ACLS Review Questions: Post Cardiac Arrest Care

01. The answer is: c. 32 – 36.  Unconscious adult patients with spontaneous circulation after out-of-hospital cardiac arrest should be cooled to 32°C to 34°C for 12 to 24 hours when the initial rhythm was ventricular fibrillation (VF).  It should be maintained for at least 24 hours after reaching target temperature.
02. The answer is: a. Septal wall infarction
03. The incorrect answer is: c. Prophylactic administration of an antiarrhythmic medication should be initiated to suppress further dysrhythmias.
04. The answer is: c. 72 hours.  The earliest time for prognostication using clinical examination in patients treated with TTM, where sedation or paralysis could be a confounder, may be 72 hours after return to normothermia. This approach minimizes the possibility of obtaining false-positive results (ie, inaccurately suggesting a poor outcome) because of drug-induced depression of neurologic function
05. The answers are: a. Hypotension, b. Distended neck veins, c. Muffled heart tones, and d. Pulsus paradoxus.  Collectively, hypotension, distended neck veins, and muffled heart tones are called Beck’s triad.
