A 32-year-old male is admitted to the ICU following a high-speed motor vehicle collision. He is hypotensive (BP 85/50 mmHg), tachycardic (120 bpm), and has a Glasgow Coma Scale score of 14. Initial labs reveal a hemoglobin of 9 g/dL and lactate of 4 mmol/L, consistent with hemorrhagic shock. While awaiting availability of blood products, which initial fluid resuscitation strategy aligns best with current evidence-based trauma guidelines?

An 82-year-old man is admitted to the ICU after surgical evacuation of a right subdural hematoma following a fall. He remains intubated and mechanically ventilated. On arrival, his mean arterial pressure (MAP) is 65 mmHg, intracranial pressure (ICP) is 18 mmHg, and central venous pressure (CVP) is 6 mmHg. There is no ongoing hemorrhage, but imaging shows early cerebral edema. Given his advanced age and severe TBI, which of the following initial fluid resuscitation strategies best optimizes cerebral perfusion pressure while minimizing the risk of fluid overload and worsening edema?

A 45-year-old male (weight 70 kg) is admitted to the ICU after severe blunt abdominal trauma. He is mechanically ventilated, receiving norepinephrine at 7 mcg/min via a central line, and has already received 4 L of normal saline during initial resuscitation. On ICU arrival, he remains hypotensive with a mean arterial pressure of 58 mmHg despite vasopressor support. Laboratory results show hemoglobin 7.2 g/dL, lactate 6.2 mmol/L, and base deficit −8 mEq/L. Physical exam reveals abdominal distension, bilateral leg edema, and urine output <0.5 mL/kg/h. Considering his ongoing hemorrhage, impaired oxygen-carrying capacity, and the known harms of excessive crystalloids, which fluid management strategy should the critical care pharmacist prioritize?

A 35-year-old male with multiple long-bone fractures and a pelvic hematoma from a motor vehicle collision is admitted to the trauma ICU. He is receiving a massive transfusion protocol of packed red blood cells and plasma at a 1:1 ratio. His vital signs are: HR 120 bpm, BP 90/60 mm Hg (MAP 70 mm Hg), RR 24 breaths/min, SpO₂ 98% on 2 L NC. Central venous lactate is 4.0 mmol/L, base deficit is –6 mEq/L, INR 1.4, platelets 100×10⁹/L. He has received 3 L of IV fluids (2 L normal saline, 1 L lactated Ringer’s) and 4 units of blood products. Which of the following fluids is MOST appropriate to continue resuscitation?

A 45-year-old male involved in a high-speed motor vehicle collision has received 4 liters of lactated Ringer’s solution in the emergency department. Despite this aggressive fluid resuscitation, he remains hypotensive (80/45 mmHg), tachycardic (130 bpm), and has produced only 15 mL of urine in the past hour. He is intubated on assist-control mechanical ventilation. Laboratory studies reveal metabolic acidosis consistent with ongoing shock. Considering his persistent hypovolemic shock despite adequate volume resuscitation, what is the MOST appropriate immediate pharmacologic and supportive management?

A 35-year-old male with multiple long-bone fractures and a pelvic hematoma from a motor vehicle collision is admitted to the trauma ICU. He is sedated, mechanically ventilated, and immobilized in the ICU. Neurosurgery confirms secured hemostasis with no ongoing bleeding. To provide venous thromboembolism (VTE) prophylaxis in this high-risk patient, which pharmacologic intervention is most appropriate?

A 65-year-old, 80 kg male with a history of type 2 diabetes mellitus and hypertension is day 3 of hospitalization in the ICU for community-acquired pneumonia and sepsis. He remains mechanically ventilated with stable hemodynamics (BP 120/75 mm Hg, HR 88 bpm), normal lactate (1.2 mmol/L), creatinine 1.0 mg/dL, and albumin 2.5 g/dL. A 10-French nasogastric feeding tube was placed 24 hours ago. The patient is tolerating 1.5 kcal/mL polymeric enteral formula at 60 mL/hour, with gastric residual volumes consistently <150 mL. The critical care pharmacist is transitioning his medications from IV to enteral administration via the nasogastric tube. Which of the following actions should the pharmacist prioritize to minimize complications such as tube occlusion and ensure therapeutic efficacy?

A 45-year-old male trauma patient (weight 70 kg) is in the ICU following initial resuscitation for multiple injuries. He is hemodynamically stable with blood pressure 120/75 mmHg, heart rate 85 bpm, and respiratory rate 16 breaths/min. Urine output has been steady at 0.8 mL/kg/hr over the past 6 hours, and serum lactate has decreased to <2 mmol/L, indicating adequate tissue perfusion. He has been receiving lactated Ringer’s solution at 2.1 mL/kg/hr (≈147 mL/hr) since admission. Physical exam shows no signs of compartment syndrome or pulmonary edema. Given his stable status and the goal of safely de-escalating fluid therapy, what is the MOST appropriate next step in his fluid management?

A 45-year-old male trauma patient with multiple fractures and a traumatic brain injury is admitted to the ICU. He requires prolonged mechanical ventilation and sedation. The critical care team is concerned about his high risk for Post–Intensive Care Syndrome (PICS), which includes long-term cognitive and physical impairments. As the critical care pharmacist, which intervention should you prioritize to effectively mitigate this patient’s risk of PICS?

A 45-year-old, 70 kg male with no significant past medical history sustained 35% TBSA partial- and full-thickness burns 10 hours ago in a house fire. He was intubated for airway protection and resuscitated with the Parkland formula (4 mL/kg/%TBSA) during the first 24 hours. His baseline creatinine is 0.9 mg/dL, and his current urine output is 0.5–1 mL/kg/hr. He remains on low-dose norepinephrine (0.05 mcg/kg/min) with stable hemodynamics. As the critical care pharmacist preparing a handoff to a specialized burn center, which element should you prioritize MOST in the transfer documentation to ensure continuity of care?
