Question 1

A patient presents with aortic dissection type A. What is the most critical immediate management step?

Accepted Answer

Emergency surgical repair

Answer

Type A aortic dissection involving the ascending aorta carries 1-2% mortality per hour without surgery and requires immediate operative intervention.

Question 2

Which finding on arterial blood gas analysis is most consistent with acute cyanide poisoning?

Accepted Answer

Metabolic acidosis with high venous oxygen saturation

Answer

Cyanide inhibits cytochrome c oxidase, blocking cellular oxygen utilization, causing lactic acidosis with paradoxically high venous PO2 as cells cannot extract oxygen.

Question 3

In a patient with acute coronary syndrome, which antiplatelet agent is preferred alongside aspirin for PCI?

Accepted Answer

Ticagrelor 180mg loading dose

Answer

Ticagrelor with a 180mg loading dose is preferred over clopidogrel in ACS because it provides faster, more consistent, and greater platelet inhibition.

Question 4

What is the correct management for a child with epiglottitis presenting with stridor and drooling?

Accepted Answer

Calm environment, avoid agitation, secure airway in OR

Answer

Children with epiglottitis should be kept calm to avoid complete airway obstruction; intubation should be performed in a controlled OR setting with ENT available.

Question 5

A patient is brought in with organophosphate poisoning. Which combination of antidotes is required?

Accepted Answer

Atropine and pralidoxime (2-PAM)

Answer

Atropine blocks muscarinic effects of acetylcholine excess while pralidoxime reactivates acetylcholinesterase if given before aging of the enzyme-inhibitor complex.
