Question 72

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

IV infusion allows for the continuous delivery of medications or fluids into a patient's bloodstream over an extended period, ensuring steady drug levels and improved therapeutic effects.

A) IV admixture

IV admixture refers to the process of mixing a medication with an intravenous solution before administration. While it involves preparing a medication for infusion, it does not itself describe a method of gradual administration over time.

B) IV bolus (IVB)

An IV bolus involves delivering a single, concentrated dose of medication rapidly into the bloodstream. This method does not provide gradual administration; rather, it is an immediate introduction of the drug, making it the opposite of what the question specifies.

C) IV infusion

IV infusion is the correct choice as it involves the gradual administration of medication or fluids over a set duration. This method ensures that the patient receives a consistent and controlled dosage, which is crucial for maintaining therapeutic levels.

D) IV piggyback (IVPB)

IV piggyback refers to the method of administering a secondary IV solution alongside a primary infusion. While it can involve gradual delivery, it is not explicitly defined as a standalone route of administration that focuses on the gradual dosing of a single medication over time.

Conclusion

IV infusion is clearly the correct answer, as it specifically describes a method of gradual medication delivery over time, unlike IV admixture, IV bolus, and IV piggyback, which do not meet the criteria set by the question. Understanding these distinctions is vital in clinical practice for effective medication administration.
