An infant with diarrhea is dehydrated. IV fluids have been ordered to restore fluid balance. The most effective device used to prevent fluid overload is:
a. A precision-controlled syringe pump
b. A piggyback setup
c. A tunneled IV catheter
d. A 15-drop infusion set
A
A syringe or other in-line volume-control device is often used because they hold a limited amount of fluid. Only that fluid can be administered at one time. A piggyback setup would be used to infuse a dose of medication, not a continuous infusion. Neither a tunneled catheter nor a 15-drop infusion set would protect the child from fluid overload.
