A nurse is caring for a client. Select the 5 findings that can cause delayed wound healing.

Prealbumin level.

History of diabetes mellitus.

History of hyperlipidemia.

Wound infection.

Decreased pedal perfusion.

Fasting blood glucose.

Answer and Explanation

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

Choice A rationale

Prealbumin level is an important indicator of nutritional status. Low prealbumin levels can indicate poor nutrition, which can delay wound healing. Adequate protein intake is essential for tissue repair and regeneration.

Choice B rationale

History of diabetes mellitus is a significant factor that can delay wound healing. Diabetes can impair blood flow and reduce the supply of oxygen and nutrients to the wound, leading to slower healing.

Choice C rationale

History of hyperlipidemia is not directly associated with delayed wound healing. While it can contribute to other health issues, it is not a primary factor in wound healing.

Choice D rationale

Wound infection is a major factor that can delay wound healing. Infections can cause inflammation, tissue damage, and increased exudate, all of which can impede the healing process.

Choice E rationale

Decreased pedal perfusion indicates poor blood flow to the lower extremities. Adequate blood flow is crucial for delivering oxygen and nutrients to the wound site, and decreased perfusion can significantly delay healing.

Choice F rationale

Fasting blood glucose levels are important in managing diabetes. High blood glucose levels can impair the immune response and reduce the body’s ability to heal wounds effectively.

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.

A. “Eating a high fiber diet will reduce my risk for developing skin cancer.”. B. “I should check my skin monthly for any changes.”. C. “I should avoid the use of tanning booths.”. D. “I should use sunscreen even on cloudy days.”. E. “I should use sunscreen even on cloudy days.”.

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.
