A 45-year-old man with 30% total body surface area (TBSA) burns, including full-thickness wounds and suspected inhalation injury, is admitted to the ICU. His calculated Baux score is 75. On day 2, he develops hypotension (MAP 60 mmHg) despite fluid resuscitation and requires vasopressor support. Laboratory tests show creatinine rising from 0.9 to 2.1 mg/dL and lactate of 4.2 mmol/L, meeting Sepsis-3 criteria for septic shock. What is the most urgent management priority?

A 45-year-old male is admitted to the ICU after sustaining full-thickness burns covering 30% of his total body surface area (TBSA) in a house fire. His burn wounds exhibit significant eschar formation, placing him at high risk for invasive infection. Which of the following TOPICAL antimicrobial agents is most appropriate to prevent progression from colonization to invasive infection in this patient?

A 35-year-old male with 45% total body surface area (TBSA) full-thickness burns is admitted to the intensive care unit. On hospital day 3, he develops signs of sepsis but maintains preserved renal function. Considering the altered pharmacokinetics in severe burn patients—particularly increased volume of distribution from fluid shifts and augmented renal clearance—which initial vancomycin dosing strategy is most appropriate to achieve therapeutic plasma concentrations?

A 45-year-old man with 40% total body surface area burns is admitted to the ICU. Within hours, he develops fever, hypotension, and tachycardia consistent with sepsis. Blood cultures are pending. Given the high risk of multidrug-resistant organisms in burn patients and the need to balance immediate efficacy, antimicrobial stewardship, and pharmacoeconomic considerations, which empiric antimicrobial strategy is most appropriate?

A 35-year-old male with 40% total body surface area full-thickness burns is admitted to the burn ICU. He has been receiving vancomycin and piperacillin-tazobactam for 48 hours due to suspected wound infection. Despite therapy, new areas of sloughing tissue have developed on his burn wounds. Vital signs show a low-grade fever (38.0 °C) and mild tachycardia. Laboratory results reveal stable electrolytes, normal liver function tests, and creatinine at baseline. The critical care pharmacist is asked to recommend the most appropriate monitoring strategy to optimize antimicrobial therapy and assess efficacy. Which of the following should be prioritized for immediate review and potential adjustment?

A 35-year-old male (70 kg) with 40% total body surface area burns (day 3 post-injury) is admitted to the ICU. He develops acute kidney injury requiring continuous veno-venous hemodiafiltration (CVVHDF) at an effluent flow rate of 25 mL/kg/hr and is diagnosed with MRSA bacteremia. Given his severe burns, altered pharmacokinetics, and ongoing CRRT, what is the MOST appropriate vancomycin dosing strategy to achieve therapeutic targets while minimizing toxicity?

A 45-year-old man with 30% full-thickness burns is admitted to the ICU. On day 5, he develops fever of 39.2°C, tachycardia at 118 bpm, new-onset hypotension requiring norepinephrine support, and a rising white blood cell count from 8,500 to 18,200 /mm³. His burn wounds exhibit purulent exudate. The burn unit’s recent antibiogram reports methicillin-resistant Staphylococcus aureus (MRSA) in 35% of S. aureus isolates and multidrug-resistant Pseudomonas aeruginosa in 20% of Pseudomonas isolates. Considering his clinical deterioration and local resistance patterns, which empiric systemic antibiotic regimen is MOST appropriate to initiate at this time?

A 45-year-old man with 40% TBSA full-thickness burns (arms and torso) from a house fire was admitted to the ICU 48 hours ago. He now develops sepsis with temperature 39.0 °C, heart rate 120 bpm, blood pressure 85/50 mm Hg on low-dose norepinephrine, and lactate 4.5 mmol/L. His peripheral veins are largely unavailable due to burn wounds. He has a right subclavian central venous catheter placed on admission under full sterile precautions. The team plans aggressive fluid resuscitation and empiric broad-spectrum antibiotics. Considering infection prevention and optimal systemic delivery, which pharmacotherapy strategy should the critical care pharmacist prioritize?

A 45-year-old man with 40% TBSA full-thickness burns is admitted to the ICU. He is intubated, sedated, has a central venous catheter, and will undergo early excision and grafting within 48 hours. He is at high risk for venous thromboembolism (VTE), stress-related gastrointestinal bleeding, and central line–associated bloodstream infection (CLABSI). As the critical care pharmacist, which of the following comprehensive prevention strategies best addresses all three risks?

A 45-year-old patient with severe toxic epidermal necrolysis involving 60% of total body surface area is admitted to the ICU. The patient is currently receiving multiple invasive interventions, including vasopressor support and enteral nutrition. There is a high suspicion of sepsis, and broad-spectrum antibiotics are being considered. The patient’s family is visibly distressed and has expressed concerns about the prognosis and the extent of invasive treatments. As the critical care pharmacist, which action should you prioritize to best facilitate multidisciplinary goals of care and effective family communication?
