There was an order for a male patient in his 60s of mannitol 50 ml every 4 hours. The first 2 doses were given correctly, but in the third dose, unfortunately there was an over infusion, 175 ml was given instead of 50 ml only. Patient's blood pressure was 120/80 for 3 hours monitoring after the overdose. What are the precautionary measures for untoward events that may happen?
