Select the 5 findings that can cause delayed wound healing.

History of diabetes mellitus.

History of hyperlipidemia.

Wound infection.

Decreased pedal perfusion.

Fasting blood glucose.

Answer and Explanation

Correct Answer : A,B,C,D,E

Choice A rationale

A history of diabetes mellitus can cause delayed wound healing due to poor blood circulation and neuropathy, which can lead to reduced sensation and increased risk of infection.

Choice B rationale

A history of hyperlipidemia can contribute to delayed wound healing by causing atherosclerosis, which reduces blood flow to the wound site and impairs healing.

Choice C rationale

Wound infection is a direct cause of delayed wound healing. Infection can lead to increased inflammation, tissue damage, and prolonged healing time.

Choice D rationale

Decreased pedal perfusion indicates poor blood flow to the lower extremities, which can significantly delay wound healing by reducing the delivery of oxygen and nutrients to the wound.

Choice E rationale

Fasting blood glucose levels are important to monitor in patients with diabetes, as high glucose levels can impair the body’s ability to heal wounds effectively.

A. A mesh-like device within the catheter will be inflated causing it to spring open. B. The catheter will be positioned in a coronary artery to take pressure measurements in the vessel. C. The catheter will be used to compress the plaque against the coronary blood vessel wall. D. The catheter will cut away the plaque from the coronary vessel wall using an embedded blade.

Correct Answer is C

Explanation

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.
