A nurse is caring for a client with toxic epidermal necrolysis (TEN). Which nursing intervention should be the highest priority?

Airway monitoring is the highest priority in SJS due to mucosal involvement that can lead to respiratory failure. Infection prevention is important but secondary to airway management.

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for a patient with Toxic Epidermal Necrolysis (TEN), a severe, life-threatening skin reaction often triggered by medications. The core pathophysiology involves widespread keratinocyte apoptosis (cell death), leading to full-thickness epidermal detachment, similar to a severe burn. This results in massive fluid and electrolyte loss, a high risk of sepsis, and potential mucous membrane involvement (eyes, mouth, respiratory tract, genitals).

Answer Rationale: The correct answer is ② Encourage oral fluid intake to maintain hydration. Key Point! In TEN, the loss of the skin barrier function causes profound insensible fluid loss, leading to hypovolemia, electrolyte imbalances (especially hyponatremia and hypokalemia), and potential renal failure. Maintaining hydration and hemodynamic stability is the absolute Key Point! foundation upon which all other care depends. While oral intake may be limited by painful oral mucosal involvement, aggressive IV fluid resuscitation is the standard of care, and the nursing priority is to support this goal, which includes encouraging oral fluids if tolerated.

Distractor Analysis:
• Watch out for confusion! Option ①, "Apply topical antibiotics to all affected skin areas," is incorrect. While infection prevention is critical, TEN skin is managed with sterile, non-adherent dressings and topical antiseptics (e.g., silver sulfadiazine), not routine topical antibiotics. Applying antibiotics to all areas is not standard and does not address the immediate life-threatening issue of fluid loss.
• Option ③, "Administer prescribed corticosteroids immediately," is a common misconception. The use of systemic corticosteroids in TEN is controversial and often contraindicated due to increased risk of sepsis, poor wound healing, and gastrointestinal bleeding. First-line treatment often involves IV immunoglobulin (IVIG) or immunosuppressants like cyclosporine, not corticosteroids.
• Option ④, "Monitor for signs of respiratory distress and airway compromise," is a very high priority but is not the highest priority in the initial management sequence. Watch out for confusion! While mucosal sloughing can lead to airway obstruction (a true emergency), the foundational ABC (Airway, Breathing, Circulation) approach must be followed. Circulation (fluid resuscitation) supports perfusion and prevents shock, which is the most immediate and pervasive threat. Airway monitoring is essential and often the second priority, but without adequate circulation, airway management efforts will fail.

Related Concepts: TEN is the most severe form of a spectrum that includes Stevens-Johnson Syndrome (SJS). Management principles are similar to burn care. The SCORTEN score is used to predict mortality. Nursing care focuses on wound care, infection control, pain management, nutritional support, and psychosocial care.

Concept Summary • Patho: Drug-induced keratinocyte apoptosis → epidermal detachment → massive fluid/protein loss.
• Priority #1: Fluid & Electrolyte Resuscitation (like a major burn).
• Priority #2: Airway protection & monitoring for mucosal involvement.
• Priority #3: Aseptic wound care & infection prevention.
• Treatment: Stop offending drug, supportive care, IVIG/immunosuppressants.
• Key Complication: Sepsis, ARDS (Acute Respiratory Distress Syndrome), renal failure.

Side-by-Side Comparison!

Feature	Stevens-Johnson Syndrome (SJS)	Toxic Epidermal Necrolysis (TEN)
Skin Detachment	<10% of body surface area (BSA)	>30% of BSA
Mortality	~5%	25-40%+
Primary Nursing Focus	Airway, mucous membrane care, pain	Fluid resuscitation, then airway, then wound/sepsis
Common Triggers	Anticonvulsants, antibiotics, allopurinol, NSAIDs	Same as SJS (often same drugs)

Anatomy, Physiology & Pharmacology Points • Skin Physiology: The epidermis is a vital barrier preventing fluid loss and infection. Its destruction leads to hypovolemic shock and hypermetabolic state.
• Drug Mechanism: Offending drugs (e.g., sulfonamides, lamotrigine) are thought to trigger a cytotoxic T-cell mediated immune response against keratinocytes.
• IV Fluids: Resuscitation often uses formulas like the Parkland formula (4 mL x kg x %TBSA burned) as a guide, with lactated Ringer's solution.

Memory Tips • Think "BURN": TEN management parallels major Burn care: Breathing/Airway, Urinary output (for fluid assessment), Resuscitation (Fluids!), Nutrition & wound care.
• Priority Order: "First Fill the Tank, Then Protect the Pipe." The "tank" is circulatory volume (fluids), the "pipe" is the airway.

High-Frequency NCLEX Topics NCLEX loves testing priority-setting in life-threatening conditions. For any condition causing massive fluid loss (burns, TEN, cholera), fluid resuscitation is almost always the first priority after ensuring a patent airway. Be ready to distinguish between urgent (airway) and immediately life-threatening (circulatory collapse) needs.

Watch Out for Question Variations! • Variation 1: "Which assessment finding requires immediate intervention?" → Answer: Decreased urine output (<30 mL/hr) or hypotension, indicating hypovolemia.
• Variation 2: "The nurse should prepare for which procedure first?" → Answer: Insertion of a large-bore IV catheter for fluid administration.
• Variation 3: Shift to SJS: "A client with SJS has painful oral ulcers. Which intervention is priority?" → Answer: Providing frequent oral care and ensuring airway patency might take precedence over fluids if oral involvement is severe and threatening the airway.

Nursing Clinical Practice Guide Clinical Scenario: You are assigned to Mr. Johnson, 68, admitted to the Burn/ICU unit with a diagnosis of TEN (60% BSA involvement) 48 hours after starting a new antibiotic for a UTI (Urinary Tract Infection). He is lethargic, tachycardic (HR 122), hypotensive (BP 88/50), and has decreased skin turgor. His oral mucosa is erythematous with blistering.

Nursing Intervention Strategy:
1. Assessment: Immediate VS (Vital Signs), strict I&O (Intake and Output), daily weights, assess extent of skin detachment (Rule of Nines), monitor for signs of sepsis (fever, confusion, worsening WBC), and frequent respiratory assessment for stridor or increased work of breathing.
2. Nursing Diagnosis: Deficient Fluid Volume related to massive insensible losses; Risk for Infection; Impaired Skin Integrity; Acute Pain.
3. Planning & Implementation:
• Fluid Resuscitation: Collaborate with the team to administer prescribed IV fluids (often Lactated Ringer's) via large-bore IVs. Goal: Maintain urine output at 0.5-1 mL/kg/hr.
• Wound Care: Perform sterile wound care with non-adherent dressings (e.g., petrolatum gauze, silicone mesh). Use aseptic technique. Never debride intact blisters.
• Airway Management: Provide humidified oxygen. Collaborate with respiratory therapy. Prepare for possible intubation if respiratory distress develops.
• Pain & Comfort: Administer IV opioids via PCA (Patient-Controlled Analgesia) pump as ordered. Position carefully on pressure-relieving surfaces.
4. Evaluation: Is urine output adequate? Are VS stabilizing? Is there no sign of active respiratory distress? Are wounds clean without purulent drainage?

Patient Safety and Precautions:
• Infection Control: Strict contact isolation (gown, gloves). Reverse isolation/protective environment may be used.
• Medication: Immediately discontinue the suspected causative drug. Verify all future medication allergies.
• Skin: Handle patient with extreme care; use lift sheets. Avoid adhesive tapes.

Nursing Procedure & Medication Flow • IV Fluid Administration: Calculate drip rates carefully. For example, if ordered 1000 mL over 8 hrs with a 20 gtt/mL set: (1000 mL x 20 gtt/mL) / (8 hrs x 60 min) = ~42 gtt/min. Use an IV pump for precision.
• Medication: IV Immunoglobulin (IVIG): Administer slowly as per protocol (often over several hours) to prevent fluid overload and adverse reactions (headache, chills, anaphylaxis). Pre-medicate with acetaminophen and diphenhydramine as ordered.

A Word from Your Senior Nurse "TEN patients are some of the most critically ill and vulnerable people you will care for. They are in immense pain and are literally losing their protective shell. Your vigilance in monitoring their fluid status—every drop of urine output, every subtle change in blood pressure—is what keeps them alive. Remember the basics: airway, breathing, circulation. In TEN, the 'circulation' part is a massive, ongoing battle. Don't just follow orders; understand the 'why' behind the aggressive fluids. You are their first line of defense against shock and sepsis. This kind of critical thinking is exactly what the NCLEX tests and what makes an exceptional nurse."
