Case Study

A 45-year-old client in the emergency department is being evaluated for nursing care related to osmosis and tonicity. Assessment data include vital signs change from earlier: blood pressure 94/60 mm Hg and heart rate 112/min. Which nursing action is the priority to keep the client safe?

Question

D. Administer the next scheduled intervention before reassessing the client.

Rationale

Correct answer: B. Stay with the client, remove immediate hazards, reassess, and escalate per facility safety protocol.
