Monitoring protocols for a patient receiving treatment for hypernatraemia include:

Measure plasma electrolyte concentrations every 4 to 6 hours during the first 24 hours of treatment, then adjust the frequency of monitoring based on the patient's response to treatment.
Ensure that the rate of fall of plasma sodium does not exceed 12 mmol/l in a 24-hour period to avoid complications.
Regularly assess fluid status and adjust intravenous fluid prescriptions accordingly, including consideration of changing to hypotonic fluids if hypernatraemia worsens or remains unchanged after initial treatment.
Monitor clinical response closely, including signs of dehydration or fluid overload, and reassess fluid management plans if the patient is transferred to a different care setting.

These steps help safely correct hypernatraemia while minimizing risks associated with rapid sodium changes and fluid mismanagement.
