How is an IV bolus administered?
Bolus doses of medication may be injected directly through an existing venous access device or through an implanted port. The medication administered by these methods usually takes effect rapidly, so the patient must be monitored for an adverse reaction, such as cardiac arrhythmia and anaphylaxis. IV bolus injections are contraindicated when rapid drug administration could cause life-threatening complications. The safe rate of injection is specified by the drug’s manufacturer.
