Final answer:
For post-cardiac arrest hypoperfusion, the PALS team would administer isotonic fluid boluses to restore intravascular volume and optimize preload, as they are safe and effective without causing destruction of red blood cells.
Step-by-step explanation:
In the context of Pediatric Advanced Life Support (PALS), when a child experiences post-cardiac arrest hypoperfusion after Return of Spontaneous Circulation (ROSC), it is crucial to restore intravascular volume and optimize preload to support cardiac output and improve perfusion. The appropriate type of fluid to administer to a child in this situation would be isotonic fluid boluses. These fluids, like normal saline or lactated Ringer's solution, have electrolyte compositions similar to that of blood, making them safe and effective for quickly expanding the intravascular volume without causing a shift in fluid between the intravascular and intracellular compartments.
An isotonic fluid bolus does not cause destruction of red blood cells; in contrast, if red blood cells are destroyed, as suggested in some scenarios, it could indicate that the fluid administered was not truly isotonic.
