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 C
Explanation
Choice A rationale
Moist skin is not typically associated with cirrhosis. Cirrhosis often leads to dry, itchy skin due to bile salt accumulation under the skin.
Choice B rationale
Blood in the urine is not a common finding in cirrhosis. This symptom is more indicative of urinary tract issues or kidney problems.
Choice C rationale
Spider angiomas are a common finding in clients with cirrhosis. These are small, dilated blood vessels that appear close to the surface of the skin and are caused by increased estrogen levels due to liver dysfunction.
Choice D rationale
Tarry stools indicate gastrointestinal bleeding, which can occur in cirrhosis due to varices, but it is not a primary expected finding.
Correct Answer is A
Explanation
Choice A rationale
Eating a high fiber diet will reduce my risk for developing skin cancer. This statement is incorrect because a high fiber diet has not been proven to reduce the risk of developing skin cancer. Skin cancer is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning booths.
Choice B rationale
I should check my skin monthly for any changes. This statement is correct. Regular self- examinations can help detect skin cancer early when it is most treatable. The American Academy of Dermatology recommends checking your skin from head to toe every month.
Choice C rationale
I should avoid the use of tanning booths. This statement is correct. Tanning booths emit UV radiation, which increases the risk of developing skin cancer. Avoiding tanning booths is a crucial preventive measure.
Choice D rationale
I should use sunscreen even on cloudy days. This statement is correct. UV rays can penetrate clouds, so it is essential to use sunscreen every day, regardless of the weather, to protect the skin from harmful UV radiation.
