BLS Post-Resuscitation Care 4

Question 1

Which temperature range defines fever that should be actively prevented in comatose post-arrest patients?

Accepted Answer

Above 37.5°C

Answer

Fever is defined as ≥37.5°C in post-arrest guidelines, and active prevention is recommended to protect neurological outcomes.

Question 2

Which finding on EEG is associated with poor neurological prognosis after cardiac arrest?

Accepted Answer

Burst suppression with identical bursts

Answer

Burst suppression with identical (stereotyped) bursts is a malignant EEG pattern predictive of poor neurological outcome.

Question 3

A post-arrest patient's CT scan of the head shows loss of gray-white matter differentiation. What does this indicate?

Accepted Answer

Diffuse anoxic brain injury

Answer

Loss of gray-white matter differentiation on CT indicates diffuse cerebral edema from anoxic brain injury, a poor prognostic sign.

Question 4

What is the primary goal of targeted temperature management (TTM) when implemented after cardiac arrest?

Accepted Answer

Provide neuroprotection by reducing cerebral metabolic demand

Answer

TTM reduces cerebral oxygen demand and inflammatory injury, providing neuroprotection during the vulnerable post-arrest period.

Question 5

Why is hyperoxia harmful in the post-resuscitation period?

Accepted Answer

It worsens reperfusion injury through free radical production

Answer

Excess oxygen after ROSC generates reactive oxygen species that exacerbate reperfusion injury in ischemic tissues, particularly the brain.
