A 28-year-old female with Type 1 diabetes presents with severe hyperglycemia, metabolic acidosis, and ketonuria. Her blood pressure is 90/60 mmHg, and she appears dehydrated. What is the most appropriate initial intravenous fluid for resuscitation?

✓ Correct Answer: Option D

Initial fluid resuscitation in DKA, especially in hypotensive or severely dehydrated patients, should begin with 0.9% normal saline (isotonic) to restore intravascular volume before switching to hypotonic solutions or adding dextrose.
