with angioplasty to keep the artery open after the balloon has compressed the plaque.
Choice B rationale
While catheters can be used to take pressure measurements, this is not the primary function of the balloon-tipped catheter in PTCA. The main purpose of the balloon-tipped catheter is to compress the plaque against the artery wall to improve blood flow.
Choice C rationale
The balloon-tipped catheter in PTCA is used to compress the plaque against the coronary blood vessel wall. This process, known as balloon angioplasty, helps to widen the artery and improve blood flow to the heart.
Choice D rationale
Cutting away plaque with an embedded blade is a description of atherectomy, not PTCA. Atherectomy involves a different type of catheter designed to remove plaque from the artery wall.

Correct Answer is A
Explanation
Choice A rationale
The weights from the traction device should only be removed if the client develops a life- threatening situation. This is to ensure the client’s immediate safety and address the critical condition.
Choice B rationale
The client should not have the weights removed for repositioning in the bed. Proper techniques should be used to reposition the client without removing the weights to maintain the effectiveness of the traction.
Choice C rationale
Complaints of pain should be addressed by assessing the cause and providing appropriate pain management, but the weights should not be removed as it can compromise the traction.
Choice D rationale
The weights should not be removed for an x-ray. The traction can be maintained during imaging procedures to ensure continuous treatment.
Correct Answer is C
Explanation
Choice A rationale
Flank pain with radiation to the groin and hematuria are more indicative of kidney issues, not heart failure.
Choice B rationale
Respiratory distress, chest pain, and use of accessory muscles can indicate respiratory issues but are not specific to heart failure.
Choice C rationale
Crackles, peripheral edema, and weight gain are classic signs of heart failure. These symptoms indicate fluid overload and poor cardiac function.
Choice D rationale
Confusion, decreasing level of consciousness, and aphasia are neurological symptoms and not specific to heart failure.
