What is iv fluid made up of?

IV (intravenous) fluid is typically composed of a sterile solution of water and electrolytes, such as sodium, potassium, calcium, and chloride, along with glucose or other nutrients, depending on the specific formulation. Common types of IV fluids include isotonic solutions like normal saline (0.9% sodium chloride) and lactated Ringer's solution, as well as hypotonic and hypertonic solutions for specific medical needs. These fluids are used to maintain hydration, restore electrolyte balance, and deliver medications.
