Question 72

IV infusion is a route of administration where a dose is given gradually over a period of time.

IV infusion delivers medication continuously or in controlled doses over an extended duration, allowing for precise management of drug levels in the bloodstream.

A) IV admixture

IV admixture refers to the preparation of a medication by combining it with another solution or drug, typically before administration. While it is part of the preparation process, it does not specifically denote a method of gradual dosing over time.

B) IV bolus (IVB)

An IV bolus involves administering a large volume of medication quickly, usually over a few minutes. This method contrasts with gradual administration, as it delivers the entire dose at once rather than over a prolonged period.

C) IV infusion

IV infusion is characterized by the gradual delivery of medication over a set time frame, making it the correct answer. This method allows for steady medication levels and is often used for treatments requiring continuous drug administration.

D) IV piggyback (IVPB)

IV piggyback is a method of administering a secondary medication through an existing IV line, typically using a small volume of fluid. While it can involve gradual administration, it does not define a standalone method of administration over an extended period like an IV infusion does.

Conclusion

IV infusion is the definitive answer as it clearly describes the gradual administration of medication over time, which is essential for maintaining therapeutic drug levels. In contrast, the other options either pertain to different methods of administration or do not focus on the gradual delivery of a dose.
