Question 1

In managing a patient with acute ischemic stroke, what is the maximum time window for IV alteplase from symptom onset?

Accepted Answer

4.5 hours

Answer

IV alteplase can be administered within 4.5 hours of symptom onset in eligible patients with acute ischemic stroke per current guidelines.

Question 2

A patient in the ICU develops acute respiratory distress syndrome (ARDS). What tidal volume is recommended for lung-protective ventilation?

Accepted Answer

6 mL/kg predicted body weight

Answer

The ARDSNet trial established that 6 mL/kg predicted body weight reduces mortality compared to conventional 12 mL/kg ventilation in ARDS.

Question 3

Which antidote is used for acetaminophen (paracetamol) overdose?

Accepted Answer

N-acetylcysteine

Answer

N-acetylcysteine replenishes glutathione stores and is the antidote for acetaminophen toxicity, most effective within 8-10 hours of ingestion.

Question 4

In a patient with diabetic ketoacidosis, when should insulin infusion be started?

Accepted Answer

After potassium > 3.5 mEq/L is confirmed

Answer

Insulin should not be started until serum potassium is ≥3.5 mEq/L because insulin drives potassium intracellularly and can precipitate life-threatening hypokalemia.

Question 5

A trauma patient with a Glasgow Coma Scale (GCS) of 8 requires airway management. What is the most appropriate approach?

Accepted Answer

Rapid sequence intubation (RSI)

Answer

GCS ≤8 indicates inability to protect the airway and mandates definitive airway management via rapid sequence intubation in trauma patients.
