Question 1

Dobutamine is preferred over norepinephrine in which hemodynamic state?

Accepted Answer

Cardiogenic shock with low cardiac output and adequate blood pressure

Answer

Dobutamine's positive inotropic effect makes it the agent of choice when pump failure (low CO) is the primary problem with a relatively preserved MAP.

Question 2

Beck's triad (hypotension, JVD, muffled heart sounds) is classic for which emergency?

Accepted Answer

Cardiac tamponade

Answer

Beck's triad — hypotension, jugular venous distension, and muffled heart sounds — is the clinical hallmark of cardiac tamponade.

Question 3

What ECG finding is pathognomonic for ST-elevation myocardial infarction (STEMI)?

Accepted Answer

ST elevation ≥ 1mm in ≥ 2 contiguous leads

Answer

STEMI is diagnosed by ST elevation ≥ 1 mm in at least two contiguous leads representing the same coronary territory.

Question 4

Which medication should be avoided in right ventricular infarction with hypotension?

Accepted Answer

Nitroglycerin (preload reducers)

Answer

RV infarction depends on adequate preload; nitroglycerin reduces venous return, worsening hypotension in this setting.

Question 5

What is the recommended CPR compression-to-ventilation ratio for adults with an advanced airway in place?

Accepted Answer

Continuous compressions at 100–120/min with 1 breath every 6 seconds

Answer

Once an advanced airway is secured, continuous chest compressions at 100–120/min are given while ventilations are delivered asynchronously at 1 breath every 6 seconds.
