When should empiric antibiotics be de-escalated in a septic ICU patient?
Answer: Once culture results identify the pathogen and sensitivities
De-escalation should occur once culture results identify the causative organism and its sensitivities, allowing narrow-spectrum therapy.
A burn patient in the ICU develops wound infection with pseudomonas. Which antibiotic class provides the most reliable anti-pseudomonal coverage?
Answer: Antipseudomonal beta-lactams (e.g., piperacillin-tazobactam)
Antipseudomonal beta-lactams such as piperacillin-tazobactam or cefepime are the cornerstone of Pseudomonas aeruginosa treatment.
Which intervention is most effective at preventing ventilator-associated events (VAE) in mechanically ventilated ICU patients?
Answer: Daily spontaneous awakening and breathing trials
Daily spontaneous awakening and breathing trials (SAT/SBT bundles) reduce ventilator days and are the most effective VAE prevention strategy.
A patient with severe sepsis has a central venous oxygen saturation (ScvO2) of 58%. What does this indicate?
Answer: Excessive oxygen consumption relative to delivery
ScvO2 below 70% indicates the tissues are extracting more oxygen than normal, reflecting inadequate oxygen delivery relative to demand.
Which patient population requires contact-plus (enhanced contact) precautions for MRSA in US hospitals?
Answer: Patients with known or suspected MRSA colonization or infection
Contact precautions are required specifically for patients with known or suspected MRSA to prevent nosocomial transmission.
What is the preferred method to confirm adequate source control in a septic patient with suspected intra-abdominal infection?
Answer: CT-guided drainage or surgical intervention to eliminate the infection source
Source control by CT-guided drainage or surgery to remove infected tissue or drain abscesses is essential and cannot be replaced by antibiotics alone.
