Describe the importance of dressing selection.
The right dressing protects from infection and maintains a moist environment. - Types: Hydrocolloid, foam, alginate - Match to wound type
Question: How often should a wound be assessed?
Wounds should be assessed at every dressing change or at least once daily. - Adjust care based on changes.
What is the role of moisture in wound healing?
Moisture aids healing by preventing crusting and allowing cells to migrate. - Reduces pain - Enhances granulation tissue formation

Types of Wounds(20)
Acute Wound
A wound that occurs suddenly and is expected to heal within a short time, usually by primary intention.
Chronic Wound
A wound that does not heal properly or takes longer than expected; often associated with underlying conditions.
Contusion
A bruise caused by blunt force trauma, resulting in bleeding under the skin without a break.
Laceration
A tear or a cut in the skin, often irregular in shape; may be deep and affect underlying tissues.
Abrasions
Superficial wounds caused by friction, affecting only the outer layer of skin, usually heal quickly.
Puncture Wound
A small but deep hole caused by a sharp object; risk of infection is high.
Surgical Wound
A wound created intentionally during a surgical procedure, typically designed to heal cleanly.
Pressure Ulcer
A localized injury to the skin and/or underlying tissue due to pressure, often over bony areas.
Burns
Injuries caused by heat, chemicals, electricity, or radiation; classified as first, second, or third degree.
Friction Wound
A type of abrasion caused by skin rubbing against a rough surface, often seen in bedridden patients.
Assessment of Wound Depth
Wounds can be classified by depth: superficial, partial thickness, and full thickness.
Penetrating Wound
A wound that breaks the skin and enters a body cavity, such as a gunshot or stab wound.
Full Thickness Wound
A wound that extends through the dermis to deeper tissues, requiring more complex healing.
Superficial Wound
A wound that affects only the epidermis, usually heals without scarring.
Partial Thickness Wound
Involves the epidermis and part of the dermis; may result in scarring.
Stage I Pressure Injury
Non-blanchable redness of intact skin; may indicate potential skin damage.
Stage II Pressure Injury
Partial thickness loss of skin; presents as a shallow open ulcer or blister.
Stage III Pressure Injury
Full thickness loss of skin; adipose tissue may be visible, may include tunneling.
Stage IV Pressure Injury
Full thickness tissue loss with exposed bone, tendon, or muscle; often has necrotic tissue.
Deep Tissue Injury
Persistent non-blanchable deep red, maroon, or purple discoloration; tissue may be damaged underneath.
Pressure Injuries(20)
What are pressure injuries?
Localized damage to the skin and underlying tissue, typically over a bony prominence, resulting from prolonged pressure.

What does the term 'shearing' refer to?
When skin moves in one direction while the underlying tissue remains stationary, causing injury.
Stage IV injury: key features?
Full-thickness loss, exposed bone, tendon, or muscle, often with tunneling.
What is the role of moisture in pressure injuries?
Excess moisture can lead to skin breakdown and increase the risk of injury.
