A primary health care provider orders a transdermal drug. When administering this drug, which action by the nurse would be most appropriate?
- A. Apply next dose to a new site.
- B. Check the infusion rate.
- C. Inject only the inner part of the forearm.
- D. Give small volumes of doses.
Correct Answer: A
Rationale: An important nursing intervention when administrating drugs through the transdermal route is to apply the next dose to a new site. It is important to check the infusion rate every 15 to 30 minutes in patients using infusion controllers or infusion pumps. When using the intradermal route, the inner part of the forearm should be used as the injection site and small volumes of doses should be administered.
