Bolus

Definition

A single, large dose of medication given all at once, typically intravenously. The medical equivalent of ripping off a band-aid instead of peeling it slowly.

Example Usage

The nurse administered a bolus of saline to bring up the patient's blood pressure, delivering a liter faster than a college student chugs beer.

Origin

From Greek 'bolos,' meaning 'lump' or 'clod'

Fun Fact

The term also applies to the chewed lump of food you swallow, making it simultaneously relevant in both the IV room and at the dinner table.
