NEVER ADD KCl TO A HANGING IV BAG| Best app for NEET PG Preparation |Dopamine|

Never add Potassium Chloride (KCl) to an IV bag that is already hanging and running into a patient, as the potassium may not mix evenly and could create a dangerously concentrated dose that reaches the patient first; always take the bag down, add KCl carefully, mix thoroughly, verify the order, then restart the infusion.
