A client presents with a partial-thickness burn covering 20% of their total body surface area (TBSA) after an industrial accident. What is the most appropriate initial action by the nurse to manage fluid resuscitation for this client?

Start administering 1000 mg of Vancomycin IV immediately to prevent infection.

Administer 4 mL of lactated Ringer's solution IV per kg of body weight per TBSA.

Provide oral fluids until the client is stable.

Wait for 24 hours before starting any fluid resuscitation.
