Question 1

Which ventilator strategy is recommended for patients with Acute Respiratory Distress Syndrome (ARDS) to minimize ventilator-induced lung injury?

Accepted Answer

Low tidal volume (6 mL/kg ideal body weight) with high PEEP

Answer

Lung-protective ventilation using low tidal volumes of 6 mL/kg ideal body weight and appropriate PEEP reduces barotrauma and improves outcomes in ARDS.

Question 2

A patient arrives in the emergency department with suspected opioid overdose. Which medication should be administered immediately?

Accepted Answer

Naloxone 0.4–2 mg IV/IM/IN

Answer

Naloxone is a competitive opioid antagonist that rapidly reverses opioid-induced respiratory depression and altered consciousness.

Question 3

In the trauma primary survey, what does the 'C' in the modified <C>ABCDE approach stand for?

Accepted Answer

Catastrophic hemorrhage control

Answer

In the modified <C>ABCDE approach, 'C' stands for Catastrophic hemorrhage control, which takes priority even before airway management in major trauma.

Question 4

Which of the following is a contraindication to thrombolytic therapy in ischemic stroke?

Accepted Answer

Recent intracranial surgery within 3 months

Answer

Recent intracranial surgery, severe head trauma, or prior stroke within 3 months are absolute contraindications to thrombolytic therapy due to the risk of hemorrhagic transformation.

Question 5

What is the initial energy dose recommended for defibrillation of ventricular fibrillation using a biphasic defibrillator?

Accepted Answer

150–200 joules

Answer

Biphasic defibrillators are typically used at 150–200 joules for the initial shock in ventricular fibrillation, which is effective and reduces myocardial damage compared to monophasic devices.
