BLS Post-Resuscitation Care 3

Question 1

A post-arrest patient develops a mean arterial pressure (MAP) of 55 mmHg. What is the recommended MAP target?

Accepted Answer

Above 65 mmHg

Answer

A MAP ≥65 mmHg is the minimum recommended target to ensure adequate organ perfusion after cardiac arrest.

Question 2

When is neuroprognostication typically considered reliable after cardiac arrest?

Accepted Answer

At least 72 hours after ROSC (or after rewarming)

Answer

Neuroprognostication should not occur before 72 hours post-ROSC (or after rewarming) because sedatives and hypothermia can confound findings.

Question 3

Which of the following is a POOR prognostic indicator for neurological recovery post-cardiac arrest?

Accepted Answer

Bilaterally absent N20 SSEP waves

Answer

Bilaterally absent N20 somatosensory evoked potential waves at ≥72 hours strongly predict poor neurological outcome.

Question 4

Post-cardiac arrest syndrome (PCAS) includes which combination of conditions?

Accepted Answer

Brain injury, myocardial dysfunction, systemic ischemia/reperfusion response, and persistent precipitating pathology

Answer

PCAS encompasses brain injury, myocardial dysfunction, systemic ischemia/reperfusion response, and the underlying cause of arrest.

Question 5

Which vasopressor is most commonly used to treat post-resuscitation hypotension?

Accepted Answer

Norepinephrine

Answer

Norepinephrine is the preferred vasopressor for maintaining MAP ≥65 mmHg in post-cardiac arrest shock.
