Intravenous (IV) therapy is a ubiquitous practice in healthcare settings, essential for administering fluids, medications, and nutrients. A fundamental concept within this therapy, particularly for determining baseline fluid needs, involves understanding what the 4 2 1 rule for IV fluids is.

Derived from the Holliday-Segar formula, the 4-2-1 rule is a rapid calculation method used by medical professionals to determine intravenous fluid maintenance rates. It simplifies complex medical needs, offering a quick answer to the question, 'What is the 4 2 1 rule for hydration?' for inpatients requiring intravenous fluid therapy.
