What term describes rapid administration of pressor medications?

• A. Bolus infusion
• B. Push-dose pressor
• C. IV drip
• D. Continuous infusion

Answer: (B)

Push-dose pressor is the approach used when you need a quick, controllable lift in blood pressure. It involves giving small, rapid IV pushes of a vasopressor to produce an immediate rise in mean arterial pressure, with the doses and timing easily adjusted based on the patient’s response. This lets you achieve rapid hemodynamic improvement while you set up a longer-term plan or transition to a continuous infusion.

Drips or continuous infusions aim for a steady, maintained effect rather than quick, on-the-spot titration, so they’re slower to produce abrupt changes. A bolus infusion can refer to a rapid single dose, but it isn’t the standardized method for ongoing, adjustable pressor support. The term that best describes rapid administration of pressors is push-dose pressor because it specifically denotes these rapid, titratable boluses.
