A post-operative patient is oliguric with urine Na of 8 mEq/L and FENa <1%. What is the MOST likely cause?
Answer: Pre-renal azotemia
FENa <1% with low urine sodium indicates avid tubular sodium reabsorption, consistent with pre-renal azotemia from decreased effective circulating volume.
Which finding is MOST consistent with ARDS on a chest X-ray?
Answer: Bilateral fluffy infiltrates in a non-cardiogenic pattern
ARDS produces bilateral, diffuse alveolar infiltrates without cardiomegaly or vascular redistribution, reflecting non-cardiogenic pulmonary edema.
What is the purpose of the CAM-ICU tool in the acute care setting?
Answer: Screen for delirium in ICU patients
The Confusion Assessment Method for the ICU (CAM-ICU) is a validated tool for detecting delirium in mechanically ventilated and non-verbal ICU patients.
A patient in cardiogenic shock has a cardiac index of 1.8 L/min/m² and PCWP of 24 mmHg. Which hemodynamic profile does this represent?
Answer: Cold and wet cardiogenic shock
Low cardiac index (18) indicates cold and wet cardiogenic shock — poor forward flow with volume overload.
Which electrolyte abnormality is a common COMPLICATION of massive blood transfusion?
Answer: Hyperkalemia from stored RBCs combined with metabolic alkalosis from citrate
Massive transfusion causes hypocalcemia (citrate chelates calcium) and initially hyperkalemia from stored RBCs, though citrate metabolism later produces alkalosis.
A patient with status epilepticus fails lorazepam and fosphenytoin. What is the NEXT step in management?
Answer: Initiate propofol or midazolam infusion for refractory status
Refractory status epilepticus (failing two adequate medications) requires continuous IV anesthetic infusion (propofol, midazolam, or pentobarbital) with EEG monitoring.
Which acid-base disorder is MOST commonly associated with prolonged nasogastric suctioning?
Answer: Metabolic alkalosis
Nasogastric suctioning removes hydrochloric acid (H+ and Cl-), leading to metabolic alkalosis and hypochloremia.
