Final answer:
An infusion pump tubing with an infusion pump is the best option for maintaining strict control over the volume of medication delivered to a patient.
Step-by-step explanation:
The infusion set that should be used to maintain strict control over the volume of fluid or medication delivered is an infusion pump tubing with an infusion pump (Option C). While a Buretrol® provides control over volume, and a microdrip can deliver small volumes, neither offer the precise control for rate and volume as an infusion pump does. An infusion pump ensures accurate and continuous administration of fluids, medications, or nutrients at specific flow rates and can hold various types of infusion sets to match the therapy needed for the patient.
