Final answer:
The recommended initial intervention for managing hypotension after ROSC is c) administering intravenous fluids.
Step-by-step explanation:
The recommended initial intervention for managing hypotension in the immediate period after return of spontaneous circulation (ROSC) is option c) administer intravenous fluids.
Hypotension after ROSC may occur due to inadequate circulating volume, so administering intravenous fluids helps to increase the blood volume and restore blood pressure. This intervention is crucial for ensuring adequate perfusion to the organs and improving the chances of a favorable outcome.
