BLS Post-Resuscitation Care 5

Question 1

Which of the following BEST describes the multimodal approach to neuroprognostication?

Accepted Answer

Combining clinical exam, EEG, SSEP, biomarkers, and neuroimaging

Answer

No single test is sufficiently reliable; combining clinical findings, electrophysiology, biomarkers, and imaging improves prognostic accuracy.

Question 2

What is 'post-cardiac arrest shock' primarily characterized by?

Accepted Answer

Hypotension with low cardiac output due to myocardial dysfunction

Answer

Post-arrest shock involves global myocardial stunning causing low cardiac output and hypotension requiring vasopressor or inotropic support.

Question 3

A post-arrest patient on mechanical ventilation has a PaO2 of 350 mmHg on 100% FiO2. What action should be taken?

Accepted Answer

Wean FiO2 down to achieve SpO2 of 92–98%

Answer

Hyperoxia (PaO2 >300 mmHg) is harmful; FiO2 should be weaned to maintain SpO2 92–98%, avoiding excessive oxygen exposure.

Question 4

Which patient population is MOST likely to benefit from emergent PCI after resuscitation from out-of-hospital cardiac arrest?

Accepted Answer

Patients with STEMI or high suspicion of acute coronary occlusion on ECG

Answer

Emergent PCI is most beneficial when STEMI or signs of acute coronary occlusion are present on post-ROSC ECG.

Question 5

What complication does aggressive hyperventilation cause in post-arrest patients?

Accepted Answer

Cerebral vasoconstriction reducing cerebral blood flow

Answer

Hyperventilation lowers PaCO2, causing cerebral vasoconstriction and reduced cerebral blood flow, worsening ischemic brain injury.
