When a client’s husband questions how a patient-controlled analgesia (PCA) pump works, the nurse explains that the client:

1. Has control over the frequency of the intravenous (IV) analgesia
2. Can choose the dosage of the drug received
3. May request the type of medication received
4. Controls the route for administering the medication

With a PCA system the client controls medication delivery. The PCA system is designed to de-liver no more than a specified number of doses. The client does not choose the dosage. The health care provider prescribes the type of medication to be used. The advantage for the client is that he or she may self-administer opioids with minimal risk for overdose. The client does not control the route for administration. Systemic PCA typically involves IV drug administration but can also be given subcutaneously.
