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

Infection prevention is the highest priority in SJS due to compromised skin barrier and high mortality from sepsis. Strict aseptic technique and monitoring for signs of infection are critical, while other interventions are supportive but secondary.

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing intervention for a patient with Stevens-Johnson syndrome (SJS). SJS is a severe, life-threatening mucocutaneous reaction, often drug-induced, characterized by extensive epidermal detachment and necrosis. The pathophysiology involves massive apoptosis of keratinocytes, leading to widespread blistering, sloughing of skin and mucous membranes, and a profound loss of the body's primary barrier against infection. The most common and lethal complication is Key Point! sepsis, which is the leading cause of death in SJS/TEN (Toxic Epidermal Necrolysis). Therefore, nursing care is centered on preventing and detecting infection.

Answer Rationale: Option ④ is correct because it directly addresses the primary threat to the patient's life. The extensive loss of skin and mucosal barriers creates a situation analogous to a massive burn wound, making the patient exquisitely vulnerable to pathogens. Key Point! Monitoring for signs of infection (e.g., fever, increased WBC, changes in wound exudate, tachycardia, hypotension) and maintaining strict aseptic technique during all wound care and procedures are fundamental, life-preserving actions. This aligns with the nursing process principle of prioritizing problems based on Maslow's Hierarchy of Needs, where physiological safety (preventing life-threatening sepsis) takes precedence.

Distractor Analysis:
Watch out for confusion! Option ①, "Apply topical antibiotics to all affected skin areas," is incorrect and potentially harmful. Topical antibiotics are not routinely applied to all denuded areas in SJS/TEN. Their use is selective and based on culture results, as indiscriminate use can promote resistance and some topical agents (e.g., silver sulfadiazine) are contraindicated due to sulfa components, which are a common trigger. The priority is aseptic technique and protective dressings, not medication application.
Option ②, "Administer oral corticosteroids as prescribed," is a secondary intervention. The use of systemic corticosteroids in SJS is highly controversial and not a standard of care. Some protocols may use IV immunoglobulins (IVIG) or other immunosuppressants. Even if prescribed, administering medication is important but does not supersede the constant, vigilant monitoring and technique required to prevent the main complication.
Option ③, "Provide emotional support and counseling," is a crucial aspect of holistic care but is a lower priority. While the psychological impact of this disfiguring and painful condition is immense, addressing the imminent physiological threat of infection must come first according to the ABCs (Airway, Breathing, Circulation) and survival needs.

Related Concepts: SJS is on a spectrum with Toxic Epidermal Necrolysis (TEN), differentiated by the extent of body surface area (BSA) involvement. Common triggers include medications (sulfonamides, anticonvulsants, NSAIDs, allopurinol). Nursing management also prioritizes fluid and electrolyte balance (due to massive fluid loss), pain management, and ocular and mucosal care to prevent long-term sequelae like blindness and strictures.

Nursing Clinical Practice Guide Clinical Scenario: You are assigned to a 28-year-old patient admitted with a diagnosis of SJS, suspected to be triggered by a new antibiotic. The patient has painful bullae and erosions covering approximately 20% of their BSA, including the oral mucosa, lips, and conjunctivae. They are febrile (38.5°C/101.3°F) and tachycardic.

Nursing Intervention Strategy: 1. Assessment: Perform a thorough head-to-toe assessment every 4 hours or more frequently. Use a Braden Scale for pressure ulcer risk (score will be very low). Monitor vital signs meticulously for signs of sepsis (fever, tachycardia, tachypnea, hypotension). Assess wounds for signs of infection: purulent drainage, increased erythema, foul odor, and worsening pain. 2. Infection Control: Adhere to strict contact precautions. Use a private room. Don gown and gloves for all patient contact. Perform meticulous hand hygiene before and after. Handle the patient's skin with extreme gentleness; do not forcibly remove adhered clothing or dressings. 3. Wound Care: Collaborate with the wound care team. Typically, denuded areas are covered with non-adherent, protective dressings (e.g., petrolatum-impregnated gauze, silicone mesh). Key Point! Maintain aseptic technique during all dressing changes. Debride necrotic tissue only as per protocol. Document wound appearance and extent daily. 4. Mucosal Care: Provide frequent oral care with saline or prescribed solutions. Apply prescribed ocular lubricants frequently to prevent corneal abrasions and synechiae. Monitor for dysphagia and provide nutritional support (often via NG tube or TPN). 5. Pain Management: Administer IV analgesics (often opioids) on a scheduled basis, as pain is severe and constant. Assess pain using a validated scale.

Patient Safety and Precautions: - Medication Alert: Immediately discontinue the suspected causative drug. Verify all new medications with the pharmacist to avoid cross-reactivity. - Fluid Management: Closely monitor intake and output. Weigh the patient daily. Large volumes of IV fluids may be required to replace insensible losses, similar to burn management. - Environmental Safety: Use a pressure-relieving mattress. Keep the room warm to minimize heat loss through denuded skin.
Nursing Procedure & Medication Flow Wound Dressing Change Procedure (Aseptic Technique): 1. Gather supplies in a clean area: sterile gloves, non-adherent dressing, sterile saline, sterile basin, tape, biohazard bag. 2. Perform hand hygiene and don a clean gown and gloves. 3. Gently remove old dressing. If it adheres, moisten with sterile saline. 4. Discard old dressing immediately into biohazard bag. 5. Remove soiled gloves, perform hand hygiene, and don sterile gloves. 6. Cleanse the wound gently with sterile saline using a single, one-way stroke for each gauze piece. 7. Apply the new non-adherent dressing. 8. Secure dressing. Dispose of all waste. Perform hand hygiene.
Medication Caution: Be vigilant about Watch out for confusion! administering any drug from the common "high-risk" categories for SJS (sulfa drugs, certain anticonvulsants, allopurinol, NSAIDs). Always double-check the patient's allergy profile.

A Word from Your Senior Nurse "SJS is one of the most visually distressing and medically urgent conditions you'll encounter. Your role is to be a vigilant guardian at the bedside. That constant monitoring for a subtle fever spike or a change in the wound's character isn't just a task—it's a lifesaving intervention. In the exam and in practice, when you see 'compromised skin barrier,' think 'SEPSIS RISK' first. Mastering the priority of infection control here will help you answer not just SJS questions, but any question involving major breaks in skin integrity, from burns to severe wounds."
