Commonly used fluids: (RL, NS, Dextrose, Half Normal Saline)

Electrolytes become imbalanced when body loss the fluid for any reason, body systems are stressed, and cognitive function in the brain is impaired. As a result, urine output is decreased. When blood is “thicker,” the heart has to work harder, causing the pulse to increase in order to maintain blood pressure. Replacement of fluids intravenously resolves the imbalance and restores normal body functions.
