How much isotonic IV fluid is generally administered per hour?

When it comes to the administration of isotonic IV fluids, the recommended hourly rate often falls within the range of 75-100 cc/hr in many clinical settings, particularly for general hydration and maintenance of fluid balance in stable patients. This range allows for sufficient fluid replacement for daily needs without overwhelming the patient's cardiovascular system.

This rate is typically based on considerations such as the size and weight of the patient, as well as their specific medical conditions and needs. It ensures that patients receive adequate hydration while minimizing the risk of fluid overload, which can lead to complications like pulmonary edema or electrolyte imbalances.

In contrast, the other options present higher or lower rates that, while they might be suitable in certain contexts (such as bolus administration in emergent situations), are generally not the standard for routine isotonic fluid maintenance. The selected range strikes a balance that is commonly accepted in practice, making it the most appropriate choice for general scenarios.
