What is a sign that indicates a potential problem in a post-operative client using a PCA pump?

Increased sedation can indicate a potential problem in a post-operative client using a PCA (patient-controlled analgesia) pump. This condition may signify that the patient is receiving too much opioid medication, which could lead to respiratory depression, impaired cognitive function, and decreased response to stimuli. For patients on PCA pumps, the goal is to manage pain effectively while minimizing side effects. Increased sedation is a critical side effect that requires prompt assessment and intervention, as it can lead to serious complications if not addressed.

Severe pain over the operated site could be expected after surgery, especially if the anesthesia wears off, requiring potential adjustments in pain management but is not, in itself, an immediate sign of an issue with the PCA pump. Decreased urine output may indicate fluid balance issues or need for further evaluation, but it is not directly related to opioid over-sedation. Frequent nausea can occur with opioid use but is not as critical as sedation levels, which can have more immediate consequences.
