Burns and Wound Care

What this lesson teaches

Burns and wounds are not just skin problems. The skin protects against infection, helps control temperature, and prevents fluid loss. When skin is damaged, the body can lose heat, fluid, and its protective barrier.

This lesson teaches common wound and burn terms in a student-friendly way.

• Compare superficial, partial-thickness, and full-thickness burns.
• Recognize wound infection warning terms.
• Understand basic dressing vocabulary and pressure injury staging.
• Explain why circulation, sensation, and infection checks matter.

Core lesson

A wound is a break or injury in tissue. A burn is tissue damage caused by heat, chemicals, electricity, radiation, or friction. The seriousness depends on depth, size, location, patient age, cause, and associated injuries.

Burn depth matters. Superficial burns affect the outer skin and are often red and painful. Partial-thickness burns involve deeper layers and may blister. Full-thickness burns destroy deeper skin layers and may appear waxy, leathery, white, brown, or charred. Full-thickness burns can sometimes hurt less in the center because nerves are damaged.

Wound care focuses on protection, moisture balance, infection prevention, and healing. Students should learn to describe drainage, odor, redness, swelling, warmth, pain, and tissue appearance.

Pressure injuries occur when pressure reduces blood flow to tissue, often over bony areas. Staging helps describe severity, from non-blanchable redness to deep tissue loss.

Key terms to know

Superficial burn

A burn affecting the outer layer of skin, often red, painful, and dry.

Partial-thickness burn

A burn involving deeper skin layers; blisters and moist tissue may appear.

Full-thickness burn

A severe burn destroying the full thickness of skin and possibly deeper tissues.

Eschar

Thick dead tissue that can form over a burn or wound.

Debridement

Removal of dead or contaminated tissue to support healing.

Exudate

Fluid drainage from a wound. It may be clear, bloody, or pus-like depending on the situation.

Purulent drainage

Thick pus-like drainage that can suggest infection.

Granulation tissue

New healing tissue, often pink or red and moist.

Pressure injury

Tissue injury caused by prolonged pressure, often over bony areas.

Non-blanchable redness

Redness that does not turn white when pressed; a warning sign for early pressure injury.

How to think through questions

• For wound questions, describe before you judge: color, size, depth, drainage, odor, surrounding skin, pain, and temperature.
• For burns, depth and percentage matter, but location matters too. Burns to face, hands, feet, genitals, major joints, or airway are higher concern.
• Infection clues include increasing redness, warmth, swelling, pain, pus-like drainage, odor, fever, or worsening wound appearance.

Common mistakes

• Assuming a less painful burn is less serious. Deep burns may damage nerves.
• Ignoring wound odor or changing drainage.
• Forgetting that pressure injury prevention includes turning, nutrition, moisture control, and support surfaces.
• Using vague wound language instead of describing what is seen.

Memory hooks

• Red and painful can be superficial; blisters suggest partial thickness; leathery or charred suggests deeper injury.
• Wound checks: color, drainage, odor, edges, surrounding skin.
• Pressure plus time equals tissue risk.
