Place the nursing actions in order when a client's condition worsens and the initial provider response does not resolve the safety concern.

Correct sequence
Protect and reassess → communicate urgency and recommendation → read back and name the unresolved risk → escalate through rapid response or chain of command → document the timeline.

Why this is correct
Chain of command is a patient-safety mechanism, not a courtesy ladder. The RN does not abandon immediate care while seeking an order and does not keep repeating the same ineffective contact when the client is deteriorating.

NCLEX decision rule
When delay creates harm, act within scope, mobilize resources, and escalate until responsibility and an adequate plan are clear.
