An RN is teaching a student nurse about tissue plasminogen activator (tPA) administration in a patient with ischemic stroke. Which statement made by the student nurse indicates a need for further teaching?
"tPA should be administered within 12 hrs of the onset of a stroke."
"tPA is administered by intraarterial infusion."
"tPA is administered IV."
"PA requires BP monitoring during and 24 hrs after the treatment."
The Correct Answer is A
A. tPA (tissue plasminogen activator) should be administered within 3 to 4.5 hours of the onset of ischemic stroke symptoms, not 12 hours. Administering it after this window increases the risk of complications such as bleeding.
B. tPA is administered by intraarterial infusion is true, but it refers to a specific technique for certain stroke types.
C. tPA is administered IV is correct for intravenous administration in many cases of ischemic stroke.
D. tPA requires BP monitoring during and 24 hrs after the treatment is accurate as blood pressure control is critical when administering tPA.
