What is typically the maximum volume of a bolus given in mL?

In intravenous therapy, the term "bolus" refers to the administration of a concentrated dose of medication or fluid over a short period, usually to achieve a rapid therapeutic effect. The maximum volume of a bolus that is generally accepted for safe administration in adults is typically considered to be less than 60 mL. This threshold is established to minimize the risk of complications such as fluid overload, adverse reactions, or damage to the venous system.

Administering a bolus greater than this volume can increase the risk of side effects or complications, especially in patients who may have underlying health conditions, such as heart or kidney issues, that require careful monitoring of fluid intake. Therefore, the choice of less than 60 mL reflects a standard practice that balances effective treatment with patient safety, making this answer the most fitting in the context of pharmacology in radiology.
