NCLEX-RN® Integumentary and Burns: Wound Care, Pressure Injuries, and Fluid Shifts

Skin and burn nursing for the NCLEX-RN®: pressure injury staging, wound care principles, burn percentage estimation, and fluid resuscitation priorities in major burns.

The big picture

The integumentary system — skin, hair, and nails — is the body's largest organ and its first line of defense against infection. NCLEX-RN® questions in this area test wound assessment, burn management, and pressure injury prevention and staging. The common thread is: identify the severity, prevent infection, and address fluid balance.

Wound assessment and wound care

Wound classification

Wound healing types

Normal wound healing progression

1. Hemostasis: Bleeding stops; clot forms (minutes to hours)
2. Inflammatory phase: Redness, swelling, warmth, pain — normal for 3–5 days
3. Proliferative phase: Granulation tissue fills the wound; re-epithelialization begins (days to weeks)
4. Remodeling phase: Scar matures and strengthens (months to years)

Signs of wound infection

Wound dehiscence and evisceration

• Dehiscence: Wound edges separate — risk increases with obesity, poor nutrition, infection, coughing/vomiting
• Evisceration: Bowel protrudes through the open wound — emergency

Action for evisceration:

1. Stay with the patient; call for help
2. Cover the protruding tissue with a sterile saline-soaked dressing — never push it back
3. Position: supine with knees bent (reduces tension on the wound)
4. Notify provider immediately — OR preparation will follow
5. Keep patient NPO

Pressure injuries (pressure ulcers)

Pressure injuries are localized tissue damage caused by sustained pressure, shear, or friction — typically over a bony prominence.

Risk factors

• Immobility (bedfast, wheelchair-bound)
• Incontinence (moisture maceration)
• Malnutrition (protein deficiency impairs healing)
• Impaired sensation (SCI, diabetes, neuropathy)
• Altered perfusion (diabetes, PVD, hypotension)
• Older age (thinner skin, reduced subcutaneous tissue)

Staging system (NPUAP/EPUAP 2019 consensus)

NCLEX® key: A pressure injury cannot be reverse-staged or "upgraded" as it heals. A healed Stage 4 is documented as "healed Stage 4," not re-classified as Stage 1 or 2.

Pressure injury prevention — the nursing priority

Prevention is always preferred and is a core nursing responsibility.

Wound care for pressure injuries

Burns

Burns are classified by cause (thermal, chemical, electrical, radiation) and depth.

Burn depth classification

NCLEX® key: Full-thickness burns are painless because nerve endings are destroyed. This is counterintuitive — the largest burns may hurt least in the center of the wound (but surrounding partial-thickness areas still hurt).

Rule of nines — estimating TBSA burned

Used to estimate total body surface area (TBSA) burned in adults:

Lund and Browder chart is used for children (proportions differ — head is larger, legs smaller).

The three phases of burn care

1. Emergent/resuscitative phase (first 24–48 hours)

The priority is airway and fluid resuscitation. Burns destroy the skin barrier — massive fluid shifts out of the vascular space into the interstitium (third-spacing).

Airway priority signs:

• Singed nasal hair or eyebrows
• Hoarseness, stridor, carbonaceous (black) sputum
• Burns to face, neck, or oropharynx
• Exposure to steam or smoke in an enclosed space

If airway compromise is suspected, intubate early — edema can close the airway within hours.

Fluid resuscitation (Parkland formula):

• 4 mL × body weight (kg) × % TBSA burned (second- and third-degree only)
• Give half in the first 8 hours from time of burn
• Give second half over the next 16 hours
• Fluid of choice: lactated Ringer's (LR) — most physiologically balanced
• Hourly urine output goal: 30–50 mL/hr in adults (monitor kidney perfusion)

2. Acute/wound care phase (days to weeks)

• Wound debridement and cleansing
• Dressing changes (hydrotherapy, silver-containing dressings)
• Escharotomy if circumferential full-thickness burns restrict circulation or respiration (performed by provider — nurse monitors neurovascular status and prepares the patient)
• High-protein, high-calorie diet — burn patients have extremely high metabolic needs; early enteral nutrition is started

3. Rehabilitation phase

• Scar management: pressure garments (worn 23 hours/day for 12–18 months)
• Range-of-motion exercises to prevent contracture
• Psychological support — disfigurement, PTSD, and depression are common

NCLEX® clinical judgment focus

For integumentary questions, the priority order:

1. Airway first in burns — inhalation injury is the leading cause of burn mortality
2. Fluid resuscitation — calculate and initiate in the first hour
3. Assess the wound — stage, measure, describe drainage
4. Prevent infection — burns are immunosuppressive; standard aseptic technique

Common NCLEX® traps:

• Staging a healed wound backward ("it healed, so it's Stage 2 now") — staging cannot be reversed
• Forgetting that full-thickness burns are painless
• Not checking for inhalation injury in a house-fire patient
• Giving only half the calculated fluid by the wrong time — first half in 8 hours from burn, not from hospital arrival

FAQ

Can you reverse-stage a pressure injury as it heals?

No. A pressure injury is staged at its worst point. As it heals, it fills in with granulation tissue (not normal skin layers in order), so it cannot be re-classified as a lower stage. Document it as "healing Stage 3" or "healed Stage 4," not "now Stage 2."

What is the Parkland formula and when is it applied?

The Parkland formula calculates fluid resuscitation volume for burn patients: 4 mL × kg × %TBSA burned. Half is given in the first 8 hours from the time of the burn (not time of hospital arrival), and the second half over the following 16 hours. Only second- and third-degree (partial and full-thickness) burns are counted in the TBSA calculation.

What makes an inhalation injury a priority over the visible burn?

Inhalation injury causes airway edema that can close the airway within hours — causing death faster than surface burns. Signs: singed nasal hairs, hoarseness, stridor, carbonaceous sputum, and a history of fire in an enclosed space. Early intubation is life-saving; once edema develops, intubation becomes impossible.

What is an escharotomy and when is it needed?

An escharotomy is an incision through full-thickness burn eschar to relieve pressure from circumferential burns. When a full-thickness burn encircles a limb, it can compress blood vessels (compartment syndrome) and prevent expansion of the chest wall for breathing. The nurse's role is to monitor neurovascular status and document circulation — the provider performs the procedure.

What is the most important dietary consideration for a burn patient?

Burns dramatically increase metabolic rate (by 50–100%). High-protein, high-calorie nutrition is essential for wound healing, immune function, and muscle preservation. Early enteral nutrition (within 6–12 hours of major burn) significantly improves outcomes and reduces infection risk.

Key takeaways

• Wounds: Healing phases: hemostasis → inflammation (normal 3–5 days) → proliferation → remodeling. Evisceration = cover with saline gauze, do not push back, call provider.
• Pressure injuries: Stage 1–4 + unstageable + deep tissue injury. Cannot reverse-stage. Prevent with repositioning every 2 hours, heel floats, moisture barriers, nutrition support.
• Burns: Classify by depth. Full-thickness = painless. Rule of nines for TBSA. Parkland formula: 4 mL × kg × %TBSA; first half in 8 hours from burn time. Airway first in inhalation injury.
