Question 1

Which hemodynamic pattern is classic for cardiogenic shock?

Accepted Answer

Low CO, high SVR, high PCWP

Answer

Cardiogenic shock is characterized by low cardiac output, compensatory high systemic vascular resistance, and elevated pulmonary capillary wedge pressure reflecting fluid backup.

Question 2

The first-line vasopressor for septic shock per Surviving Sepsis Guidelines is:

Accepted Answer

Norepinephrine

Answer

Norepinephrine is recommended as the first-choice vasopressor for septic shock due to its superior vasoconstrictive effect and favorable safety profile.

Question 3

What is the classic ECG finding in hyperkalemia that precedes ventricular fibrillation?

Accepted Answer

Peaked T waves progressing to wide QRS

Answer

Hyperkalemia produces progressive ECG changes from peaked T waves to widened QRS complex, which can degenerate into ventricular fibrillation if untreated.

Question 4

In a patient with pulseless electrical activity (PEA), which of the following is a reversible cause?

Accepted Answer

Tension pneumothorax

Answer

Tension pneumothorax is one of the 5 H's and 5 T's reversible causes of PEA arrest and requires immediate needle decompression.

Question 5

What is the appropriate initial energy for defibrillation of ventricular fibrillation with a biphasic defibrillator?

Accepted Answer

120–200 J

Answer

Biphasic defibrillators typically use 120–200 J for the initial shock in ventricular fibrillation, following manufacturer recommendations.
