A nurse is a member of a quality-improvement committee seeking to reduce the risk of adverse events in a health care facility. When reviewing recently submitted incident reports, which of the following incidents should the nurse identify as a sentinel event?

The correct answer is B: Paralysis of a client's lower extremities occurred following epidural anesthesia. This incident should be identified as a sentinel event because it resulted in a serious harm or death to the patient. Sentinel events are defined as unexpected occurrences involving death or serious physical or psychological injury. In this case, the paralysis of the client's lower extremities following epidural anesthesia qualifies as a serious physical injury. The other choices do not meet the criteria for a sentinel event: A did not result in harm, C did not result in client injury, and D involves a complaint of cultural insensitivity which, while important, does not meet the criteria of a sentinel event.
