Feedback:
The most common and potentially dangerous adverse effect related to an osmotic diuretic is the sudden drop in fluid levels. Mannitol peaks 1 hour after administration, therefore, it would be most important to monitor blood pressure. Weight is the best indicator over time but would not be as effective in indicating a dangerous fluid drop as the blood pressure. Respiratory and pulse rates would also not be as effective as blood pressure in evaluating dangerous fluid drops.
