A 68-year-old man is admitted to the ICU with severe agitation and visual hallucinations consistent with delirium, confirmed by a positive CAM-ICU assessment and a Richmond Agitation-Sedation Scale (RASS) score of +4. His history includes coronary artery disease and hypertension. Current medications are metoprolol and aspirin. An ECG shows a borderline prolonged QTc interval of 460 ms. Rapid control of his agitation is necessary to prevent harm to himself and staff. Considering his clinical presentation, medications, and cardiac history, which of the following pharmacologic interventions is the MOST appropriate initial step in managing his severe agitation and delirium?

A 65-year-old male in the ICU with acute kidney injury (AKI) requiring continuous renal replacement therapy (CRRT) is exhibiting severe agitation (RASS +4). He weighs 70 kg, has stable hemodynamics (BP 115/70 mmHg, HR 88 bpm), and normal liver function tests. Which sedative regimen is MOST appropriate to minimize drug accumulation and adverse effects while effectively controlling agitation?

A 56-year-old man with severe sepsis is admitted to the ICU. He has developed significant capillary leak syndrome with third spacing and hypoalbuminemia (albumin 2.0 g/dL). He requires antibiotic therapy with a hydrophilic drug that is highly protein-bound. Considering these pharmacokinetic changes, which of the following is the most appropriate adjustment to his drug therapy?

A 68-year-old man with septic shock is receiving mechanical ventilation in the ICU. He is on low-dose norepinephrine (0.05 µg/kg/min) and has a baseline QTc of 450 ms. On ICU day 3, he becomes agitated, pulling at his endotracheal tube and impeding ventilator synchrony despite nonpharmacologic measures. Vital signs are: BP 120/65 mm Hg, HR 85 bpm, RR 20 (ventilator), SpO₂ 96% on FiO₂ 40%. Labs are unremarkable. Considering both pharmacoeconomic factors (drug acquisition cost and monitoring burden) and safety (respiratory depression, QTc prolongation), which agent is the MOST favorable for initial management of his agitated delirium?

A 68-year-old, 80 kg male with a history of coronary artery disease (post–myocardial infarction 5 years ago) and hypertension is admitted to the ICU for community-acquired pneumonia complicated by hyperactive delirium. He has been receiving intravenous haloperidol 5 mg every 6 hours for 24 hours (last dose 2 hours ago). His baseline ECG shows a QTc of 460 ms. Vital signs: HR 92 bpm, BP 135/75 mm Hg, RR 20 breaths/min, T 37 °C. Daily labs: K⁺ 4.2 mEq/L, Mg²⁺ 1.9 mg/dL. Current monitoring includes CAM-ICU and RASS assessments every 8 hours and daily electrolytes. As the ICU pharmacist, which of the following additions to his monitoring plan is most critical for safety?

A 68-year-old male patient in the ICU is critically ill, intubated, and receiving vasopressors. He is transitioning to comfort measures only due to a poor prognosis. The patient is unable to take oral medications because of intubation and decreased consciousness. He is exhibiting signs of delirium and agitation requiring pharmacologic management for symptom control. Considering his clinical status and goals of care, which of the following is the MOST appropriate initial pharmacotherapy plan for managing his delirium and agitation?

A 65-year-old male patient has been mechanically ventilated in the ICU for 5 days following severe pneumonia complicated by septic shock. He is receiving a propofol infusion at 5 mcg/kg/min, targeting a RASS of –1 to 0, but is currently at RASS +1 to +2 with persistent restlessness and attempts to self-extubate, delaying planned ventilator weaning. His vital signs are HR 110 bpm, BP 105/60 mm Hg on norepinephrine 0.05 mcg/kg/min, SpO₂ 95% on FiO₂ 40%. Laboratory tests show creatinine 1.2 mg/dL and AST/ALT <2× ULN; he has no severe hepatic failure. According to the 2018 PADIS guidelines for ICU sedation and delirium, which of the following pharmacologic interventions is most appropriate to add to his current sedation regimen to manage his agitated delirium and facilitate extubation?

A 65-year-old ICU patient on haloperidol for delirium develops sudden fever, muscle rigidity, altered mental status, and rising creatine kinase levels. Which of the following is the most appropriate initial management?

Mr. Thomas is a 78-year-old man admitted to the ICU with septic shock secondary to pneumonia. He has advanced dementia, end-stage renal disease on dialysis, and chronic heart failure. Despite treatment with haloperidol and supportive care, he remains delirious and agitated. The ICU team is considering highly invasive interventions, including tracheostomy and PEG tube placement, to prolong life. Given his persistent delirium and multiple comorbidities, what should the critical care pharmacist prioritize as the most crucial next step in his care plan?

A 68-year-old man with severe sepsis is intubated and mechanically ventilated for 3 days in the ICU and requires norepinephrine for septic shock. His laboratory studies show a platelet count of 98,000/µL and an INR of 1.6. Which of the following interventions should be prioritized to prevent stress-related mucosal bleeding in this patient?
