ACLS HEALTHCARE PROVIDER EXAMPREP
UPDATED COMPLETE QUESTIONS AND
VERIFIED SOLUTIONS
●● Taxonomy of Systems of Care:
Answer: SPSO: Structure, Process, System, Patient Outcome.
●● Post-Cardiac Arrest Syndrome:
Answer: Includes post-arrest brain injury, post-arrest myocardial
dysfunction, systemic ischemia or reperfusion response, and persistent
acute and chronic pathology that may have precipitated the cardiac
arrest.
●● Providers should titrate post-arrest phase inspired O2 to the lowest
possible level to achieve an arterial SPO2 of:
Answer: 94% or greater
●● Normocarbia
Answer: Partial pressure of end-tidal carbon dioxide [PETCO2] of 30-40
mmHg or PaCO2 of 35-45 mmHg) may be a reasonable goal unless
patient factors prompt more individualized treatment.
,●● Mild hypocapnia might be useful as a temporary measure when
treating:
Answer: cerebral edema
●● The optimal post-cardiac arrest blood pressure remains unknown;
however a mean arterial pressure of what is a reasonable goal?
Answer: 65 mmHg
●● Average survival rate of IHCA:
Answer: 24%
●● In a recent study, nearly 80% of hospitalized patients with
cardiorespiratory arrest had abnormal vital signs documented for up to
how many hours prior to the actual arrest?
Answer: 8 hours
●● More than half of IHCA are the result of:
Answer: respiratory failure or hypovolemic shock
●● The majority of IHCA are foreshadowed by changes in physiology,
such as:
Answer: tachypnea, tachycardia, and hypotension.
,●● Components of a rapid response system:
Answer: -Event detection and response triggering arm.
-A planned response arm, such as the RRT.
-Quality monitoring.
-Administrative support
●● Examples of physiologic criteria to determine when to call a RRT:
Answer: -Threatened airway
-Respiratory rate less than 6/min or more than 30/min
-Heart rate less than 40/min or greater than 140/min.
-Systolic BP < 90 mmHg
-Symptomatic hypertension
-Unexpected decrease in LOC
-Unexplained agitation
-Seizure
-Significant fall in urine output
-Subjective concern about the pt
●● Term to define team leaders who may become trapped in a specific
treatment or diagnostic approach-
Answer: Fixation error
, ●● In one human study, ROSC did not occur unless a CPP of what was
obtained during CPR?
Answer: 15 mmHg or greater
●● If hypoxia is presumed the cause of the cardiac arrest (such as in a
drowning patient):
Answer: 2 minutes of CPR prior to activating the emergency response
team should be delivered.
●● H's:
Answer: Hypovolemia, Hypoxia, Hydrogen Ion (acidosis), Hypo-
/hyperkalemia, Hypothermia
●● T's:
Answer: Tension pneumothorax, Tamponade (cardiac), Toxins,
Thrombosis (pulmonary), Thrombosis (coronary).
●● Common cause of PEA:
Answer: Hypovolemia
●● Hypovolemia, a common cause of PEA, produces classic physiologic
response of:
Answer: a rapid, narrow-complex tachycardia (sinus tachycardia), and
typically produces increased diastolic and decreased systolic pressures.
