A nurse is teaching an alert client how to use a PCA system in the home. How will she explain to the client what he must do to self-manage pain?
A) "You don't have to do anything. The machine does it all."
B) "I will teach your family what they need to do."
C) "When you push the button, you will get the medicine."
D) "The medicine is going into your body all the time."
Ans: C
When the sensation of pain occurs, the client pushes a button that activates the PCA device to deliver a small preset bolus dose of the analgesic. A lockout interval (usually 5 to 10 minutes) prevents reactivation of the pump and administration of another dose during that period of time. Other safeguards also limit the possibility of overmedication.
