Burns nursing care: what to assess and what to do first
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
Burns nursing care prioritises airway first whenever there is facial or inhalation involvement, since airway swelling can close off within hours even without visible distress at first. Fluid resuscitation follows using the Parkland formula, with half the calculated volume given in the first eight hours from the time of injury, not from arrival.
The pathophysiology in one pass
A burn injury destroys the skin's barrier function and triggers a massive inflammatory response. Capillaries throughout the body become more permeable, not just at the burn site, allowing fluid and protein to leak into interstitial tissue. This is why large burns cause whole-body oedema and intravascular volume loss severe enough to cause hypovolemic shock, sometimes called burn shock, within the first 24 to 48 hours.
The depth of the burn determines the clinical picture. Superficial partial-thickness burns are painful because nerve endings remain intact; full-thickness burns can be painless at the centre because those nerve endings are destroyed, even as the surrounding partial-thickness zone is exquisitely tender. Circumferential full-thickness burns to a limb or the chest can also physically restrict circulation or breathing as tissue swells against unyielding eschar, a distinct mechanical problem from the fluid shifts happening elsewhere.
Assessment findings that matter
Any burn involving the face, singed nasal hair, soot around the mouth or nose, or a history of being burned in an enclosed space demands an immediate airway assessment, regardless of how the patient sounds right now. Inhalation injury and airway oedema can develop progressively over hours, so a patient talking normally on arrival can lose their airway later; hoarseness, stridor, or a brassy cough are late warning signs, not early ones.
Estimate total body surface area burned using the rule of nines or a Lund and Browder chart for children, since this figure drives fluid calculations. Assess burn depth, circulation distal to any circumferential burn, and check for carbon monoxide exposure, which presents as a normal pulse oximetry reading despite cellular hypoxia because standard pulse oximetry cannot distinguish carboxyhaemoglobin from oxyhaemoglobin. Cherry-red skin, a classic teaching point for carbon monoxide poisoning, is actually uncommon in practice, so do not rely on it.
What the exam asks about this
Expect priority-setting questions that test whether you choose airway management over starting fluids when both seem urgent, particularly for a patient with facial burns and a hoarse voice. The exam wants airway assessed and secured before or alongside fluid resuscitation, not after.
You should also expect Parkland formula calculation questions: total body surface area percentage multiplied by weight in kilograms multiplied by 4 mL, with half given in the first eight hours from the time of injury and the remaining half over the next sixteen hours. Questions frequently test whether the eight-hour clock starts at the time of injury or at hospital arrival; it starts at the time of injury, so a patient arriving three hours after being burned only has five hours left in that first window.
Nursing interventions in priority order
Airway comes first whenever facial burns, singed hair, or a history of enclosed-space exposure exist; anticipate early intubation before oedema makes it difficult, rather than waiting for stridor to appear. Administer high-flow oxygen and consider carbon monoxide poisoning even with a normal oxygen saturation reading.
Once airway is addressed, establish large-bore IV access, ideally through unburned skin, and begin fluid resuscitation using the Parkland formula with lactated Ringer's solution. Cover burns with clean, dry dressings and avoid ice or cold water on large burns, since this worsens hypothermia. Remove jewellery and constricting items before swelling progresses, assess circulation distal to circumferential burns hourly, and insert a urinary catheter to monitor hourly output as the most direct measure of resuscitation adequacy.
Medications and monitoring
Pain management needs to be aggressive and proactive, typically IV opioids, since burn pain is severe and undertreatment is common; intramuscular routes are avoided because impaired perfusion makes absorption unreliable. Tetanus prophylaxis is given if the patient's immunisation status is unclear or outdated.
Monitor hourly urine output as the primary indicator that fluid resuscitation is adequate, targeting roughly 0.5 mL/kg/hr in adults and higher in children. Watch for signs of under-resuscitation, such as falling urine output and rising heart rate, and over-resuscitation, such as worsening oedema and respiratory compromise, since both are risks with large-volume fluid therapy. Topical antimicrobial agents such as silver sulfadiazine may be applied per protocol, and daily weights help track fluid balance over the following days.
When to escalate
Escalate immediately if there is any sign of airway compromise: stridor, hoarseness, drooling, or difficulty swallowing. These signs mean intervention is needed now, not after further observation, because airway oedema in burns can progress from manageable to unmanageable within a single shift.
Also escalate for urine output persistently below target despite fluid adjustment, a compartment syndrome picture in a circumferential limb burn with diminishing pulses or worsening pain, or any burn covering more than 20 percent of body surface area in an adult, which typically requires transfer to a specialised burns unit. Chemical or electrical burns warrant early specialist involvement regardless of visible size, since internal tissue damage can far exceed what the surface appearance suggests.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our med-surg practice questions are the closest set to what this page covers.
One question from the med-surg set
A client with chronic obstructive pulmonary disease has an oxygen saturation of 88% on 2 L/min via nasal cannula and is alert with no distress. What should the nurse do first?
Rationale
In COPD a saturation of 88–92% is the therapeutic target, not an emergency, and this client is alert with no distress. The first action is the independent nursing intervention that is least invasive and most likely to help: sit them up and reassess. Turning the oxygen up to 6 L/min risks blunting the hypoxic drive, and calling rapid response or drawing an ABG escalates ahead of an assessment you have not finished.
Answer: B
Common questions
When does the Parkland formula clock start?
It starts at the time of injury, not at hospital arrival or when treatment begins. If a patient arrives several hours after being burned, that time is subtracted from the first eight-hour window, which changes the infusion rate needed to deliver the correct volume in the time remaining.
Why prioritise airway over fluids in a burns patient?
Airway oedema from facial or inhalation burns can progress silently over hours and become impossible to intubate once fully swollen, whereas fluid resuscitation, while urgent, allows a slightly wider treatment window. A patient who looks fine on arrival can lose their airway later if it is not addressed proactively.
Why is pulse oximetry unreliable in burns with smoke inhalation?
Standard pulse oximetry cannot distinguish oxyhaemoglobin from carboxyhaemoglobin, so a patient with significant carbon monoxide poisoning can show a normal or near-normal oxygen saturation reading while actually hypoxic at the cellular level. Suspect this in any burn from an enclosed-space fire and treat clinically, not by the pulse oximeter alone.
What is the priority nursing assessment for a circumferential limb burn?
Assess circulation distal to the burn hourly, checking pulses, capillary refill, sensation, and pain level, since swelling against unyielding eschar can cut off circulation like a tourniquet. Escalate immediately for diminishing pulses or worsening pain, as an escharotomy may be needed.
How is fluid resuscitation calculated in a burns patient?
The Parkland formula gives total body surface area percentage burned multiplied by weight in kilograms multiplied by 4 mL of lactated Ringer's solution, with half of that total infused in the first eight hours from injury and the rest over the following sixteen hours.
