Complication

On the exam, complication items hand you a post-op or post-procedure client and ask “which finding should the nurse report first?” — the tell is a subtle change in trend, not an obvious crisis. The answer almost always hinges on the earliest sign of deterioration, so a rising respiratory rate (the most sensitive early vital sign), restlessness, or new confusion outranks a stable “abnormal but expected” value, because early subtle changes beat dramatic late ones in priority. Watch the post-op timeline trap: pneumonia and DVT emerge over days, while hemorrhage threatens within hours.

Don’t confuse the concept with its tools. Monitoring is the ongoing surveillance that catches a complication; telemetry is one narrow window (primarily cardiac rhythm); hemorrhage is one specific complication. Students wrongly treat “watch closely” or “recheck in an hour” as a complete answer — but anticipating and preventing the complication outranks merely observing it. Memory hook: prevent, then detect, then escalate.
