The nurse assesses a client receiving dialysis who is hypotensive with a blood pressure of 88/42 and complaining of dizziness and nausea. Which action should the nurse prioritize?

Rationale: A. Notifying the healthcare provider is important but not the immediate priority. Hypotension during dialysis can lead to rapid organ hypoperfusion; immediate interventions to stabilize the client take precedence over notification. B. Decreasing the volume of blood being removed (ultrafiltration rate) is appropriate in the longer-term management of dialysis hypotension, but it may not provide immediate relief for an acutely hypotensive client experiencing symptoms like dizziness and nausea. C. Bolusing the client with 300 mL of 0.9% saline solution is the priority action. Hypotension during dialysis is often caused by rapid fluid removal, leading to intravascular volume depletion. Administering isotonic saline immediately restores intravascular volume, improves blood pressure, relieves symptoms, and prevents complications such as syncope or organ hypoperfusion. D. Placing the client in the reverse Trendelenburg position (head up, feet down) would worsen hypotension because it reduces venous return to the heart. The proper positioning for hypotension is usually Trendelenburg (head down, feet elevated) to improve perfusion.
