Final answer:
The child needs immediate IV/IO access and administration of fluids for the treatment of shock.
Step-by-step explanation:
In this case, the child is presenting with symptoms of shock, including lethargy, tachycardia, hypotension, and delayed capillary refill time. Immediate intravenous (IV) or intraosseous (IO) access is required for the administration of fluids and medications.
The type of fluid administered will depend on the cause of shock. In the case of hemorrhagic shock, blood products may be administered. In other cases, crystalloids like normal saline or balanced electrolyte solutions may be given to restore fluid volume.
It is important for the healthcare professional to assess the underlying cause of the shock and treat accordingly. This may involve additional interventions, such as treating infection or addressing other contributing factors.
