    any other route
     GI absorption impaired
  • Administer medications

Q

what are the risks of IV therapy?

A
  • phlebitis, ecchymosis, extravascular fluid infiltration, infection,
    thrombosis, and venous spasm.

Q

what are the benefits of IV therapy?

A

Giving drugs IV is rapid and effective
Drugs can also be delivered long term by continuous infusion, or
over short period, directly as single dose.
