A client's serum sodium is 118 mEq/L and the client is confused. Which precaution should the nurse put in place?

Study tip
  • Study emergencies as a sequence: what you see, what it means, what you do first (DKA, sepsis, stroke, PE, anaphylaxis, tension pneumothorax).
  • Review fluid and electrolyte imbalances by their ECG and neuromuscular signs (peaked T waves, Chvostek and Trousseau signs).
