The client expresses worry about unintentionally giving an excessive amount of the painkiller and overdosing. The nurse should teach the client about PCA's dose and frequency restrictions.
Patient-controlled analgesia (PCA), a technique for treating pain, allows you to decide when to take a dose of pain medicine. In some cases, PCA might be a better way to manage pain than asking someone to give you painkillers, which is frequently done by a nurse. When you have PCA, there is no need to wait for a nurse. PCA is used when oral analgesia or intermittent IV morphine boluses would not be sufficient to manage moderate to severe pain.
Thus, it follows that the client should be taught by the nurse about the dose and frequency restrictions built into the PCA.
