Describe the primary pathophysiologic mechanism in sepsis-related acute respiratory distress
syndrome (ARDS).
Increased capillary permeability leading to alveolar flooding and impaired gas exchange.
What is the most common electrolyte disturbance in critically ill patients receiving diuretics?
Hypokalemia.
Explain the role of norepinephrine in the management of septic shock.
It increases vascular tone by acting on alpha-adrenergic receptors to counteract vasodilation
and restore blood pressure.
What is the main complication of prolonged mechanical ventilation in critically ill patients?
Ventilator-associated pneumonia (VAP).
What is the most common cause of acute liver failure in the ICU?
Acetaminophen overdose.
In a patient with traumatic brain injury (TBI), why is hyperventilation used to control intracranial
pressure (ICP)?

, What is the first-line treatment for cardiogenic shock in the ICU?
Inotropic support, typically with dobutamine.
How does continuous renal replacement therapy (CRRT) differ from intermittent hemodialysis in
critically ill patients?
CRRT is slower, allowing for more gentle fluid and electrolyte removal, reducing the risk of
hemodynamic instability.
What is the purpose of permissive hypercapnia in ARDS management?
To prevent lung injury from high tidal volumes while accepting higher carbon dioxide levels
to maintain adequate oxygenation.
In a patient with acute pancreatitis, what is the most important initial step in management?
Aggressive fluid resuscitation.
What is the primary clinical sign of tension pneumothorax in a critically ill patient?
Tracheal deviation to the opposite side.
Why is lactate used as a marker in sepsis?
Elevated lactate indicates tissue hypoperfusion and anaerobic metabolism.
What is the most common cause of death in patients with severe burns in the ICU?
