Tissue Integrity and Wound Healing

These flashcards cover key concepts related to tissue integrity and wound healing, including types of healing, nursing interventions, factors influencing healing, and wound assessment techniques.

What are the three types of wound healing?

Primary healing, Secondary healing, Tertiary healing.

What is primary healing also known as?

First intention healing.

What is secondary healing also referred to as?

Second intention healing.

What characterizes tertiary healing?

A combination of primary and secondary healing where the wound is left open for 5 to 10 days before closure.

What is a key characteristic of secondary intention healing?

The wound is left open and granulation tissue forms from the bottom up.

What is the primary action to promote tissue integrity for high-risk clients?

Keep them clean, dry, and reposition frequently.

What are some interventions to minimize the risk of pressure injury?

Preventive dressings, supportive surfaces, hydration, and a mobilization plan.

How should clients be repositioned to relieve pressure points?

At regular intervals, considering their individualized needs and support surfaces.

What factors can influence wound healing?

Diabetes, infection, foreign objects, medications, malnutrition, tissue necrosis, and hypoxia.

How does diabetes affect wound healing?

Decreases peripheral perfusion and impairs sensation, slowing healing.

What role do foreign bodies in a wound play in healing?

Increase infection risk, delaying the healing process.

What nutritional needs are critical for wound healing?

Sufficient protein, calories, vitamins (A and C), and minerals (zinc).

What effect does hypoxia have on wound healing?

Decreases oxygen levels, which can impair healing due to vasoconstriction.

How is wound depth measured?

By inserting a sterile applicator under the wound edges until resistance is felt.

What is tunneling in wound assessment?

The development of a narrow channel or passageway extending from the base of the wound.

What is the primary cause of pressure injuries?

Prolonged pressure over an area of the skin combined with shearing forces.
