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.

Silvery, white scales are a characteristic finding in psoriasis. Psoriasis is a chronic autoimmune condition that causes rapid skin cell turnover, leading to the buildup of scales and red patches on the skin.
Choice B rationale
Intense pain is not typically associated with psoriasis. While psoriasis can cause discomfort and itching, it is not usually described as intensely painful.
Choice C rationale
Unilateral lesions are not characteristic of psoriasis. Psoriasis typically presents with symmetrical lesions on both sides of the body.
Choice D rationale
Serous drainage is not a common finding in psoriasis. Psoriasis lesions are usually dry and scaly rather than exudative. .

Explanation
Choice A rationale
Using friction when washing the affected area can irritate the skin and worsen acne. Gentle cleansing is recommended to avoid aggravating the condition.
Choice B rationale
Using a new cosmetic pad with each limited application of makeup helps prevent the spread of bacteria and reduces the risk of further clogging pores, which can exacerbate acne.
Choice C rationale
Using an oil-based soap can clog pores and worsen acne. Non-comedogenic, water-based cleansers are recommended for acne-prone skin.
Choice D rationale
Expressing larger comedones periodically can lead to skin damage and scarring. It is better to use appropriate acne treatments to manage comedones.
