A pediatric patient is hospitalized with poison ivy dermatitis.
Which nursing assessment is critical to ensure the skin's protective functions are retained?

Choice A rationale

While capillary refill time is an indicator of peripheral perfusion and should be within 2 to 3 seconds, it is not the highest priority for burns involving the chest. Peripheral circulation is important for assessing fluid resuscitation status and cardiac output, but it does not address immediate threats to life. In the hierarchy of trauma assessment, circulation follows the stabilization of the airway and the adequacy of the patient's breathing and ventilation.

Choice B rationale

Burns covering the chest carry a significant risk for inhalation injury and compromised chest wall expansion. The nurse must prioritize lung sounds and respiratory effort to detect stridor, wheezing, or decreased breath sounds which indicate airway edema or smoke inhalation. Inhalation of hot gases can cause rapid swelling of the glottis and subglottic structures. Ensuring a patent airway and adequate gas exchange is the most critical intervention in the emergent phase of burn care.

Choice C rationale

Pain assessment using a standardized score is necessary for patient comfort and to guide analgesic administration, particularly for partial-thickness burns which are extremely painful due to exposed nerve endings. However, pain is considered a secondary assessment compared to the respiratory system. While uncontrolled pain can increase metabolic demand and heart rate, it is not immediately life-threatening. The nurse addresses pain only after ensuring that the patient's airway and breathing are fully stabilized.

Choice D rationale

Assessing skin color and moisture helps determine the depth and severity of the burn, which is essential for calculating fluid requirements and planning wound care. Partial-thickness burns typically appear red, blistered, and moist. While this data is important for the overall treatment plan, it remains a lower priority than assessing for respiratory distress. Skin assessments are part of the secondary survey performed after the primary ABC assessment has been thoroughly completed and managed.

Choice A rationale

A sunburn is the most common example of a first-degree, or superficial, burn. This type of injury only involves the epidermis, the outermost layer of the skin. It is characterized by redness, pain, and heat without the formation of blisters. The skin remains intact, and the injury typically heals within three to six days without scarring. This level of burn does not require intensive fluid resuscitation because the skin's barrier function is largely preserved.

Choice B rationale

Excessive scarring, such as keloids or hypertrophic scars, is a complication associated with deeper burns that involve the dermis, such as second-degree or third-degree burns. First-degree burns do not damage the deeper layers of the skin where collagen production is significantly disrupted, so they do not result in significant scarring. Scarring indicates that the injury reached the dermal layer, triggering a more complex inflammatory and proliferative healing response that is absent in superficial burns.

Choice C rationale

Blistering is the hallmark of a second-degree, or partial-thickness, burn. This occurs when the injury extends through the epidermis and into the underlying dermis, causing fluid to accumulate between the layers. First-degree burns are strictly limited to the epidermis and do not produce blisters. Because second-degree burns involve deeper tissue damage and fluid shifts, they are more painful and carry a higher risk of infection compared to the simple redness seen in a first-degree burn.

Choice D rationale

Blackened, charred, or leathery skin is indicative of a third-degree, or full-thickness, burn. In these injuries, the epidermis and the entire dermis are destroyed, and the damage may extend into the subcutaneous fat or muscle. These burns are often painless because the nerve endings have been destroyed. This is a severe medical emergency that is far more advanced than a first-degree burn, which only causes minor damage and maintains the sensory function of the skin.
