When administering mannitol, which factor should be closely monitored to avoid complications?

When administering mannitol, it is crucial to closely monitor serum electrolytes due to the osmotic effects of this medication. Mannitol is a hyperosmotic diuretic that draws water out of cells and into the bloodstream, leading to an increased urine output. This process can cause significant changes in electrolyte balance, particularly resulting in potential shifts in sodium and potassium levels.

Monitoring serum electrolytes is essential to prevent complications such as hypernatremia or hyponatremia, which can lead to serious neurological effects or cardiac issues. Additionally, mannitol can cause renal complications, and changes in serum electrolyte levels can be indicative of renal function status. It is important to ensure that electrolyte levels remain within the normal range to maintain homeostasis and prevent adverse reactions associated with imbalances.

The other areas, like bowel health, skin integrity, or temperature, do not directly correlate with the administration of mannitol and its primary effects on fluid and electrolyte balance. Although they are all important aspects of patient care, they are not the key focus when managing a patient on mannitol therapy.
