A nurse is assessing a client with partial-thickness burns. Which cue indicates worsening of the condition?

Choice A rationale Mild pain that responds well to prescribed analgesics is a normal and expected finding in patients with partial-thickness burns. These burns involve the epidermis and varying depths of the dermis, leaving sensory nerve endings exposed and highly sensitive. If pain is manageable with standard care, it suggests that the inflammatory process is stable and not complicated by secondary issues. Effective pain control is a goal of care rather than a sign of clinical deterioration. Choice B rationale The presence of blisters, or bullae, is a defining characteristic of superficial partial-thickness burns. These occur as fluid collects between the epidermal and dermal layers due to increased capillary permeability after the thermal injury. While they require careful management to prevent rupture and infection, their presence is an expected clinical feature of this burn depth. Blisters alone do not signify that the wound is worsening; they are part of the initial injury presentation. Choice C rationale Increasing erythema and the presence of purulent drainage are classic signs of a localized bacterial infection, which indicates a worsening condition. In burn patients, the loss of the skin barrier makes the wound highly susceptible to pathogens. Purulent discharge consists of leukocytes, liquefied dead tissue, and cellular debris, signaling an active immune response to infection. If left untreated, this can progress to systemic sepsis, which is a leading cause of mortality in burn injuries. Choice D rationale A burn area that feels warm to the touch is often a result of the localized inflammatory response and increased blood flow to the injured site as the body begins the healing process. While excessive heat can sometimes be associated with infection, warmth is generally an expected finding in the early stages of a burn as the tissue remains hyperemic. By itself, warmth does not provide sufficient evidence of clinical worsening compared to the presence of purulent drainage.
