What is the immediate management plan for a patient presenting with vomiting and dehydration?

The immediate management plan for a patient presenting with vomiting and dehydration involves addressing the loss of fluids and electrolytes. Administering an intravenous bolus of normal saline is essential in this scenario because it provides a rapid rehydration option, particularly in cases where oral rehydration is not feasible due to the severity of vomiting or the inability to keep fluids down. Normal saline is isotonic and helps to quickly restore intravascular volume, improving circulation and preventing shock.

Other interventions like administering dextrose could be beneficial later in the management plan, particularly if there’s concern over hypoglycemia, but it does not address the immediate fluid deficit. Providing an oral rehydration solution can be effective in cases of mild dehydration but is generally not appropriate for patients who are actively vomiting or unable to maintain hydration orally. Pain management, while important in a comprehensive care approach, does not address the critical need for fluid resuscitation in this acute situation. Thus, the use of normal saline as an immediate intervention is the correct and necessary course of action.
