ACLS Principles Flashcard 8

B. Rationale: Chest compressions should not be interrupted for > 10 seconds for rhythm checks, pulse checks, using an AED, switching compressors, or any other reason.

D. Rationale: A post-resuscitation debriefing should be conducted following any resuscitation effort. This debriefing should include lay rescuers, EMS personnel, and any other indiviuals involved in the resuscitation effort.

A. RATIONALE: The loading dose of magnesium sulfate is 1–2 g IV/IO diluted in 10 mL D5W or NS and given as a bolus, typically over 5 to 20 minutes.

C. Rationale: For cardiac arrest in a pregnant patient, the resuscitation team should include neonatal teams to care for the newborn if delivered.

B. Rationale: PEA is organized electrical activity without a pulse, whereas asystole exhibits no electrical activity on the monitor—it appears as a flatline rhythm.

D. Rationale: PEA used to be known as electromechanical dissociation and is similar to asystole in treatment. It is not a shockable rhythm.

A. Rationale: Sequential defibrillation is not recommended for individuals in cardiac arrest. There is no evidence to support the use of nearly simultaneous shocks for an individual in a shockable cardiac arrest rhythm.

D. Rationale: Some studies have shown that survival rates are lower if a resuscitation is performed at nighttime and over the weekends compared to weekdays. It is inferred that healthcare institutions are understaffed on the weekends and at nighttime.

A. Rationale: Some studies have shown that survival rates are lower when resuscitations are performed at nighttime and over the weekends compared to weekdays. It is inferred that healthcare institutions are understaffed on the weekends and at nighttime.

A. Rationale: Studies have shown that there is an increase in ROSC incidence, survival to hospital discharge, and improved neurologic outcomes if epinephrine was given between 1 and 3 minutes after the onset of cardiac arrest compared to its administration at a later time.
