Final answer:
A clinician bolus in PCA delivery includes an additional dose of medication given by a healthcare provider when standard PCA dosing is inadequate for pain management.
Step-by-step explanation:
The term clinician bolus in the context of Patient-Controlled Analgesia (PCA) delivery refers to an additional dose of medication that is administered by a healthcare provider to supplement the pain management regimen. This is generally done in situations where the patient's pain is not adequately controlled by the standard PCA dosing. The clinician bolus can be a crucial component of PCA delivery, as it allows for the healthcare team to respond to a patient’s varying and sometimes immediate need for additional pain relief without waiting for the next scheduled dose or exceeding the safety limits of the PCA device.
