What fluid would you use for the patient's fluid maintenance?

Rationale: A. Dextrose saline with potassium chloride (DSNS w/KCl) is not routinely used for maintenance; it is more specific for correcting electrolyte imbalances under close monitoring. B. Plasmalyte is an isotonic, balanced crystalloid solution that closely mimics plasma electrolyte composition and is appropriate for fluid maintenance. C. Lactated Ringer’s is mainly used for resuscitation (e.g., trauma, burns, surgery), not long-term maintenance. D. Normal saline (0.9% NaCl) is used for volume resuscitation or hyponatremia but can cause hyperchloremic metabolic acidosis if used for maintenance.
