A nurse is caring for a patient diagnosed with Stevens-Johnson syndrome (SJS). Which nursing intervention should be the highest priority?

Stevens-Johnson syndrome causes massive fluid and electrolyte loss from skin sloughing, making monitoring fluid and electrolyte balance the highest priority to prevent hypovolemic shock. Other interventions like topical antibiotics, oral hygiene, or positioning are important but secondary to maintaining hemodynamic stability.

Clinical Context and Priority Setting

Stevens-Johnson syndrome (SJS) is a rare, life-threatening mucocutaneous hypersensitivity reaction characterized by widespread epidermal necrosis and detachment. The condition carries a high mortality rate, largely driven by complications such as sepsis, fluid and electrolyte imbalances, and multi-organ failure. In the acute phase, massive fluid loss occurs through denuded skin, similar to the pathophysiology seen in extensive burn injuries. This loss is not merely water; it includes critical electrolytes and proteins, leading rapidly to hypovolemic shock, acute kidney injury, and metabolic instability if not aggressively managed.

When prioritizing nursing interventions for a patient with SJS, the airway, breathing, and circulation (ABC) framework must be applied. While airway and breathing assessments are critical due to potential respiratory tract involvement, the circulatory component—specifically fluid and electrolyte balance—becomes a central nursing focus once airway patency is confirmed. The systematic review of clinical guidelines emphasizes that supportive care is the cornerstone of management, and meticulous fluid management is fundamental to this supportive approach [1]. The case report on nursing care in the intensive care unit further reinforces that minimizing complications leading to sepsis, which is often precipitated by hemodynamic instability, is crucial to reducing mortality [3]. Therefore, maintaining strict fluid and electrolyte balance monitoring directly addresses the highest risk of acute decompensation and is the priority intervention.

Analysis of Correct Answer

Option 1: Maintain strict fluid and electrolyte balance monitoring.
This is the correct answer. In SJS, the loss of the epidermal barrier results in insensible fluid losses that are profound and continuous. Uncorrected, this leads to hypovolemia, prerenal azotemia, and electrolyte disturbances such as hypernatremia from free water loss or hyperkalemia from cellular breakdown and renal impairment. The management of SJS/TEN requires complex treatment and meticulous nursing care, with fluid resuscitation and ongoing monitoring being analogous to the protocols used for major burn patients [3]. Accurate intake and output records, daily weights, frequent vital sign assessment, and serial laboratory monitoring of serum electrolytes, blood urea nitrogen, and creatinine are non-negotiable nursing actions that directly prevent circulatory collapse and organ failure.

Analysis of Incorrect Options

Option 2: Apply topical antibiotics to all affected skin areas.
This is not the highest priority. While wound care is a critical component of SJS management to prevent secondary infection and sepsis, the indiscriminate application of topical antibiotics to all denuded areas is not a standard first-line intervention and can carry risks. Wound care protocols often prioritize non-adherent dressings, emollients, and specialized biological or biosynthetic coverings to protect the exposed dermis and promote re-epithelialization. Topical antimicrobials, particularly silver sulfadiazine, are generally avoided if a sulfonamide drug is the suspected trigger due to the risk of cross-reactivity and further immune activation. Even when indicated, wound care is a secondary priority to the immediate life-sustaining intervention of fluid resuscitation and hemodynamic stabilization [1].

Option 3: Encourage frequent oral hygiene with antiseptic mouthwash.
Oral mucosal involvement is a hallmark of SJS, causing severe pain, bleeding, and dysphagia, which impairs oral intake. Oral care is an essential comfort and infection-prevention measure. However, the use of antiseptic mouthwashes, particularly those containing alcohol or strong chemicals, can be excessively irritating to friable, denuded mucosa and may worsen pain. Gentle oral care with a soft sponge and non-irritating solutions is preferred. More importantly, while managing oral complications is a necessary nursing task, it does not supersede the critical need to monitor and manage life-threatening systemic fluid and electrolyte derangements [2].

Option 4: Position the patient in high Fowler's position continuously.
Continuous high Fowler's position is not a standard of care for SJS and could be detrimental. Patients with SJS are at high risk for skin breakdown and pressure injuries due to widespread epidermal loss. Immobility in a single position increases pressure on dependent areas, exacerbating tissue ischemia and the risk of new lesion formation. A pressure-relieving mattress and a meticulous, scheduled turning and repositioning regimen are essential to prevent pressure injuries and minimize pain. Positioning is a supportive intervention, but it is secondary to the immediate physiological priority of maintaining intravascular volume and electrolyte homeostasis [3].
