Question

Quizplus · Accepted Answer

The nurse should select the largest bore cannula possible. An 18-gauge cannula is the largest size available. A 24-gauge cannula would be the smallest. IV access is initiated for hydration prior to epidural placement and for use in an emergency. Both require the rapid administration of fluid, which is most easily accomplished with a large bore cannula.
